Worm Thrust Bearing Preload

^ Tool Required:
- J 7624 Spanner Wrench, Or Equivalent

1. Remove steering gear from vehicle.





2. Rotate stub shaft (40) back and forth to drain power steering fluid.
3. Remove adjuster lock nut (48) from housing (20).

CAUTION: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion Inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.


4. Turn adjuster nut (65) in (clockwise) using J 7624 until adjuster nut (65) and thrust support assembly (49) are firmly bottomed in housing (20). Tighten (65) to 28-31 Nm (20-23 ft. lbs.).





5. Place an index mark on housing (20) even with one of the holes in the adjuster nut (65).





6. Measure back counterclockwise 13 mm (1/2 inch) and place a second mark on housing (20).





7. Turn adjuster nut (65) counterclockwise until hole in adjuster nut (65) is aligned with the second mar on the housing (20).
8. Install coupling shield ret. and lock nut (48).
- Tighten the coupling shield ret. and lock lock nut (48) to 109 Nm (80 ft. lbs.) using a drift in a notch.
- Hold adjuster nut (65) to maintain alignment of the marks.
9. Install steering gear.
