Don't Ignore These On Dash Warning Lights?

DASH WARNING LIGHTS ON CAR, TRUCK, VAN AND JEEP


The basic warning lights which is noticed on dashboard should not be ignored.Get the exact cause for why these warning light occurred.
If you just ignore these warning lights,you never know when these warning lights will get converted into major car problems.

The warning lights just comes up on dash,that you look into the problem.

Its not always necessary that problem will be major,sometimes its very minor issue like loose wiring or dirty wiring and cleaning the wiring helps to clear the warning light.

MOST COMMON WARNING LIGHTS NOTICED ON MOSTLY ALL TYPES OF VEHICLES


  • OIL PRESSURE WARNING LIGHT
  • TEMPERATURE WARNING LIGHT
  • CHARGING SYSTEM WARNING LIGHT
  • BRAKE WARNING LIGHT
  • LOW TIRE WARNING LIGHT
There are many other different types of warning lights,but these are most common and noticed on mostly all types of vehicles.
Some new model vehicles will have some extra additional warning lights indication to alert the driver.
The  warning light details and indications are provided in cars owners manual.

But these details are basic.To get Complete details i suggest you to,
Go through the details and important aspects which tells you what does these warning lights mean and what are the possible cause for the particular warning light to appear on your cars dash board and what basic troubleshooting step you can take to get rid of this warning light indicator.

Please Note on some cases the basic troubleshooting does not help and onsite inspection is required by professional car mechanic or Auto repair shops technician.

OIL PRESSURE WARNING LIGHT ON DASH:

The dash indicator will show these Icon on the dash board panel.
dash warning light

When you see these warning light on dash board.Please don't ignore it.Just get the oil level checked.Either oil level is got low or oil is leaking.The engine needs particular oil pressure to function.When the oil pressure gets less then its required engine operation.The oil pressure warning light will illuminate.

Possible causes for Oil pressure light:--
  • These light comes up if oil level is low or oil is leaking.
  • The oil just now filled is wrong or very thin oil filled.
  • Oil pressure sending unit is weak or INOP.
  • Oil Pump is got very old and not holding pressure.
  • Or its due to excessive Engine bearing clearance.
Common problems noticed:---

When engine oil gets low and you still drive then ticking,clicking types of noise from engine.Even if you continue driving with these noise then further you will notice major engine damage.The repair cost may be high.On some cases engine rebuilt or replacement is required.

WHAT SHOULD BE DONE WHEN OIL PRESSURE WARNING LIGHT IS SHOWN

When oil pressure warning light is ON. Stop driving the vehicle.Check the oil level.There is a dipstick on most of vehicle models to check the oil level.If the oil level is shown less on dipstick mark.Then fill the exact correct oil to its required level.Then turn the car off,then ON.These will reset the system and Warning light should go out.

But in some cases the driver ignores these oil warning light and keep driving and due to these engine parts starts getting damaged.You notice problem like rapping,tapping,knocking types of sound when the engine starts.But these is start of problem.Just get the vehicle tune up done to engine mechanical working parts and oil level corrected.

On some cases its seen that oil is filled/changed but again in few week or days the low oil level or oil pressure light comes up.This indicates that either your engine is burning the oil or there is a oil leakage.
There are pressure tool available at local auto parts store.These tool an test if pressure is accurate or low.If pressure is not holding at one position,that means there is a leak.If there a leak,it can be repaired.At local car garage the leaking seal and gasket will be easily identified and replaced.
Also on some cases its seen that oil filter gets worn out or not properly replaced can cause oil leak.So without forget inspect the condition as well as position of oil filter.

But if you notice that no oil is getting leaked and its pressure shows perfect then its confirmed that the oil is burning.The function of the oil is to run through the engine mechanical parts to keep the moving parts, bearing,gears etc lubricated.But if oil is burning then mostly the repair is major.The valve guides,cylinders,engine bearings getting worn out.

