J 42640 Steering Column Anti-Rotation Pin

Removal Procedure


    Object Number: 333146  Size: SH

    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.

  1. Install the J 42640 in the steering column lower access hole.
  2. Important: Mark the relationship of the intermediate shaft components in order to assure proper installation.

  3. Mark the relationships of the following components:
  4. • Mark the relationship of the bolt and clamp at both ends of the upper intermediate shaft.
    • Mark the relationship of the upper intermediate shaft to the lower intermediate shaft.

  5. Remove the nut and bolt from the lower shaft to upper shaft connection.

  6. Object Number: 748880  Size: SH
  7. Remove the nut and bolt (1) from the upper shaft to steering column connection.
  8. Slide the intermediate shaft down, out of the steering column connection.
  9. Remove the accelerator pedal position sensor. Refer to Accelerator Pedal Position Sensor Replacement or Accelerator Pedal Position Sensor Replacement or Accelerator Pedal Position Sensor Replacement in Engine Controls.
  10. Slide the upper intermediate shaft towards the instrument panel, out of the lower intermediate shaft, and remove the shaft from the vehicle.

Installation Procedure


    Object Number: 748880  Size: SH

    Important: If you are installing the same shaft, align the marks and the relationship of the bolt and clamp made during the removal procedure.

  1. Install the lower end of the upper intermediate shaft through the bulkhead, into the lower shaft.
  2. Install the upper end of the upper intermediate shaft to the steering column.
  3. 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.

  4. Install the bolt and nut (1) at the connection of the upper intermediate shaft and the steering column.
  5. Tighten
    Tighten the nut to 62 N·m (46 lb ft).

  6. Install the accelerator pedal position sensor. Refer to Accelerator Pedal Position Sensor Replacement or Accelerator Pedal Position Sensor Replacement or Accelerator Pedal Position Sensor Replacement in Engine Controls.

  7. Object Number: 362505  Size: SH
  8. Install the bolt and nut at the connection of the upper intermediate shaft and the lower intermediate shaft.
  9. Tighten
    Tighten the nut to 47 N·m (35 lb ft).
