Driveline Support Assembly Assemble

Driveline Support Assembly Assemble

Rear Bearing Housing Assembly - Manual Transmission





1. If the input shaft, couplings, propeller shaft, or bearing housing assembly must be separated, the components must be marked prior to disassembly. During assembly, the components must be returned to their original position and location.

Important: Do not separate the input shaft, propeller shaft, couplings, or bearing housing assembly, unless required. These components are balanced as an assembly. Disassembly and improper reassembly of the components may cause vehicle driveline vibration.

8. Press the flexplate spindle - with bearing (1) into the housing (2). Support the inner race of the housing bearing when assembling the components.





9. Install the hub (1) onto the flexplate spindle. Align the marks on the flexplate spindle and hub for proper assembly.
10. Apply threadlock GM P/N 12345382 (Canadian P/N 10953489) or equivalent to the threads of the spindle.





11. Install the nut (1) to the flexplate spindle.
^ Tighten the spindle nut to 90 Nm (66 ft. lbs.).

Notice: Refer to Fastener Notice in Service Precautions.


Propeller Shaft Installation





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

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






2. Inspect the bushing for proper installation. A properly installed bushing will protrude 18 mm (0.708 inch) from the face of the hub.





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

4. Install the rear coupling (1), bolts (2), and washers to the propeller shaft.
^ Tighten the coupling bolts - Automatic Transmission to 70 Nm (52 ft. lbs.).
^ Tighten the coupling bolts - Manual Transmission to 90 Nm (66 ft. lbs.).

Notice: Refer to Fastener Notice in Service Precautions.

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 the coupling bolts - Automatic Transmission to 70 Nm (52 ft. lbs.).
^ Tighten the coupling bolts - Manual Transmission to 90 Nm (66 ft. lbs.).

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.






6. Install the front coupling (2), bolts (1), and washers to the propeller shaft.
^ Tighten the coupling bolts - Automatic Transmission to 70 Nm (52 ft. lbs.).
^ Tighten the coupling bolts - Manual Transmission to 90 Nm (66 ft. lbs.).





7. Install the bearing (1) onto the input shaft. Install the bearing until completely seated against the flange of the input shaft.





8. Install the snap ring (2) into the groove of the input shaft.
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 inch) between the washer and the bearing face.





10. Install the input shaft, bolts, and washers to the coupling.
^ Tighten the coupling bolts - Automatic Transmission to 70 Nm (52 ft. lbs.).
^ Tighten the coupling bolts - Manual Transmission to 90 Nm (66 ft. lbs.).





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.





12. Measure the distance (2) from the driveline tube front bellhousing flange to the bearing housing flange - automatic transmission. Record this as distance 2.
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.





18. Install the rear bearing housing bolt hole plugs (1-3).





19. Install the snap ring (1) into the driveline tube. The beveled edge of the snap ring faces the rear of the driveline tube assembly and will seat completely into the groove of the housing.

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 inch) of the recorded dimension 3.
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. Tap on the rear of the propeller shaft assembly or pull on the input shaft until the shaft has reached the proper position.

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.






21. Install the flex plate and bolts - automatic transmission.
^ Tighten the flex plate bolts to 50 Nm (37 ft. lbs.).





22. Install the clutch actuator and bolts - manual transmission.
^ Tighten the clutch actuator bolts to 12 Nm (106 inch lbs.).