On some of the old model vehicles there is a sensor fitted in the oil pan.This sensor detects the level of oil in the pan.Some these sensor itself gets worn out or its connections gets loose.So these sensor will not detect the oil level and due to that low oil level light will come up on dash.If your vehicle has oil level sensor,then without forget get the sensor checked.

Another reason for low oil pressure can be worn out oil pump.Basically these pumps and hoses are made up of rubber or important high resistant plastic type materials.When these parts gets old by age and worn out.You will notice that oil pressure is perfect when engine is cold but oil issues get noticed after driving for some miles.This happens because when engine gets warm,its components gets bit expanded,when engine is cold,the components are intact.And when oil pump or hoses or seals or gaskets gets bit expanded the pressure gets released.So in that case it can be faulty oil pump.Or its issue with oil filter or problem with oil pick up screen in engine crank case.


TEMPERATURE WARNING LIGHT ON DASH:

The dash indicator will show this Icon on dash board panel.
Temp Warning
On some vehicles the dash board Just Shown TEMP on Display.

Temperature warning light of dash is indication of engine overheating.There are many possibilities,for why the engine is overheating.But its advisable to stop driving and confirm the cause of problem.Once the problem is corrected you are safe to drive.But if vehicle is over heating and you still drive,then engine will definitely get damaged.

Possible causes for engine overheating:

Getting temp warning light and engine overheating noticed.
  • It can be due to low coolant level or coolant leaking.
  • The problem with radiator and heater hoses.
  • Head gasket leaking.
  • Cracked cylinder head.
  • Serpentine belt loose or broken.
  • Bad water pump.
  • Thermostat is stuck up.
  • Radiator engine cooling fan/s not working or faulty.
  • Dirty,clogged or faulty radiator itself.
  • Exhaust restriction.
  • Catalytic converter issue( Plugged CATS).

WHAT SHOULD BE DONE WHEN TEMP WARNING LIGHT IS SHOWN

The temperature warning light comes up when engine is overheating.First of get the coolant level checked.If its low,fill up the coolant to required level.If the cooling system is the cause of problem,then filling the coolant reservoir to its required level will correct the issue.Turn the car off for a minute then ON.These will reset the system after coolant is filled.

Other possibilities that can cause vehicle to over heat are driving in hot condition or towing trailer of high capacity then suggested,driving condition,driving habits,stop and go driving in traffic.
When the engine gets hot,the cooling system functions to control the heat.But when vehicle gets overloaded the cooling systems capacity gets out of reach to cool the engine and vehicle starts getting overheated.
For example,towing a heavy trailer during hot weather may overload the cooling system's capacity to control heat and vehicle gets overheat.

In these conditions you can turn the A/C system OFF and turn the heater on HIGH these  may help you to get the engine cool down which is overheating due to unusually hot weather or from towing a trailer.

But normally when you get Temp warning light with normal driving conditions ,then first of all stop driving.Let the engine to cool down.Please do not attempt to open the radiator cap when vehicle/engine is hot/warm.A flow of water will blow up towards you and hot steam will be released with pressure.Always let the vehicle to cool down first in these conditions.Once the engine is completely cool.Open the radiator cap and inspect the coolant level.
Basically it takes approx half an hour for vehicle to cool down.When the radiator cap is turned to open,a soda type pressure will be released.So turn the cap to open slowly,let all the pressure/steam gets released.Even though engine is cool down,the steamy pressure will be out.Yes it will not be that hot.But still let the pressure get completely released.Once the pressure is completely released remove the cap slowly.Keep your face away,if possible wear hand gloves.In case/by-chance if water flows up,you don't get harmed.

Now check the coolant level.If its low fill radiator reservoir with water.Pour water slowly.As per service manual procedure.Its said that water and Antifreeze should be added in equal proportion.Like 50/50.Half water and half Antifreeze.
But mostly you don't get antifreeze instantly,so in urgent situations,when vehicle is overheating.Just add water and when you reach your place you can add same proportion of antifreeze to the radiator reservoir.Or you can drive till the near by auto garage and get the Antifreeze filled up.

