Caution: The steering column must be in the LOCK position before disconnecting the following components:

   • The steering column
   • The steering shaft coupling
   • The intermediate shaft
   • The lower steering shaft
After disconnecting these components, do not move the front tires and wheels. Failure to follow these procedures may cause improper alignment of some components during installation and result in possible damage to the SIR coil.

Caution: Once the steering column is removed from the car, the column is extremely susceptible to damage. Dropping the column on its end could collapse the steering shaft or loosen the plastic injections which maintain column rigidity. Leaning on the column could cause the jacket to bend or deform. Any of the above damage could impair the column's collapsible design. If it is necessary to remove the steering wheel, use only the specified steering wheel puller. Under no conditions should the end of the shaft be hammered upon as hammering could loosen plastic injections which maintain column rigidity.

Removal Procedure

  1. Remove the instrument panel lower trim pad cover. Refer to Instrument Panel Lower Trim Pad Cover Replacement.
  2. Remove the intermediate steering shaft. Refer to Intermediate Steering Shaft Replacement.
  3. Remove the steering wheel. Refer to Steering Wheel Replacement.
  4. Remove the steering column upper trim cover. Refer to Steering Column Upper Trim Cover Replacement.
  5. Remove the steering column lower trim cover. Refer to Steering Column Lower Trim Cover Replacement.
  6. Disconnect electrical connectors as needed.
  7. Note: Install tie straps between the tilt lever bracket and the base of the steering column to prevent the steering column jacket from pulling apart. The tilt lever MUST be in the LOCK (FULL UP) position during the steering column removal and installation to ensure that the tilt lever bracket remains rigid. Also install tie straps around the tilt lever and the steering column jacket to keep the tilt lever in the LOCK position. Do not bend the steering column energy absorbing straps located on the upper steering column mounting bracket.

  8. Install tie straps as described above.

  4. Warning: 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.
