J 42640 Steering Column Anti-Rotation Pin

Removal Procedure

Notice: Once the steering column is removed from the vehicle, the column is extremely susceptible to damage. Dropping the column assembly on the end could collapse the steering shaft or loosen the plastic injections, which maintain column rigidity. Leaning on the column assembly could cause the jacket to bend or deform. Any of the above damage could impair the columns collapsible design. Do NOT hammer on the end of the shaft, because hammering could loosen the plastic injections, which maintain column rigidity. If you need to remove the steering wheel, refer to the Steering Wheel Replacement procedure in this section.

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.

    Caution: This vehicle is equipped with a Supplemental Restraint System (SRS). Failure to follow the correct procedure could cause the following conditions:

       • Air bag deployment
       • Personal injury
       • Unnecessary SRS system repairs
    In order to avoid the above conditions, observe the following guidelines:
       • Refer to SRS Component Views in order to determine if you are performing service on or near the SRS components or the SRS wiring.
       • If you are performing service on or near the SRS components or the SRS wiring, disable the SRS system. Refer to Disabling the SRS System in SRS.

  1. Disable the SRS system. Refer to Disabling the SRS in SRS.
  2. Remove the knee bolster. Refer to Knee Bolster Replacement in Instrument Panel, Gauges and Console.
  3. Remove the shift cable from the steering column (column shift only). Refer to Shift Cable Replacement in Automatic Transmission - 4L60-E.

  5. Lock the steering column through the access hole in the lower steering column trim cover using J 42640 .

  6. Object Number: 401496  Size: SH
  7. Loosen the center screw in order to remove the steering column bulkhead connector.

  8. Object Number: 395780  Size: SH
  9. Remove the nuts that retain the steering column to the steering column toe plate.
  10. Remove the nuts that retain the steering column to the steering column upper support bracket.
  11. Remove the steering column from the vehicle.
  12. Remove the upper intermediate shaft from the steering column.

Installation Procedure


    Object Number: 395780  Size: SH
  1. Install the upper intermediate shaft to the steering column.
  2. Install the steering column to the vehicle.
  3. 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.

  4. Install the nuts that retain the steering column to the steering column toe plate.
  5. 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.

  6. Install the nuts that retain the steering column to the steering column upper support bracket.
  7. Tighten

    1. Tighten the steering column to the steering column toe plate retaining nuts to 30 N·m (22 lb ft).
    2. Tighten the steering column to the steering column upper support bracket retaining nuts to 30 N·m (22 lb ft).

    Object Number: 401496  Size: SH
  8. Install the steering column bulkhead connector to the vehicle wire harness.
  9. Tighten
    Tighten the steering column bulkhead connector center screw to 6 N·m (53 lb in).
