    Object Number: 299877  Size: SH

    Important: Replace the steering column support assembly (1) and the pivot pins if the steering column support assembly (1) and the pivot pins have 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).

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
