Removal Procedure

Tools Required

J 42640 Steering Column Anti-Rotation Pin

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 front wheels of the vehicle must be maintained in the straight ahead position and the steering column must be in the LOCK position before disconnecting the steering column or intermediate shaft. Failure to follow these procedures will cause improper alignment of some components during installation and result in damage to the SIR coil assembly.

    Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

  1. Disconnect the battery negative cable.
  2. Disable the SIR system. Refer to Disabling the SIR System in SIR.

Installation Procedure


    Object Number: 284414  Size: MH
  1. Install the steering column through the cowl opening and onto the 2 lower studs.
  2. Raise the steering column into place.
  3. Loosely install the upper column mounting nuts. Do not tighten the nuts.
  4. Connect the auto trans shift lock control connector.
  5. 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.

    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 lower column mounting nuts .
  7. Tighten

        • Tighten the lower column mounting nuts to 30 N·m (22 lb ft).
        • Tighten the upper column mounting nuts to 30 N·m (22 lb ft).
  8. Install the intermediate shaft to the steering column shaft. Refer to Intermediate Steering Shaft Replacement .
  9. Install the transmission control linkage to the column shift lever. Refer to Shift Cable Replacement in Automatic Transmission.
  10. Install the steering wheel. Refer to Steering Wheel Replacement .

  11. Object Number: 284413  Size: SH
  12. Connect the 48-way steering column wire harness to the instrument panel wire harness.
  13. Tighten
    Tighten the wire harness connector bolt to 6 N·m (53 lb in).

  14. Install the driver's knee bolster deflector. Refer to Knee Bolster Deflector Replacement - Left Side in Instrument Panel, Gauges and Console.
  15. Install the driver's knee bolster. Refer to Driver Knee Bolster Replacement in Instrument Panel, Gauges and Console.
