1. Loosen locknut (Figure 4, Item 2) and turn lash adjuster screw (Figure 4, Item 1) all the way in (clockwise),
then out (counterclockwise) three turns. This will remove load imposed on worm bearings by close meshing of
rack and sector teeth.
Do not turn hard against stops as damage to ball guides may result.
2. Using a socket on steering gear worm shaft (Figure 4, Item 3), turn shaft from one stop all the way to the other
carefully counting total number of turns.
3. Turn the steering gear worm shaft back half the total number back half the total number of turns to center
position and using a lb-in. torque wrench, measure pull required to keep worm shaft in motion through center
position. This should be 1.5 to 5.5 lb-in. (0.169 to 0.621 Nm).
