Side Bearing Preload Adjustment Procedure

^ Tools Required:
- J 8001 Dial Indicator Set
- J 37760 Spanner Wrench





1. Loosen the right differential side bearing adjuster using J 37760 until it no longer makes contact with the right differential side bearing race.
2. Tighten the left differential side bearing adjuster using J 37760 until the ring gear is fully engaged with the pinion gear (0.000 backlash).

Inspect
A. The right adjuster making sure it is not making contact with the right side bearing race.
B. Pinion gear for binding by grasping the pinion flange and rotating the pinion gear several times.





C. Install a J 8001 on the differential carrier between the center of each side bearing cap to measure case spread.
D. Tighten the right adjuster using J 37760 until the adjuster makes contact with the right side bearing race.
E. Rotate the J 8001 adjustable face until indicator needle reads 0.

Adjust
- Differential side bearing preload by tightening the right adjuster using J 37760 until the J 8001 reads 0.0508 to 0.1524 mm (0.002 to 0.006 inch). This specification indicates the amount of case spread between the centers of both side bearing caps.
