    CAUTION:

    The anti-rotation pin must be installed AFTER removing the steering wheel bolt. Removal torque of the steering wheel bolt may exceed the threshold of the steering column rivets and damage the steering column rivets, which will disable the telescoping mechanism. If the steering column rivets are damaged, a new steering colum must be installed.

  3. Install the CH-42640  Steering Column Anti-Rotation Pin (1) in the steering column lower access hole.

    CAUTION:

    With wheels of the vehicle facing straight ahead, secure the steering wheel utilizing steering column anti-rotation pin, steering column lock, or a strap to prevent rotation. Locking of the steering column will prevent damage and a possible malfunction of the SIR system. The steering wheel must be secured in position before disconnecting the following components:

    • The steering column
    • The intermediate shaft(s)
    • The steering gear

    After disconnecting these components, do not rotate the steering wheel or move the front tires and wheels. Failure to follow this procedure may cause the SIR coil assembly to become un-centered and cause possible damage to the SIR coil. If you think the SIR coil has become un-centered, refer to your specific SIR coil's centering procedure to re-center SIR Coil.

    CAUTION:

    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.

  14. Transfer components as necessary.
  15. If replacing the steering column, copy the match marks from the OLD steering column to the NEW steering column.
