Tools Required

J 42640 Steering Column Anti-Rotation Pin

Notice: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the coil assembly in the steering column to become uncentered which will cause damage to the coil assembly.

  1. Mark the relationships of the intermediate shaft to the following components in order to ensure proper installation:
  2. • The steering column shaft
    • The steering gear input shaft
  3. Disable the SIR system. Refer to Disabling the SIR System in SIR.

Installation Procedure


    Object Number: 361689  Size: SH
  1. Align the flat on the intermediate shaft with the flat on the steering gear shaft.
  2. Observe the marks that were made before the disassembly.

    Install the intermediate shaft to the steering gear shaft.

    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.

  3. Install the intermediate shaft pinch bolt.
  4. Tighten
    Tighten the intermediate shaft pinch bolt to 41 N·m (30 lb ft).
