Propeller Shaft Replacement (CTS-V)

Notice: The propeller shaft must be supported during removal and/or installation so that the CV joint does not articulate more than 8 degrees. Allowing the propeller shaft to articulate greater than 8 degrees could cause damage to the CV boot. Damage to boot could lead to contamination or loss of lubrication which could lead to CV joint damage.

Removal Procedure

1. Raise and support the vehicle.
2. Remove the exhaust system.
3. Using a suitable jack, support the propeller shaft close to the support bearing.
4. Using a suitable jack, and/or heavy mechanical wire support the front propeller shaft close to the rear constant velocity (CV) joint.





5. Remove the bolts (1) securing the support bearing to the vehicle underbody.





6. Reference mark the location of the propeller shaft CV joint to the differential flange.
7. Remove the propeller shaft CV joint-to-differential flange bolts.





8. Remove the propeller shaft coupler-to-transmission flange bolts (5), nuts (1) and washers (4).

Important: Remove only the propeller shaft coupler-to-transmission flange bolts. Do NOT remove the coupler from the propeller shaft.

9. Move the propeller shaft toward the front of the vehicle in order to release the propeller shaft CV joint from the differential flange.
10. While holding the propeller shaft, lower the support device under the propeller shaft.
11. Move the propeller shaft rearward to release the coupler from the transmission flange.
12. Remove the propeller shaft from the vehicle.
13. Inspect the propeller shaft coupler for the following conditions:
^ Splitting of the coupler
^ Deep cracking. Minor superficial cracking of the coupler is acceptable
^ Distorted or missing mounting bolt bushings

14. If any of the above conditions are found, the propeller shaft requires replacement.
15. If the propeller shaft coupler shows signs of heat related damage check for the following:
^ Exhaust system alignment or wear
^ Powertrain mount alignment or wear

16. Inspect the propeller shaft CV joint assembly for the following conditions:
^ Grease leaking from the CV joint
^ Damage to the CV joint
^ Damage to the CV joint boot

17. If any of the above conditions are found, the propeller shaft requires replacement.
18. Inspect the propeller shaft-to-flange nuts, bolts, and washers. Replace if damaged or worn.

Installation Procedure
1. Using a clean shop cloth clean the following:
^ Transmission flange centering pin
^ Propeller shaft centering bushing

2. Using a suitable jack support the propeller shaft close to the support bearing.

Important: The propeller shaft flange bolts must be installed toward the flanges.

3. Using a suitable jack, and/or heavy mechanical wire support the front propeller shaft close to the rear CV joint.
4. Apply a small amount of lubricant GM P/N 1051344 (Canadian P/N 993037), or equivalent, to the propeller shaft centering bushing.





5. Install the front propeller shaft coupler (3) to the transmission flange (2).
6. Push the propeller shaft (6) to the front of the vehicle and install the propeller shaft to the differential flange.

7. Thoroughly clean the threads using denatured alcohol, or equivalent, and allow to dry. Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488), or equivalent, to the propeller shaft-to-flange bolt. Ensure that there are no gaps in the threadlocker along the length of the filled area of the bolt. Allow the threadlocker to cure approximately 10 minutes before installation.

Important: If reusing the propeller shaft-to-flange nuts and bolts, to ensure proper adhesion and fastener retention, the threads must be free of debris prior to the application of the threadlocker.

8. Install the propeller shaft coupler-to-differential flange washers (4) to the propeller shaft coupler-to-transmission flange bolts (1).
9. Install the propeller shaft coupler-to-transmission flange bolts (5) and washers (4) to the differential flange (2) and propeller shaft coupler (3).

10. Install the propeller shaft coupler-to-differential flange nuts (1).
Tighten the bolts to 85 Nm (63 ft. lbs.).

Notice: Refer to Fastener Notice in Service Precautions.


11. Thoroughly clean the threads using denatured alcohol, or equivalent, and allow to dry. Apply Threadlocker GM P/N 12345493 (Canadian P/N 10953488), or equivalent, to the propeller shaft-to-flange bolt. Ensure that there are no gaps in the threadlocker along the length of the filled area of the bolt. Allow the threadlocker to cure approximately 10 minutes before installation.

Important: If reusing the propeller shaft-to-flange nuts and bolts, to ensure proper adhesion and fastener retention, the threads must be free of debris prior to the application of the threadlocker.






12. Install the propeller shaft CV joint-to-differential flange bolts.
Tighten the bolts in sequence (1?6) to 60 Nm (44 ft. lbs.).





13. Raise the support device in order to hold the support bearing in position.
14. Install the center support bearing bolts (1) to the vehicle underbody.
Tighten the nuts to 50 Nm (37 ft. lbs.).
15. Remove the support devices from the propeller shaft.
16. Install the exhaust system.
17. Lower the vehicle.
