J 42640 Steering Column Lock Pin

Removal Procedure

  1. Turn the steering wheel far enough to the left to gain access to the upper to lower intermediate shaft bolts.
  2. Caution: 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.