On some cases its seen that coolant is getting leaked.Or you fill the radiator cooling system with water and antifreeze with exact proportion and cooling system gets low or empty in few days or weeks.this shown that system is leaking.
As per our garage repair experience.The most common leak points are towards the radiator and heater hoses.The hoses gets loose or cracked by age and worn out.Needs to be inspected and replaced if faulty/cracked.The radiator itself gets faulty or plugged up and needs replacing.The other common issue is faulty water pump.Replacing water pump is not an easy task.Sometimes the leak is very minor or internal leak and can only be diagnosed by pressure testing the cooling system.The pressure testing tool is available at local auto parts store to buy or also at rent.

Don't ignore the temperature warning light,it can cause major damages.At out auto repair garage we have noticed such issues.The driver though it as simple low coolant issue and ignored the issue.Though he will fu\ill the system later and now the engine starts making knock knock sound while starting.Also noise problem due to detonation is noticed.If not taken care off then can cause piston, ring and head gasket damage.

Due to over heat internal parts of the engine expands.And due to this clearances gets reduced .And metal-to-metal contact occurs. Also major problems like Valve stems may gall and stick, and the pistons and camshaft might scuff or seize.

On some cases of  where vehicle has noticed Severe overheating the cylinder heads and head gaskets issues are noticed.Excessive overheating  creates tremendous thermal stress in the head(s) and block. And due to these  to cracking or complete damage is noticed. Overhead cam engines that have aluminum heads gets majorly damaged on cases of overheating.

Tailpipe came off the muffler

Tailpipe came off the muffler will this affect the gas mileage.

No it will not affect.But if muffler is out,then it will affect the mileage.

Working of muffler is as follows:----
The muffler supplies backpressure through the exhasut pipes to the engine.
That gives some of the torque your vehicle has.
If the muffler is out then that will  cause some bogging down when trying to accelerate. Not having a muffler will make your car very loud. Also, if you have no muffler, you can expect to see a slight drop in gas mileage.


ON some cases its seen that,
The joint where exhaust pipe meets the muffler gets rusted completely, and due to these the muffler falls off.
And due to this the low fuel mileage will be noticed.
In this case don't sit in the car with the engine running for very long, and keep a window at least partly open. Low fuel mileage, because the backpressure of the exhaust is reduced, compromising efficiency which is desinged around particular amount of back-pressure.


KNOW WHY MUFFLER IS USED ON VEHICLE?




The muffler's main function is to minimize noise from the engine. The exhaust manifold most likely dampens the explosions that naturally come from the piston holding chamber but as far as the function of the car (or truck) itself, it will not affect it. It may even enhance it a bit by letting it to "breathe" easier without having to pump its exhaust via the muffler.

Every cities have its own rule.It all deepens on that.In certain cities, you get caught by the police for having no muffler.As it comes under noise violations.
Exhaust emmanating from the underside of your vehicle might attract unwanted attention. Loud noise disturbs others walking and driving on the road and distract their concentration. It does get much louder as you put on more gas. As per California driving rules , a catalytic converter is mandatory and if it fell off too then you may be cited as a gross polluter.You get caught by traffic police.

These details will help.
Thanks.

Volvo car alarm keeps going off for no reason

Alarm Going off for no reason on on 2002 Volvo S60.

What can cause this problem?

There are N-number of possibilities.If your alarm is going off for seemingly no reason.Then usually that problem is the siren itself that fails, or the mass movement sensor can do it as well.

Whatever triggers your alarm (be it any sensors on the vehicle, mass movement, siren, door, etc.) are stored in the UEM. (Upper Electronic Module). The module stores this information and it can be read out on Volvo's VIDA system. So once you retrieve the error code stored in UEM it will be very easy to pinpoint the cause of problem.Without reading off the codes and what triggers the alarm, It's really impossible to know for sure what sets it off. However, the siren itself is a common failure. You will need to have the codes read off and that will pinpoint what component has failed and causing the problem.

