- Clean all parts in a suitable solution
before assembling.
Important:
| • | Lubricate the bearing inner and outer race surface before assembly. |
- Install the following parts into the differential case (7):
| • | The pinion gear thrust washers (2) |
| • | The side gear thrust washers (4) |
Important: Apply even pressure to the vehicle speed sensor (VSS) ring during installation.
- Install the vehicle speed sensor (VSS) ring onto the differential case.
- Apply GM P/N 12345493 (Canadian P/N 10953488)
or equivalent to the differential ring gear bolts unless pre-coated.
Important: The machined surface on the differential ring gear faces the differential case.
- Install the differential ring gear onto the differential case.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the ten NEW differential ring gear bolts.
Tighten
Tighten the differential ring gear bolts to 95 N·m (68 lb ft).
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
.
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).
