    Warning: 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.

    Caution: 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. Turn the lobe of the clock spring clockwise to lock. Do not force.
  3. Turn the lobe of the clock spring counterclockwise approximately 2.5 turns to the neutral position, with the front of the wheels straight ahead.
  4. Properly align the pointed marks on the components of the clock spring.
