- Or Equivalents
NOTE: Before doing any service procedures, disabling the Supplemental Inflatable Restraint (SIR) system and removal of Inflator Module and Steering Wheel is needed. (Refer to "Disabling the SIR System" and also service procedures in "Steering Wheel And Column On-Vehicle Service.")
REMOVE OR DISCONNECT
1. Disable the SIR system.
2. Negative (-) battery cable.
3. Steering column from vehicle. "Steering Wheel And Column On-Vehicle Service"
CAUTION: 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.
^ 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 16 under "REMOVE OR DISCONNECT", refer to Sub Section B.
6. Pivot pins (39) using J 21854-01.
^ Reinstall tilt lever. Refer to "Steering Wheel And Column On-Vehicle Service"

INSTALL OR CONNECT
CAUTION: Always use the correct fastener in the correct 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 the 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.
CAUTION: Ensure all fasteners are securely seated before applying needed torque. Failure to do so may result in component damage or malfunctioning of steering column.
