^ Tools Required:
- J 23653-SIR Lock Plate Compressor
- J 39246 Tilt Spring Compressor
- J 21854-01 Pivot Pin Remover
- J 22635 Lock Shoe and Release Lever Pin Remover and Installer
- J 8092 Driver Handle
- J 38639 Strg Col Housing Bearing Installer
- Or Equivalents

Important: Before doing any service procedures, disabling the Supplemental Inflatable Restraint (SIR) system and removal of Inflator Module and Steering Wheel is needed.

REMOVE OR DISCONNECT
1. Disable the SIR system.
2. Negative (-) battery cable.
3. Steering column from vehicle.

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 or 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.





^ Inspect steering column for accident damage.
4. Do steps 3 through 22 under "REMOVE OR DISCONNECT," refer to SUB SECTION A.
5. Do steps 2 through 10 under "REMOVE OR DISCONNECT," refer to SUB SECTION B.





6. Pivot pins (39) using J 21854-01.
^ Reinstall tilt lever.
7. Steering column housing assembly (30).
^ Pull back on tilt lever and pull steering column housing assembly (30) down and away from column.

Important: Remove only those components necessary to do repairs.

Steering Shaft Assembly

Important:








^ Mark race upper shaft assembly (56) and lower steering shaft assembly (59) to ensure proper assembly. Failure to assemble properly will cause steering wheel to be turned 180°.
^ Remove only those components necessary to do repairs.

Disassemble
A. Race & upper shaft assembly (56), lower steering shaft assembly (59).
^ Tilt 90° to each other and disengage.
B. Centering sphere (57) from upper shaft assembly (56).
^ Rotate sphere 90° and slip out.
C. Joint preload spring (58) from centering sphere (57).

1. Disassemble the lower steering shaft assembly from the upper shaft assembly.

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





2. Tilt the lower steering shaft assembly 90° to and upper shaft assembly and disengage.
3. If necessary, remove and discard the old centering sphere and spring.





4. 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.
5. 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 #J4168G8.





6. 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.





7. 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.





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





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

INSTALL OR CONNECT

NOTICE: When fasteners are removed, always reinstall them at the same location from which they were removed. If a fastener needs to be replaced, use the correct part number fastener for that application. If the correct part number fastener is not available, a fastener of equal size and strength (or stronger) may be used. Fasteners that are not reused, and those requiring thread locking compound will be called out. The correct torque value must be used when installing fasteners that require it. If the above conditions are not followed, parts or system damage could result.
