    Object Number: 425442 Size: SH

    Important: Replace the steering column support assembly if the steering column support assembly has been staked 3 times.

  1. Install the steering column support assembly (1) to the telebearing and jacket assembly.

    2. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. 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.

  2. Install the 4 TORX® screws (2).

    3. Tighten
    Tighten the screws to 17 N·m (13 lb ft).
