Removal Procedure

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

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

  1. Disable the SIR system. Refer to Disabling the SIR System in SIR.
  2. Notice: The vehicle's wheels must be in a straight-ahead position and the key must be in a LOCK position when removing or installing the steering column. Failure to do so may cause the SIR coil assembly to become uncentered and may result in unneeded SIR system repairs.

  3. Remove the trim covers. Refer to Steering Column Trim Covers Replacement - On Vehicle .
  4. Disconnect all of the electrical connectors.
  5. Remove the electrical harness from the steering column.
  6. Remove the intermediate shaft upper pinch bolt from the steering column. Refer to Intermediate Steering Shaft Seal Replacement .

  7. Object Number: 307353  Size: SH
  8. Loosen the lower steering column mounting bolts.
  9. Remove the upper steering column mounting bolts.
  10. 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.

  11. Remove the steering column from the vehicle.

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.

  1. Install the steering column to the vehicle.
  2. Install the steering column shaft to the intermediate shaft. Refer to Intermediate Steering Shaft Seal Replacement .
  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 intermediate shaft upper pinch bolt.
  5. Tighten
    Tighten the intermediate shaft upper pinch bolt 40 N·m (30 lb ft).


    Object Number: 307353  Size: SH
  6. Tighten the lower steering column mounting bolts.
  7. Tighten
    Tighten the lower steering column mounting bolts to 27 N·m (20 lb ft).

  8. Install the upper steering column mounting bolts.
  9. Tighten
    Tighten the upper steering column mounting bolts to 27 N·m (20 lb ft).

  10. Connect all of the electrical connectors.
  11. Install the electrical harness to the steering column.
  12. Install the trim covers. Refer to Steering Column Trim Covers Replacement - On Vehicle .
  13. Enable the SIR. Refer to Disabling the SIR System in SIR.
