    Caution: When servicing the steering column, the Supplemental Inflatable Restraint (SIR) System clock spring must be centered for proper steering wheel operation. Failure to properly center the SIR clock spring may result in reduced turnability of the steering wheel causing the vehicle to improperly maneuver and may cause the SIR system to be inoperative.

    Notice: Do not rotate the steering wheel or move the position of the steering gear once the intermediate shaft is disconnected. This will uncenter the Inflatable Restraint coil in the steering column. If the Inflatable Restraint coil becomes uncentered, it may be damaged during vehicle operation.

  1. Turn the front wheels straight ahead.

  2. Object Number: 1223218  Size: SH

    Important: The coil spring may come packed in material used to prevent damage to the spring during shipping or storage. Avoid installing any of the packing material with the coil spring.

  3. Turn the label of the coil spring clockwise to lock.
  4. Turn the label of the coil spring counterclockwise approximately 3 turns to the neutral positions with the front wheels ahead.
  5. Properly align the pointed marks on the components of the coil spring.
