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 (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 12345493 (Canadian P/N 10953488) or equivalent 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 .

6. Install the ten NEW differential ring gear bolts.

Tighten the differential ring gear bolts to 95 N.m (68 lb ft).






Important: Refer to Shimming Procedures (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 (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).
