- Install the propeller shaft center bearing, if removed. Refer
to
Center Bearing Replacement
.
- Install the propeller shaft into the mounting position between
the exhaust and the underbody.
- Prepare shaft flanges for assembly:
3.1. | Clean the bushing surfaces on both the front (transmission) and
the rear (differential) flanges. |
3.2. | Apply a light coating of grease, GM P/N 12345740 or equivalent,
to the flange faces. |
- Install the propeller shaft center bearing bracket
bolts (1) through the bracket and into the body.
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.
