J 42640 Steering Column Anti-Rotation Pin

Removal Procedure

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 SIR coil assembly to become uncentered, which may cause damage to the coil assembly.

Important: If the inflatable restraint module is deployed, inspect the SIR coil.

Replace the SIR coil if the SIR coil exhibits any signs of damage caused by excessive heat.

  1. Disable the SIR system. Refer to Disabling the SIR System in SIR.

  2. Object Number: 333146  Size: SH
  3. Install the J 42640 to the steering column.
  4. Remove the steering wheel. Refer to Steering Wheel Replacement .
  5. Remove the knee bolster trim panel. Refer to Knee Bolster Replacement in Interior Trim.
  6. Push the top of the intermediate shaft seal down in order to access to the intermediate shaft upper retaining bolt.
  7. Remove the steering column intermediate shaft upper retaining bolt and nut.
  8. Disconnect the steering column electrical connectors.
  9. Column Shift Only. Disconnect the shift cable from the control assembly and from the steering column.
  10. Remove the steering column upper mounting nuts.
  11. Remove the steering column lower mounting bolts.
  12. Remove the steering column anchor cable from the bracket.
  13. Remove the steering column from the vehicle.

Installation Procedure


    Object Number: 305570  Size: SH
  1. Install the steering column to the vehicle.
  2. Install the steering column to the intermediate shaft.
  3. Install the steering column anchor cable to the bracket stud.
  4. Caution: In order to ensure the intended function of the steering column in a vehicle during a crash and in order to avoid personal injury to the driver, perform the following:

       • Tighten the steering column lower fasteners before you tighten the steering column upper fasteners. Failure to do this can damage the steering column.
       • Tighten the steering column fasteners to the specified torque. Overtightening the upper steering column fasteners could affect the steering column collapse.

  5. Install the steering column nuts.
  6. 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.

  7. Install the steering column bolts.
  8. Tighten the steering column fasteners in the following order.
  9. Tighten

        • Tighten the bolts to 24 N·m (18 lb ft).
        • Tighten the nuts to 24 N·m (18 lb ft).
