Tools Required

J 35405 Differential Preload Wrench

1. Place the outer race and the adjusting shim onto the right side bearing.
2. Place the differential assembly into the case.
3. Install the left bearing retainer. (Do not install the O-ring yet.)
4. Install the left bearing retainer bolts.

Hand tighten the left bearing retainer bolts evenly and gradually while turning the ring gear.




5. Install the right side bearing cap.
6. Hand tighten the right bearing retainer bolts evenly and gradually while turning the ring gear.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

7. Tighten the left bearing retainer (1).

Tighten
Tighten the left bearing retainer to 19 N·m (14 lb ft).





Important: The preload will change about 0.3-0.4 N·m (2.6-3.5 lb in) with each shim size.

8. Use J 35405 and a torque wrench in order to measure the preload of the side bearing.
9. Verify that the starting preload falls within the following measurement ranges:

•	For a new bearing, the torque should measure 1.0-1.6 N·m (8.7-13.9 lb in).

•	For a reused bearing, the torque should measure 0.5-0.8 N·m (4.3-6.9 lb in).

10. If the preload is not within the specifications, perform the following steps :

10.1.

Remove the differential from the case.

10.2.

Select another right adjusting shim. Refer to Differential Adjustment Shim Specifications .

11. Remove the left bearing retainer.
12. Install the O-ring.



13. Install the bearing retainer.
14. Install the bearing retainer bolts.

Tighten

•	Tighten the bearing retainer bolts to 19 N·m (14 lb ft).

•	Tighten the right bearing cap bolts to 49 N·m (36 lb ft).
