Part 1 Of 2:




Part 2 Of 2:






^ Tools Required:
- J 21854-01 Pivot Pin Remover
- J 41688 Centering Sphere Installer Tool

REMOVE OR DISCONNECT

NOTICE: Once steering column is removed from vehicle, the column is extremely susceptible to damage. Dropping steering column assembly on its end could collapse steering shaft or loosen plastic injections which maintain column rigidity. Leaning on steering column assembly could cause jacket to bend or deform. Any of the above damage could impair steering column's collapsible design. If it is necessary to remove steering wheel, use only the specified steering wheel puller. Under no conditions should the end of shaft be hammered on as hammering could loosen plastic injections which maintain steering column rigidity.

1. Negative (-) battery cable.
2. Disable the SIR System; refer to DISABLING THE SIR SYSTEM.
3. Steering column assembly from vehicle.
4. Three tapping screws (26) from upper cover (17).
5. Upper cover (17).
6. Wire restraint clip (56) from bottom of steering column jacket support assembly (54).
7. All wire harnesses from wire harness strap (57).
8. Two tapping screws (26) from pivot & pulse switch assembly (16).
9. Pivot & pulse switch (16).
^ Let switch (16) hang freely.
10. Two tapping screws (26) from turn signal & multifunction switch (32).
11. Turn signal & multifunction switch (32).
^ Pass key wire from securing location on multifunction switch (32).
^ Let switch (32) hang freely.
12. Do all steps under REMOVE OR DISCONNECT in WHEEL TILT SPRING.
13. Lower spring retainer (64).
14. Lower bearing spring (63).
15. Lower bearing seat (62).
16. Adapter & bearing assembly (61) from jacket assembly (60).





17. Two pivot pins (53) using J 21854-01.





18. Bearing & housing assembly (11) with steering shaft assembly.
^ Pull tilt arm to disengage steering wheel lock shoes from dowel pins in steering column jacket support assembly (54).

Inspect





^ Steering shaft assembly for accident damage.








Important: Mark upper shaft assembly (35) and lower steering shaft assembly (38) to ensure proper assembly. Failure to assemble properly will cause steering wheel to be turned 180°.

DISASSEMBLE
^ Lower steering shaft assembly (38) from upper shaft assembly (35) and housing assembly (11).
A. Upper shaft assembly (35) from lower shaft assembly (38).
^ Tilt 90° to each other and disengage.
B. Centering sphere (36) from upper shaft assembly (35).
^ Rotate sphere 90° and slip out.
C. Joint preload spring (37) from centering sphere (36).

INSTALL OR CONNECT

NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems. Failure to do so may result in component damage or malfunction of steering column.

1. If necessary, remove and discard the old centering sphere and spring.





2. Grease the sphere with lithium grease. Grease the lower half of the sphere in the upper shaft assembly engagement areas. Grease the upper half of the sphere in the shaft engagement areas opposite to the greased areas of the lower half of the sphere.
3. Place the base of the tool in a vise. Then place (in order shown) the bottom half of the new centering sphere, the new spring, the top half of the new centering sphere, and the driver in the Centering Sphere Installer tool #J4168.





4. Compress the spring and rotate the driver 90° in the clockwise direction.





^ Make sure that the feet of the driver slide into grooves in the base. Rotate driver until arms lock in place.





5. Once sphere is locked in place, attach the upper shaft assembly.
^ After the upper shaft assembly is firmly attached to the centering sphere, rotate the shaft 90° downward locking the centering sphere in place.





6. Remove the centering sphere installer and the upper shaft assembly from the vise. Disassemble the tool by separating the base. After the tool is disassembled, the shaft with the attached sphere can be removed.





7. Apply lithium grease to the exposed shaft engagement area and then install the lower shaft assembly.

ASSEMBLE
^ Lower steering shaft assembly (38) to upper shaft assembly (35) and housing assembly (11).
A. Joint preload spring (37) to centering sphere (36).
B. Centering sphere (36).
^ Lubricate with lithium grease. Slip into upper shaft assembly (35) and rotate sphere 90°.
C. Lower steering shaft assembly (38) to upper shaft assembly (35).
^ Line up marks and tilt assemblies 90° to each other.

19. Four support screws (50).
20. Steering column jacket support assembly (54).