These details will help.
Thanks.

Alarm keeps going OFF

2006 Volkswagen Transporter Security Alarm keeps going off.
Is it possible to disconnect the Alarm System?

Yes its possible to disconnect the alarm.But i dont recommend you to do so.Because that will also make you lose other power operating systems related to alarm system.

First of all check the wiring running from alarm and running to alarm.Its a minor loose connection or wires shorting somewhere.


Its not uncommon on VW vehicles causing such problems.Transporters suffer with corroded wiring under the drivers seat at the "Convenience Control Module(CCM)".These CCM controls the alarm system.On these vans are there is a function equipped  called alarm trigger store, this is where , when the alarm goes off.
The CCM will store the error codes for why the alarm has gone off and what has triggered the alarm to activate.It will be 4 digit error code. This alarm trigger store can be acessed by using a VW diag machine.
I suggest you to get the CCM scanned by VW diagnostic tool. As there are multiple things that could cause thus issue on this van.
The 3 main issues which is mostly noticed is

  • They suffer with is corroded wiring under drivers seat,
  • Interior monitoring sensors if they are fitted
  • And defective bonnet latch and wiring ,




In case to stop the Alarm system if you disconnect the CCM  then you may loose other function on the van like the central locking, electric windows, interior lights etc,.
Also if you get the alarm horn disconnected then your indicators will still flash and cause the battery to run down,and finally drain it in sometime.
So to get completely rid of the issue.I suggest to get the CCM scanned these will point you in right direction.

These details will help.
Thanks.

VW Passat will not crank?

Vehicle starts but no cranks.

2002 Volkswagen has no crank.


Two parts needs inspection,before any major testing and parts replacement.

First is battery and another is starter.

Battery testing:]

You need test light or voltmeter with you to start this simple testing procedure.

Check the power at the starter motor, you should have battery voltage on the big thick cable that is bolted to the starter and then when the key is held in the crank position there should be battery voltage on the small thin wire that has a connector attached to it, this is the first area you need to check, .

The voltage should be 12 volt.If its less then its loose terminal or bad earth or loose connection somewhere.

Starter testing:]


If you have a bad earth or the starter motor is defective.
Then to confirm the issue check for a bad earth the quickest thing will be to get a jump lead and connect one end to the metal of the engine/gearbox and connect the other end to the body on a clean point.
Now with these done try and crank car over, if its still the same the starter would appear to be defective but if it goes to start then the earth cable which goes from the body to the engine is defective, and may need to be removed and cleaned and refitted.

These details will help.
Thanks.

Volkswagen Fox Boot Lid Will not Open?

Boot Lid wont open on 2006 VW Fox


Its not uncommon issue.There are N-number of same issues noticed by others too.
The Problem:-
Rear boot lid not opening:---


SOLUTION OR TROUBLESHOOTING:--

There are a series of  problems with the rear boot lid not opening on the fox, they range from a new door lock barrel to the latch itself.

FIX:

  1. To get the boot open you  to go in through the back seat .
  2. Then remove the trim panel on the rear boot lid.
  3. Once removed you will see the latch with a rod coming off of it.
  4. As long as this rod is still attached to the latch , pull on this rod and the boot will open.
This procedure will also give you access to the boot when its open,and let you  see what is happening with the boot latch and key barrel to see which part is not operating correctly.

Also for these same problem series of tech bulletins were issued.
The repair was free on that so it may be worth getting this checked by the VW Dealer, so you dont waste money trying to replace something that doesn't need replacing.

First try the above mentioned procedure and see if the boot lid is getting open.But if something is seen cracked/worn out or broken inside then get the inspection done by dealer.Most probably it will be free repair as per the number of service bulletin released for these same fault.

These details will help.
Thanks.

