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.

Install the J 42640 in the steering column lower access hole.

IMPORTANT: Mark the relationship of the intermediate shaft components in order to assure proper installation.

Mark the relationships of the following components:
- Mark the relationship of the bolt and clamp at both ends of the upper intermediate shaft.
