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.

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

2. 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)





Important: Apply even pressure to the Vehicle Speed Sensor (VSS) ring during installation.

3. Install the Vehicle Speed Sensor (VSS) ring onto the differential case.





4. Apply GM P/N United States 12345493, GM P/N Canada 10953488 to the differential ring gear bolts.

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

5. Install the differential ring gear onto the differential case.

Notice: Refer to Fastener Notice in Service Precautions.

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





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

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





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

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