Volkswagen Passat Door will Not Open?

2002 VW Passat Driver side door will not open.

PROBLEM:---
Tried both inside and outside,but door will not open.
Central locking switch tested ok.All other doors work fine.
Tries manually with key but door will not open.

TROUBLESHOOTING:---

There are few things to be tried to take care of these issue.


  1. First  try  reset procedure.For that you need to disconnect the battery for 10 mins and then re connect like rebooting a computer.Then see is the drivers door started opening. 
  2. If this does not work then operate the key fob lock and unlock while banging edge of door below door handle on drivers door.As the door latch sits there.Try and free off door latch then try and open door.Try this step few times.
  3. But if this doesn't work.Then its issue with door latch.To confirm these you need to go inside car and remove the door panel from the inside and then remove the window carrier from inside to gain access to the door latch from inside the door.

Sometimes  you may even have to break the door latch apart to get it to release from the body of the car, its quite common for the door latches to fail in the safe position and give the issues that you have.

 Its the process that professional mechanics try  and get into the car on that door.
Not always but if you have to use last option then there is a possibility that some damage may occur in the process of obtaining entry to the door.But on some cases only the parts gets slight damage.Do it slowly and gently.

These details will help.
Thanks.

TRUCK SURGES WHILE RUNNING

2003 Dodge Ram Truck 4x4 surges while driving.And check engine light came ON.

Got the truck engine module scanned.

RECEIVED MULTIPLE OBD ERROR CODES

List of received error codes:---
P0633, P0837, P0839, P2121, P2122.

Its 5.9 Cummins Engine with Standard Transmission.

NOW FROM WHERE TO START THE TROUBLESHOOTING?

Its a multiple error code issue.There are few different parts in your vehicle that needs to be inspected.
First you need to know what this codes are telling and i want to know If you have replaced the ECM(engine control module) on your vehicle or not.

OK, ECM IS NOT REPLACED?

Why i asked about ECM got replaced because of error code P0633.

The error code P0633 sets when the SKIM information hasn't been properly transferred to the ECM after replacement. If  ECM replaced then  this code set because ECM is not programmed and just replaced. This code tells you to get the New ECM programmed.

But as you mentioned above that ECM is not replaced in your vehicle then the code is set erroneously or because of an aftermarket programmer being used. This code isn't related to the problem you are having.
Its nothing to worry,but other codes are.

OK,WHAT EXACTLY THESE ALL ERROR CODES MEAN?

The other codes which you noticed are real problems.
The Error code P0837 and P0839 are both for the transfer case position sensor. These could be wiring or the sensor itself.Mostly its the sensor problem.
But this both error codes are not related to your driveability problem.Yes its related to transfer case position sensor but not related to vehicle surges while driving.

And Error codes .
P2121 and 2122 are both for the accelerator pedal position sensor (APPS).
And this error codes are definitely related to drive ability issues which are noticing.

OK,WHERE IS APPS LOCATED?


The APPS (Accelerator pedal position sensor) is  mounted to the bracket under the black plastic cover at the left front corner of the cylinder head.Its exactly where the throttle cables enter. On the back of the bracket is the APPS. These sensor tells the ECM how far the throttle is open.But if the signal from this sensor is incorrect then ECM will not control the throttle and you notice such problems.
Vehicle surges, hesitates,stalling,jerks,stumbling etc.

SO SHOULD I REPLACE ACCELERATOR PEDAL POSITION SENSOR

Before replacing this sensor i suggest to inspect the wiring.
Error codes P2121 and 2122 can be caused by a wiring problem between the sensor and ECM, or the sensor itself, or problem with the ECM.
Wiring or the ECM are possible but not common at all, although failures of the APPS is majorly noticed. What I would recommend is a visual inspection of the wiring and connection, try cleaning the Sensors plug terminals then re-insert and see if its helping.But if wiring checked ok and cleaning the Accelerator pedal position sensor connectors is not helping  then replace the APPS.That will solve the problem.

