Propeller Shaft Installation

Important:  Install the propeller shaft bushing into hub with the smaller opening of the bushing positioned away from the flange.

1. Install a NEW bushing (1) into the automatic transmission propeller shaft, if required.

3. Apply threadlock GM P/N 12345382 (Canadian P/N 10953489) or equivalent to the threads of the coupling bolts.
   NOTE: Refer to FASTENER NOTICE .

   Important:  If the coupling orientation mark has been lost during the cleaning or disassembly process, the coupling MUST be installed with the directional arrow pointed toward the flange to which it mounts.

4. Install the rear coupling (1), bolts (2), and washers to the propeller shaft.

   Tighten 

   • Tighten the coupling bolts - Automatic Transmission to 70 N.m (52 lb ft).
   • Tighten the coupling bolts - Manual Transmission to 90 N.m (66 lb ft).

   Important:  If the coupling orientation mark has been lost during the cleaning or disassembly process, the coupling MUST be installed with the directional arrow pointed toward the flange to which it mounts.

5. Install the rear bearing housing assembly, bolts, and washers to the rear coupling.

   Tighten 

   • Tighten the coupling bolts - Automatic Transmission to 70 N.m (52 lb ft).
   • Tighten the coupling bolts - Manual Transmission to 90 N.m (66 lb ft).
6. Install the front coupling (2), bolts (1), and washers to the propeller shaft.

   Tighten 

   • Tighten the coupling bolts - Automatic Transmission to 70 N.m (52 lb ft).
   • Tighten the coupling bolts - Manual Transmission to 90 N.m (66 lb ft).

9. Install a NEW slinger washer (1) onto the input shaft.

   A properly installed slinger washer will have a gap of 1.5-2.5 mm (0.050-0.098 in) between the washer and the bearing face.

10. Install the input shaft, bolts, and washers to the coupling.

    Tighten 

    • Tighten the coupling bolts - Automatic Transmission to 70 N.m (52 lb ft).
    • Tighten the coupling bolts - Manual Transmission to 90 N.m (66 lb ft).
11. Measure the distance (1) from the end of the input shaft to the flange on the bearing housing - automatic transmission. Record the amount as distance 1.

13. Subtract the distance 2 from distance 1.
14. Record the computation as distance 3.
15. Lubricate the NEW driveline tube O-ring (1) with clean engine oil.
16. Install the O-ring into the front of the driveline tube.

17. Install the propeller shaft assembly into the driveline tube.

    During installation, lift the front of the input shaft to avoid damage to the slinger washer. Using a punch, tap evenly on the flat flange area of the rear bearing housing and install the assembly completely into the tube.

    Important:  The propeller shaft assembly must be checked for proper installation into the driveline tube - automatic transmission. When the propeller shaft assembly is installed into the driveline tube, the couplings may compress and not properly position the input shaft.

20. Measure the distance from the end of the input shaft to the driveline tube front bell housing flange - automatic transmission.

    The actual distance must be equal to or within 2 mm (0.079 in) of the recorded dimension 3.

    1. 20.1. If the actual distance is not within specifications, use a heat gun and heat the outside of the driveline support tube at the front bearing location.
    2. 20.2. Tap on the rear of the propeller shaft assembly or pull on the input shaft until the shaft has reached the proper position.
21. Install the flex plate and bolts - automatic transmission.

    Tighten 

    Tighten the flex plate bolts to 50 N.m (37 lb ft).

22. Install the clutch actuator and bolts - manual transmission.

    Tighten 

    Tighten the clutch actuator bolts to 12 N.m (106 lb in).
