The steering gear transfers Rack and Pinionthe rotary motion of the steering wheel to a linear motion used to steer the front wheels. Two types of steering gear are in use today, the standard gear box and the rack and pinion. The standard gear box uses a worm gear that is rotated by the steering wheel to move the pitman shaft. The worm gear contains spiral cut grooves that mesh with a sector gear at the top of the pitman shaft. The spiral action of the worm gear causes the pitman shaft to move the steering linkage in a linear motion. Power steering is achieved by using hydraulic pressure to assist in the rotation of the worm gear.

Rack and pinion steering provides a much simpler method of converting the circular motion of the steering wheel to linear motion for steering. The steering column attaches to the top of the rack and pinion unit and rotates the pinion gear. The pinion gear actuates the rack, which is a simple straight shaft with teeth cut in the top. The rack will simply move back and forth, in a linear motion, in response to the pinion gear. The only steering linkage used is tie rods to indirectly link the rack gear to the steering knuckle. Vehicles with power rack and pinion steering use hydraulic pressure to assist in rotating the pinion gear.

------------

To Install a New Steering Rack :--


  • Lock the steering wheel straight ahead and drain the steering fluid. Remove the battery cables, front wheels and steering column coupler and front emissions vapor canister. Disconnect the hose at the steering cooler and let it drain before plugging it.

  • Uncouple the tie rod ends and remove the lower control arm rear bushing bolts. Disconnect the crossmember reinforcement. Unhook the power steering lines and remove the mounting fasteners from the steering gear. Disconnect the intermediate shaft coupler and remove the gear assembly from the undercarriage.

  • Mount the new steering rack and then partially insert the shaft coupler rolling pin into the intermediate shaft coupler. Tap it into the coupler with a hammer, then attach the coupler to the gear shaft. Insert the installer tool through the roll pin center and secure with the knurled nut. Keep the threaded rod stationary and pull the pin into the coupler by turning the knurled nut.

  • Reverse-assemble the remaining parts. Tighten the 14mm steering gear fasteners to 135 foot pounds, the steering line connections to 25 foot pounds, M14 crossmember bolts to 113 foot pounds and M12 to 75 foot pounds, the control arm bushing bolts to 45 foot pounds and the tie rod nuts to 55 foot pounds. Fasten the power steering cooling hose with its clamp.

  • Replace the front wheels and connect the column shaft coupler. Apply 21 foot pounds of torque to the pinch bolt. Reconnect the battery cables.

  • Fill the steering system and bleed it. Check to make sure you lines aren't leaking and your wheels are aligned properly.


  • Depending on your Voyager's options, you may also need to remove the front emissions canister, power steering cooler-to-cradle bolts, bolts connecting the leak detection pump to the cradle crossmember and all wheel drive power transfer unit.

    Keep track of the size and locations of the bolts as you remove them. The many bolts and sizes are easy to confuse.