This details will help.
Thanks.

Engine turns over but will not fire or start?

2000 Dodge Ram 4x4 will not start.
When you turn the key ON,the engine turns over but truck will not start.
The fuel pump/transfer pump runs for few seconds when key is turned on,but will not start.

The Check engine light is ON.

FROM WHERE TO START TROUBLESHOOTING IN THIS CASE?

As you already mentioned that check engine light is ON.
So first step to start troubleshooting is get the error codes retrieved ,that are stored in engines computer module.
This error code will tell you what to inspect.
Get the error code scanned by scan tool.

OK,BUT I DON'T HAVE OBD TOOL TO RETRIEVE ERROR CODES?

At most of the major auto parts store,they do this error code scanning absolutely free for you.They don't charge for scanning.At autozone they do it for free.If there is any autozone parts store near you then you can get the codes scanned.

Also there is one more easy and simple method,that is manually retrieving the error codes without use of OBD scan tool code reader.

THAT'S GREAT.HOW TO RETRIEVE ERROR CODES MANUALLY?

Its very easy.The procedure is as follows.

Cycle the key from off to on three times ending with it on ( the sequence should be off-on-off-on-off-on)and watch the digital odometer display. Don't crank the starter, just off to on. The codes start with a P and have four numbers, there may be more than one stored. Once all the error codes are displayed the display will show done.
Note down the codes and list here.So further troubleshooting can be done from there.

OK.THE PROCEDURE WAS SIMPLE.THE CODES RETRIEVED ARE  P1693,P0336,P1690.

WHAT THESE CODES SAY?



P1693 sets in the powertrain control module when there is a code stored in the engine control module (ECM). If this was the only one that came up this way then there are still codes in the ECM that will need to be read with a scan tool or code reader.But in your case you also received other two error codes.So error code P1693 is not to worry error code.Its just the indication that there are more codes stored in ECM.

Now error code P0336 is for crankshaft position sensor a circuit range / performance.
Most of cases when error code P0336 is occurred,you will notice abnormal tach operation.It will bounce up and down and sometimes go dead for few seconds and come up again.


The P0336 sets when there is no crank sensor input seen by the ECM but it knows the engine is turning. Same as your case the engine is running but its not getting crank sensor signal.This can be the crank sensor or wiring but is usually the faulty crank sensor. The loss of crank sensor signal is also why the tach  drops out.

And error code P1690 is for  fuel injection pump.It says ckp sensor does not agree with the ecm ckp sensor.


The P1690 sets when the injector pump crank sensor doesn't match the other crank sensor's input. Inside the injector pump is a speed sensor that the ECM watches and compares to the crank sensor on the block. If the speeds don't match then the code sets.
So there are two sensors.One is injector pump crank sensor(also known speed sensor) and other is Crank sensor.The ECM(engine control module) receives signal from both crank senor and injection pump sensor.The reading should match,if the signal is not matching then you see error code P1690.


OK,SO WHAT PART IS TO BE REPLACED?


The error codes which you are receiving are directly and indirectly connected to issue with crank sensor.

It sounds like bad crank sensor. It would have set both of these codes and would have also prevented the injector pump from firing the injectors if the signal wasn't there. A wiring problem would be possible but not as likely, crank sensor failures on these trucks are very commonly noticed in such cases.

But before replacing the crank sensor,inspect its wiring connections properly.Test the voltage at its wiring to confirm that sensor is faulty,but wiring is not the issue.

HOW TO TEST CRANK SHAFT SENSOR WIRING?

Very simple disconnect the sensor first, then check for 5v, 5v, and ground on the three wires at the sensor with the key on. If these are ok then go ahead and replace it.If the voltage is not present,then its issue with wires getting short.Or problem with ECM.

WHERE IS CRANK SENSOR LOCATED AND HOW TO REPLACE IT?


