REMOVAL & INSTALLATION



See Figures 1, 2 and 3

1971 Models
  1. Raise and support the front end on jackstands.
  2. Remove the cotter pin and nut and disconnect the right tie rod section from the bell crank.
  3. Remove the cotter pins and nuts, and, using a puller or separator, disconnect the outer ends from the knuckles.
  4. Where applicable, the left and right tie rod sections can now be separated.
  5. The tie rod ends can be removed by loosening the clamps and unscrewing the ends. Before unscrewing the ends, note the exact number of threads visible, as an installation reference.
  6. All seals that show any sign of wear should be replaced. New tie rod ends should be installed if the old ones show any play or roughness of movement.
  7. Install the new tie rod ends, leaving the exact number of threads exposed, as previously noted. Torque all nuts to 38-42 ft. lbs.

Steering Column


REMOVAL & INSTALLATION



All Models
  1. Disconnect the battery ground.
  2. Remove the column cover plate at the floorboards.
  3. Remove the column-to-dash lower bezel.
  4. On models with automatic transmission, disconnect the shift rod at the column. On models with air conditioning, it will be necessary to remove the left side air conditioning duct.
  5. Remove the column-to-dash bracket and lower the column.

Later models have breakaway capsules in the bracket. Remove the bracket and put it in a safe place to avoid damage to the capsules.

  1. Disconnect any wiring attached to column components.
  2. Remove the steering column-to-gear shaft coupling and pull the column out of the Jeep.
  3. On models with energy absorbing columns, it is extremely important that only specified fasteners be used. Fasteners which are not of the exact length or hardness may impair the energy absorbing action of the column. Bolts securing the column mounting bracket to the dash must be torqued exactly.
  4. Connect the column to the gear shaft and tighten the coupling pinch bolt to 45 ft. lbs.
  5. Connect all wiring. If you have Cruise Command, connect the white wire first, then the black one.
  6. Install the toe plates, but don't fully tighten the fasteners.
  7. Install the bracket on the column and torque the bolts to 20 ft. lbs.
  8. Align the bracket and dash and loosely install the mounting bolts.
  9. While applying a constant upward pressure on the column, torque the bracket-to-dash bolts to 20 ft. lbs.
  10. Torque the toe plate bolts to 10 ft. lbs.
  11. Install the bezel.
  12. Connect the transmission linkage and check its operation.
