20. Remove the steering shaft assembly (2) from the steering column tilt head assembly (1).





21. Important: Mark the race and upper shaft assembly and the lower shaft assembly before disassembly. Failure to assemble the race and upper shaft assembly and the lower shaft assembly correctly will cause the steering wheel to be turned 180 degrees.

Tilt the race and upper shaft assembly (1) 90 degrees to the lower shaft assembly (2).
22. Disengage the race and upper shaft assembly (1) from the lower shaft assembly (2).





23. Insert the race and upper shaft assembly (1) into J 41688.
24. Insert J 41688 into a vise.
25. Rotate the driver 90 degrees in the counterclockwise direction in order to disengage the centering sphere from the race and upper shaft assembly.
26. Remove the race and upper shaft assembly (1) from J 41688.
27. Remove the shaft preload spring and the centering sphere from J 41688.
28. If necessary, discard the old centering sphere and the old shaft preload spring.





29. Remove the 4 TORX head screws (2) from the steering column support assembly (1).
30. Discard the 4 TORX head screws.
31. Remove the steering column support assembly (1) from the steering column jacket assembly.

Installation Procedure





1. Notice: Refer to Fastener Notice in Service Precautions.

Important: The steering column support assembly must be replaced if it has been staked 3 times.

Attach the steering column support assembly (1) to the steering column jacket assembly (3) with the 4 TORX head screws (2).
^ Tighten the screws to 17 Nm (13 ft. lbs.).





2. Lubricate the centering sphere (1) with GM P/N 12345718 (Canadian P/N 10953516).
3. Insert the centering sphere (1) and the joint preload spring (2) into J 41688.
4. Place the base of J 41688 into a vise.





5. Compress the centering sphere and the joint preload spring.
6. Rotate the driver 90 degrees in the clockwise direction until the arms lock in place.





7. Attach the race and upper shaft assembly (1) to J 41688.
8. Rotate the race and upper shaft assembly (1) downward 90 degrees until the centering sphere is locked in place.





9. Remove the race and upper shaft assembly and J 41688 from the vise.
10. Disassemble J 41688 by separating the base.
11. Remove the race and upper shaft assembly, which is now attached to the centering sphere, from J 41688.





12. Lubricate the exposed steering shaft with GM P/N 12345718 (Canadian P/N 10953516).
13. Align the lower steering shaft assembly to the race and upper shaft assembly by using the alignment marks.
14. Tilt the lower steering shaft assembly at 90 degrees to the race and upper shaft assembly.
15. Install the lower steering shaft assembly onto the race and upper shaft assembly.





16. Install the steering shaft assembly (2) into the steering column tilt head assembly (1).





17. Install the steering shaft assembly with the tilt head assembly (1) into the steering column jacket assembly (2).
18. Maneuver the tilt lever and push the tilt head assembly (1) up towards the steering column in order to lock the steering wheel lock shoes in place.





19. Lubricate the pivot pins (1) with GM P/N 12346293 (Canadian P/N 992723).
20. Firmly seat each pivot pin (1) into the tilt head assembly.
21. Stake the steering column support assembly in the 3 locations around each pivot pin.





22. Install the adapter and bearing assembly (1) onto the steering column jacket assembly by performing this procedure:
1. Align the tab on the adapter and bearing assembly (1) with the slot in the steering column jacket assembly.
2. Push the adapter and bearing assembly (1) onto the steering shaft assembly until the tab snaps into the slot.
23. Install the shaft seal retainer (2) onto the adapter and bearing assembly (1).
1. Align the slots of the shaft seal retainer (2) to the ribs of the adapter and bearing assembly (1).
2. Push the shaft seal retainer (2) onto the steering shaft assembly so that the retainer (2) contacts the adapter and bearing assembly (1).
24. Install the steering shaft seal (3) onto the steering shaft assembly.
25. Install the inner boot seal (4) onto the steering shaft assembly.
26. Install the linear shift assembly.





27. Install the A/T shift lock control.
28. Put the shift lever clevis into the NEUTRAL position.





29. Adjust the A/T shift lock control by performing these steps:
1. Pull out the tab (1) on the adjuster block (2) side of the A/T shift lock control.
2. Press on the adjuster block (2) to compress the internal adjuster spring which disengages the adjuster teeth.
3. Slide the adjuster block (2) as far away from the solenoid as possible.
4. Push inward on the tab (1) in order to lock the adjuster block (2) in place.
30. Inspect the A/T shift lock control for these items:
1. The A/T shift lock control must lock the shift lever clevis when the shift lever clevis is put into the PARK position. Once the steering column is installed in the vehicle, the gear shift lever must remain in the PARK position unless the brake pedal is depressed.
2. The solenoid will be energized.
31. Adjust the A/T shift lock control if needed.





32. Install the turn signal and multifunction switch assembly onto the steering column tilt head assembly.

Caution: Refer to SIR Inflator Module Coil Caution in Service Precautions.

Important: Rest the electrical contact of the turn signal and multifunction switch assembly on the turn signal cancel cam assembly.
