    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.

  15. Remove the steering column assembly.
  16. Rotate the column so that the shift lever clears the dash panel (2) opening.

Installation Procedure

    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.

    Caution: If steering column to cowl panel seal is torn or otherwise damaged, it must be replaced. Confirm that the seal and inner race are properly located. Failure to do so may allow carbon monoxide into the vehicle, which may result in serious personal injury or death.

  1. Lower the end of the steering column through the dash panel (2) opening and the steering column seal (1).
  2. Connect the harness to the connectors on the steering column.

  3. Object Number: 245841  Size: SH
  4. Raise the steering column into place.
  5. Rotate the column up over the two upper studs.
  6. Loosely assembly the two nuts.

  7. Install the lower column nuts.
  8. 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.

  9. Install the upper column nuts.
  10. Tighten
    Tighten the lower and upper column nuts to 30 N·m (22 lb ft).


    Object Number: 590179  Size: SH
  11. Install the bolt and the nut to the upper end of the shaft.
  12. Tighten