The crank sensor is located on the left rear corner of the engine block.Its exactly behind the starter.Its like a connector,which you have to pull out.The connectors has 3 wires.First disconnect those wires and then remove the sensor. To access the crank sensor the starter has to be removed . The starter is held in with three 10mm 12 point head bolts.Once the starter is out,you can remove the sensor.

This details will help.
Thanks.

OBD codes P1521 and P0750

Poor Acceleration problem on 2006 Dodge Ram and check engine light came on.Also shifting issues noticed.
Scan test shows error code P1521 and P0750.

Is Poor Acceleration related to this error codes?
What exactly Obd error code P1521 and P0750 indicates?

Yes this error codes are related to your problem.

The error code P1521 is for incorrect engine oil type. May be you have recently got the oil replaced and refilled it with wrong oil type.Or the previously replaced oil is not got very thick and dirty.If its the case then inspect the oil condition and type and replace it with proper suggested oil as per owners manual.
The engine computer controller monitors oil pressure versus temperature to determine if the correct oil is being used, this code sets when the incorrect viscosity is detected. You may have the wrong oil in it, a thick oil additive will set the code also. As per dealer and owners manual dodge ram truck requires 5w20 and no additives or this code will set.


Now the other code which you got is P0750.
This obd error code is for the low/reverse solenoid in the solenoid pack inside the trans.The low reverse solenoid needs to be inspected. This code sets when the voltage on the circuit is incorrect for a given state. With this code set the trans is going to be in limp-in, either third gear only or third and fourth.

And due to this both error codes.
One the oil quality related and other the transmission shifting related,you will notice poor acceleration.

WHAT POSSIBILITIES TO BE CHECKED FOR P0750 ERROR CODE?



  • The solenoid has to be inspected.The solenoid shorts due to various reasons.It could be an open circuit, short to power or ground on the low/reverse solenoid driver wire anywhere between the powertrain control module and the trans.
  • On some cases it was noticed hat PCM ( power train control module) was faulty.So it could also be the powertrain control module itself. A wiring problem or the module are certainly possible but not common.
  • Or it can be connection issue at the large connector on the left side of the trans, but again that's not common.

OK,OUT OF THIS 3 POSSIBILITIES WHAT IS MOST COMMON?

The most common cause of a solenoid code is a failed solenoid, requiring solenoid pack replacement. The solenoid pack is mounted to the top of the valve body in the trans. Most likely your solenoid pack will need to be replaced to repair this concern.

So in your case first inspect oil quality and next inspect low/reverse solenoid located in transmission on top of the valve body.

This details will help.
Thanks.

Caster and Camber Alignment?

How to Adjust caster and camber Alignment on 2001 jeep grand Cherokee.



Both the Above mentioned issues will be discussed below.
As its already mentioned that problem is noticed on 2001 jeep grand Cherokee model.This model is similar to other year jeep models from year 2001 to 2005.

CAN THE CASTER AND CAMBER SETTING BE ALIGNED?

Yes of course it can be aligned.All vehicles can be aligned.Caster and camber weren't originally adjustable.
From the factory the only adjustable alignment angle on your Jeep is toe. By Toe it  refers to the left and right angle of the front wheels along with their fitting to the steering wheel.

WHAT IS DIFFERENCE BETWEEN CASTER AND CAMBER?

Both this caster and camber aligns vehicle on different regions.
Caster is the angle of the wheels front to back, camber is the amount of inward or outward lean of the wheels at the top.

OK,WHAT TOOL IS REQUIRED AND HOW TO ALIGN?


Any special tool is not required.You will require offset ball joint to start this adjusting procedure.
The steering knuckle attaches to the axle tube by a ball joint and they pivot when you turn the steering to any left/right direction. These Offset ball joints have a stud that is offset in relation to it's base, which presses into the end of the axle tube. Turning the direction of the ball joint and pressing it in at the right direction allows you to adjust caster and camber settings.

If caster or camber is out of its specification then aligning it is required.To align install an offset ball joint to correct the issue. After that is installed you will have to set toe to complete the alignment.

