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.

    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.

    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.

  1. Disable SIR system. Refer to Disabling the SIR System in SIR.
  2. Important: In the event deployment has occurred, inspect the turn signal and headlamp and windshield washer switch with levers and inflatable restraint coil assembly for any signs of scorching, melting or other damage due to excessive heat. If the turn signal and headlamp dimmer switch, the windshield wiper and windshield washer switch, or the steering wheel inflatable restraint module coil is damaged, replace the damaged component. If more than one component is damaged, or the base of the assembly is damaged, replace the complete assembly.

    Important: If you are servicing the steering column or any column-mounted component, remove the steering wheel. If you are removing the steering column simply to gain access to the instrument panel components, leave the steering wheel installed on the column.
