INSTALL OR CONNECT

NOTICE: 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.

- Lubricate all parts with axle lubricant.

1. Pinion gears and pinion gear thrust washers to the pinion cross shaft spider.
2. Differential side gears and side gear thrust washers to the differential case halves in their original locations.
3. Pinion cross shaft spider to the differential.
4. Case halves.
A. Align the scribe marks on the case halves.
B. Check that the mating surfaces of the differential case and the ring gear are clean and burr free.





5. Ring gear to the differential.
A. Thread two left-hand threaded studs into the ring gear on opposite sides.
B. Place the ring gear onto the case, and align the holes in the case with the studs.
C. Press the ring gear onto the case far enough to start the bolts using J 8107 to protect the differential from the press ram.
6. Ring gear bolts.
- Tighten:
A. The ring gear bolts alternately in stages gradually pulling the ring gear onto the differential case.
B. The ring gear bolts in sequence to 163 Nm (120 ft. lbs.).





7. Differential side bearings using J 24429 and J 8092.
A. Place J 8107 into the differential on the side opposite of bearing installation to protect the differential case.
B. Drive the bearing onto the case using J 24429 and J 8092.
8. Differential case to the axle housing. Refer to SIDE BEARING PRELOAD ADJUSTMENT.