PROFESSIONAL GARAGE SHOP INSPECTED AND SUGGESTED NEW BALL JOINT,BECAUSE BOOT WAS MISSING?

If a ball joint is required because a boot was missing then this issue is not related to the offset ball joint that I previously mentioned, unless garage professional specifically said that they would be replacing it with an offset one. It sounds like maybe they were recommending a ball joint just because of the boot torn and not to fix the alignment.
But i suggest get the alignment issue fixed first.They are just pointing to replace ball joints but not fixing the alignment.

Also get the issue inspected by another garage store and ask them they look into installing the offset ball joints to fix the alignment issue.Also get the axle inspected it may be bent

HINT:-- If you notice  abnormally fast wear on the inside edges of the front tires? That would be a sign of a camber problem.

OK,AND WHAT ABOUT LOOSE TIE ROD END?

If a tie rod end is loose that means the steering is loose and toe cannot be correctly set.
So first get the  tie rod end replaced or repaired that should be a priority, without that done dont set toe.As it will not get aligned properly.
It is also a safety hazard and I would recommend having it repaired as soon as you can.

This details will help.
Thanks.

TIE ROD ARM DISASSEMBLY

2001 Dodge Stratus Tie rod Arm removal from Steering rod/knuckle.


How to remove Tie rod end which is connected to Steering rod?

The most of cases which we have noticed at our garage in removing  the tie rod arm from the steering arm.The the ball part on the linkage arm on the wheel is very easy to take apart,but major issue is noticed breaking the threads loose on the tie rod arm that connects to the steering rod.

Its the Nut that gets jammed.And removing this jam nut becomes frustrating.But if you have all basic tools,then its not very difficult.
Its a proper do-it-yourself procedure.

If in your case the Nut is very tight and not easy to remove.
Then the first thing is to break the jam nut loose.
For your info the jam nut is the nut threaded on to the tie rod just behind the tie rod end. You can easily see it.

Most of  new self doers first remove tie rod end from steering knuckle then remove the nut.But actually its not needed.It's much easier to break the jam nut loose if you still have the tie rod end installed in the steering knuckle.
So if you have separated the tie-rod end from knuckle then i suggest refit it.If the threads aren't damaged then go ahead and throw it back in the knuckle and start the nut. It doesn't necessarily have to be tightened all the way.Just keep it bit connected.

Once this is done then break the jam nut loose. The nut has normal right hand threads, looking at it from the wheel well you'll turn the jam nut clockwise to loosen it.And counter-clock wise to tighten it.

OK.WHAT TOOLS ARE REQUIRED TO DO THIS TASK?

Not any special tool is required.
But if you can use longer tools then its better.Because that gives you more leverage. For tie rod ends and jam nuts  use an adjustable wrench that's about 18". A longer wrench will obviously give you more leverage. If you still can't get it to break loose then you'll need to apply some heat to the nut.This will dilute the rustiness and make the nut fitting bit smooth to slide out easily.

Now once the jam nut is loose ,you can now remove tie rod end from steering knuckle.


HOW TO REMOVE TIE ROD END?

Its not very hard.
You will need gripping pliers.large wrench,pipe wrench and heating tool(not required every time)

  • Hold the tie rod stationary with some Vise Grip type pliers.
  • Then grab the flats on the tie rod end with the large adjustable wrench, wrench, pipe wrench, etc. 
  • Now to remove it turn  counterclockwise to loosen and remove it. 
  • Please don't get confused.To remove the tie rod end nut you have to turn clockwise,but to remove tie rod end itself from knuckle you have turn it counter-clock wise.
  • If the tie-rod end is tight enough to turn.There here you will often have to apply heat to get it to break loose and come off. 
NOTE: This heating is not required every time.Sometimes they will come right loose and come all the way off easily, but very often you have to heat them to get them to break loose.

This details will help.
Thanks.
