Assembly Procedure

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 GMC Sierra, 2002 Chevrolet Tahoe, and 2002 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.

Lubricate the pinion and side gears using axle lubricant. Use the proper fluid. Refer to Figure.
Install the differential side gears and thrust washers into the differential case.
If the same differential side gears and the thrust washers are being used, install the side gears and the thrust washers to their original locations.

Fig 1: Differential Side Gears & Thrust Washers
Install the differential pinion gears by performing the following steps:
1. Position one pinion gear between the differential side gears.
2. Position the second pinion gear between the differential side gear directly opposite of the first gear.
3. Rotate the differential side gears until the pinion gears are directly opposite the opening in the differential case.
Fig 2: Differential Pinion Gears & Thrust Washers
Install the thrust washers.
Rotate the pinion gears toward the differential case opening in order to permit the sliding in of the thrust washers.
Install the pinion gear shaft.

Fig 3: Installing Pinion Shaft
Install the new pinion gear shaft lock pin using a hammer and a brass drift.
Important: The mating surface of the ring gear and the differential case must be clean and free of burrs before installing the ring gear.
Install the ring gear onto the differential case.
Important: The ring gear bolts have left-hand threads.

Install the new ring gear bolts.
Hand start each bolt to ensure that the ring gear is properly installed to the differential case.

NOTE: Refer to FASTENER NOTICE .

Fig 5: Ring Gear Bolts
Tighten the ring gear bolts. Tighten the ring gear bolts alternately and in stages, gradually pulling the ring gear onto the differential case.
Tighten

Tighten the ring gear bolts in sequence to 120 N.m (88 lb ft).
Install the differential side bearings by performing the following steps:
1. In order to protect the differential case, install the J 8107-2 in the case on the side opposite the bearing installation.
2. Install the J 22761 (2) and the J 8092 (1) onto the differential case bearing as shown.
3. Drive the differential case bearing onto the case using the J 22761 and the J 8092 .
