CTS-V V8-6.0L VIN U (2006)
12. Inspect the propeller shaft coupler for the following conditions:
^
Splitting of the coupler
^
Deep cracking. Minor superficial cracking of the coupler is acceptable.
^
Looseness at the propeller shaft mounting bolts
^
Distorted or missing mounting bolt bushings
13. If any of the above conditions are found, the propeller shaft requires replacement.
Installation Procedure
1. Using a clean shop towel, clean the following:
^
Differential flange centering pin
^
Transmission flange centering pin
^
Front propeller shaft centering bushing
^
Rear propeller shaft centering bushing
2. Apply a small amount of lubricant GM P/N 1051344 (Canadian P/N 993037), or equivalent, to the front and rear propeller shaft centering
bushings.
3. Inspect the propeller shaft-to-flange nuts (4), bolts (6), and washers (5). Replace if damaged or worn. Install the rear propeller shaft coupler (2) to
the differential flange (3).
4. Rest the support bearing on the support device.
5. 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.
6. Install the propeller shaft coupler-to-differential flange washers (5) to the propeller shaft coupler-to-differential flange bolts (6).
7. Install the propeller shaft coupler-to-differential flange bolts (6) and washers (5) to the propeller shaft coupler (2) and differential flange (3).
8. Install the propeller shaft coupler-to-differential flange nuts (4).
Tighten the propeller shaft coupler-to-differential flange bolts and nuts to 85 Nm (63 ft. lbs.).
Notice: Refer to Fastener Notice in Service Precautions.
