For 1990-2009 cars

### Removal Procedure

1. Place the transmission in neutral.
2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
3. Remove the heatshield nuts.
4. Remove the heatshields.
5. Remove the bolts (1) from the propeller shaft center bearing bracket at the underbody.
6. Reference mark the front of the propeller shaft at the transmission coupling.
7. Remove the propeller shaft from the transmission coupling:

7.1. | Remove the coupling nuts.

7.2. | Remove the coupling bolts.

7.3. | Slide the front half of the shaft rearward in order to clear the coupling about 25 mm (1 in).

7.4. | Lower the shaft.

8. Reference mark the rear of the propeller shaft at the differential coupling.
9. Remove the propeller shaft from the differential coupling:

9.1. | Remove the coupling nuts.

9.2. | Remove the coupling bolts.

9.3. | Slide the rear of the propeller shaft forward in order to clear the coupling about 25 mm (1 in).

9.4. | Lower the shaft.

10. Slide the propeller shaft between the exhaust and the underbody in order to remove the propeller without removing the exhaust system.
11. Remove the propeller shaft center bearing, if necessary. Refer to Center Bearing Replacement .

### Installation Procedure

1. Install the propeller shaft center bearing, if removed. Refer to Center Bearing Replacement .
2. Install the propeller shaft into the mounting position between the exhaust and the underbody.
3. 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.

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.

4. Install the propeller shaft center bearing bracket bolts (1) through the bracket and into the body.

Tighten
Tighten the bolts to 20 N·m (15 lb ft).

5. Align the reference marks on the propeller shaft to the differential coupling.
6. Install the propeller shaft to the rear propeller shaft coupling.
7. Install the rear propeller shaft coupling bolts.
8. Install the rear propeller shaft coupling nuts.

Tighten
Tighten the bolts and nuts to 95 N·m (70 lb ft).

9. Align the reference marks on the propeller shaft to the transmission coupling.
10. Install the propeller shaft to the transmission coupling.
11. Install the front coupling bolts.
12. Install the front coupling nuts.

Tighten
Tighten the bolts and nuts to 95 N·m (70 lb ft).

13. Install the heatshields.
14. Install the heatshield nuts.

Tighten
Tighten the nuts to 2 N·m (18 lb in).
