26. Discard the 4 torx head screws.
27. Remove the steering column support assembly (1) from the steering column jacket assembly.

Assembly Procedure

Tools Required

- J 41688 Centering Sphere Installer Tool

Important: Replace the steering column support assembly (1) if the steering column support assembly (1) has been staked 3 times.




1. Attach the steering column support assembly (1) to the steering column jacket assembly (3) with 4 torx head screws (2).
Tighten
Tighten the 4 torx screws to 17 N.m (13 lb ft).




2. Lubricate the centering sphere (1) with lithium grease.
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. Apply lithium grease to the exposed steering shaft.
13. Align the lower steering shaft assembly (2) to the race and upper shaft assembly (1) by using the marks.
14. Tilt the lower steering shaft assembly (2) at 90 degrees to the race and upper shaft assembly (1).
15. Install the lower steering shaft assembly (2) onto the race and upper shaft assembly (1).




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




17. Install the steering shaft assembly with the steering column tilt head assembly (1) into the steering column in order jacket assembly (2).
18. Maneuver the tilt lever push the steering column 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 lithium grease.
20. Firmly seat each pivot pin (1) into the steering column tilt head assembly.
21. Stake the steering column support assembly in 3 locations around each pivot pin.




22. Install the adapter and bearing assembly (1) onto the steering column jacket assembly by performing the following steps.
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 shaft seal 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 onto the steering column support assembly.
27. Secure the linear shift assembly to the steering column assembly with the 3 flat head tapping screws.
Move the linear shift assembly out of the park position to install the lower socket tapping screw.
Tighten
Tighten the 3 flat head tapping screws to 10 N.m (89 lb in).




28. Install the electrical BTSI actuator.
29. Put the shift lever clevis into the neutral position.




30. Adjust the electrical BTSI actuator by performing the following steps.
1. Pull out the tab (1) on the adjuster block (2) side of the electrical BTSI actuator.
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.
31. Inspect the electrical BTSI actuator for the following items.
1. The electrical BTSI actuator 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.
32. Readjust the electrical BTSI actuator if needed.




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

Important: Be sure that the electrical contact of the turn signal and multifunction switch assembly (2) rests on the turn signal cancel cam assembly.
