9. Remove the inner race seat and the inner race.





10. Pull the tilt lever on the column housing assembly and tilt the column all the way up.





11. Insert a Phillips screwdriver into the square opening at the bottom of the spring retainer. Push and turn left to release the spring retainer and the wheel-tilt spring.
12. Remove the spring retainer and the wheel-tilt spring.





13. Remove the two pivot pins using the pivot pin remover J-21854-01.





14. Place the lock cylinder in the ACC position.
15. Pull the tilt lever to release the column housing. Remove the column housing and the steering shaft from the housing support.
16. Remove the shear bolts, the shear bolt washers, and the ignition switch housing from the steering column housing as follows:
16.1 Use a metal punch to start the drill head.





16.2 Drill off the head of the shear bolts down to the steel shear bolt washers with a 6.5 mm (1/4 inch) drill bit.
16.3 Separate the washers and the ignition switch housing from the column housing.
16.4 Remove the threaded end of the shear bolts from the ignition switch housing with locking pliers.

Important: After drilling and removing the threaded end of the shear bolts, all the metal shavings must be cleaned from all the parts.





17. Remove the lock cylinder from the ignition switch housing by pushing the lock cylinder release tab.





18. Remove the ignition switch retaining screw and remove the ignition switch assembly.





19. Remove the steering shaft assembly from the support housing.





20. Remove the tilt bumpers with a pair of pliers.





21. Remove the support screws and remove the support housing from the jacket assembly.

Disassembly Procedure for the Steering Shaft Assembly

Important: Prior to separating the upper shaft from the lower shaft, note the relationship of the upper shaft, with the lock bolt slot at the 12 o'clock position, to the lower shaft pinch bolt groove at the 7 o'clock position. Refer to this orientation for proper assembly.





1. Position the upper shaft 90 degrees to the lower shaft and separate the two parts.





2. Rotate the centering sphere 90 degrees and remove it from the upper shaft.





3. Separate the sphere halves and remove the joint preload spring.

Assembly Procedure for the Steering Shaft Assembly





1. Lubricate the centering sphere halves and the joint preload spring with lithium grease.
2. Place the joint preload spring between the sphere halves with the ends of the spring in the notches.
3. Lubricate the sphere end of the upper shaft with lithium grease.





4. Place the sphere into the upper shaft and rotate the sphere 90 degrees.
5. Lubricate the sphere end of the lower shaft with lithium grease.

Important: To insure proper operation, the upper shaft and the lower shaft must be aligned correctly when they are connected.





6. Place the lock bolt slot on the upper shaft at the 12 o'clock position.
7. Place the pinch bolt groove near the end of the lower shaft at the 7 o'clock position.
8. Connect the upper shaft to the lower shaft.

Assembly Procedure

Important: All fasteners in the following steps must be seated firmly before being tightened to specifications.





1. Connect the support housing to the jacket assembly with the support screws.
Tighten the support housing screws to 16 Nm (12 ft. lbs.).





2. Connect the tilt bumpers to the support housing and snap them in place.





3. Slide the steering shaft assembly into the support housing.





4. Lubricate both bearings in the column housing with lithium grease. Slide the column housing onto the shaft assembly and the support housing.





5. Lubricate the pivot pins with lithium grease and slide the pins into the housing until the pins are bottomed. Tap the pivot pins in place.

Important: The pivot pins must be staked to the column housing after installation. Stake each pin at three equally spaced locations.





6. Pull the tilt lever on the column housing and tilt the column all the way up.
7. Lubricate the tilt spring with lithium grease.





8. Install the tilt spring and the spring retainer. Be sure the spring engages the locating tab on the support housing. Insert a Phillips screwdriver into the square opening in the spring retainer, push down, and turn right to lock it in place.





9. Install the ignition switch with the ignition switch retaining screw. Connect the wiring.

10. Important: To ensure that the tab on the lock-cylinder shaft and the slotted opening on the ignition switch are in alignment, the lock cylinder must be in the ACC position prior to installation.





11. Install the lock cylinder into the ignition switch housing.





12. Attach the ignition switch housing to the column housing with the shear bolt washers and the shear bolts.
Tighten the ignition switch housing shear bolts until the bolt head separates from the body, approximately 11 Nm (97 inch lbs.).
13. Place lock cylinder in the LOCK position and remove the key.
14. Rotate the steering shaft assembly until the lock bolt engages and locks the steering shaft in position.
15. Install the inner race and the inner race seat.





16. Install the upper bearing spring and the spring retainer.





17. Compress the upper bearing spring and the spring retainer with the lock plate adapter J-36667 and the lock plate compressor J-23653-D.





18. Place the retaining ring into the groove on the upper shaft.





19. Connect the turn signal switch housing to the steering column housing with the turn signal switch housing screws.
Tighten the turn signal switch housing screws to 3 Nm (27 inch lbs.).





20. Slide the alignment bushing over the lower end of the steering shaft and into the lower end of the jacket assembly.
21. Install the steering column into the vehicle.

Important: After the steering column is connected to the coupling flange, pull the alignment bushing away from the jacket assembly and leave the bushing on the steering shaft for later use.

22. Install the canceling cam spring and the steering wheel onto the steering column.
