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.

in the original direction.
2. Remove the worm bearing adjuster locking ring
and the worm bearing adjuster.
