Removal Procedure

    NOTE: 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.
    NOTE: Do not support the steering column by only the lower or upper support bracket. Damage to the column lower bearing adapter could result.
    IMPORTANT: In the event of a deployment, inspect the coil wire for any of the following signs of damage due to excessive heat:
    • Scorching
    • Melting
    • Other damage

    Replace the coil, if necessary.
    NOTE: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly to become uncentered, which may cause damage to the coil assembly.
