REPAIR THE STEERING GEAR

Disassembly

NOTE: The steering gear must be removed from the vehicle for this

procedure. Refer to

Replace the Steering Gear

section for

information regarding removing the steering gear.

NOTE: The steering gear is packed with grease. Only perform maintenance

on the steering gear in an area that will contain any grease that
may spill out of the steering gear when it is disassembled.

Refer to the illustration at the end of this section for a blown up view of the steering gear assembly.

1. Center the steering gear.

A. Turn the steering shaft all of the way in one direction.

B. While counting the rotation, turn the steering shaft all of the way in the opposite direction.

C. Turn the steering shaft 1/2 the number of turns in the original direction.

2. Remove the worm bearing adjuster locking ring and

the worm bearing adjuster.

3. Remove the side cover/pitman shaft assembly by

removing the three side cover bolts and then pulling
the assembly out of the housing.

NOTE: The side cover/pitman shaft assembly

normally does not have to be
disassembled.
