16. Differential Case Assemble

Differential Case Assemble

^ Tools Required
- J 7079-2 Universal Driver Handle - Non-threaded
- J 44386 Input/Output Bearing Installer





1. Clean all parts in a suitable solution before assembling.

2. Important:
^ Refer to Shimming Procedures before assembling the differential case.
^ Lubricate the bearing inner and outer race surface before assembly.

Install the following parts into the differential case (7):
^ The pinion gears (3)
^ The pinion gear thrust washers (2)
^ The side gears (5)
^ The side gear thrust washers (4)
^ The pinion shaft (6)
^ NEW snap rings (1)





3. Important:
Apply even pressure to the vehicle speed sensor (VSS) ring during installation.

Install the vehicle speed sensor (VSS) ring onto the differential case.





4. Apply GM P/N 12345493 (Canadian P/N 10953488) or equivalent to the differential ring gear bolts.

5. Important:
The machined surface on the differential ring gear faces the differential case.

Install the differential ring gear onto the differential case.

6. Notice:
Refer to Fastener Notice in Service Precautions.

Install the ten NEW differential ring gear bolts.
Tighten the differential ring gear bolts to 95 Nm (68 ft. lbs.).





7. Important:
Refer to Shimming Procedures before installing the left differential side bearing.

Install a NEW left differential side bearing and shim onto the differential case using the J 44386 and the J 7079-2.





8. Important:
Refer to Shimming Procedures before installing the right differential side bearing.

Install a NEW right differential side bearing and shim onto the differential case using the J 44386 (2) and the J 7079-2 (1).
