J-42640 - Steering Column Anti-rotation Pin

Removal Procedure





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 became un-centered, refer to your specific SIR coil's centering procedure to re-center SIR Coil.

1. Insert J-42640 - pin into the steering column access hole in order to lock the steering column.
2. Raise and support the vehicle. Refer to Vehicle Lifting (Service and Repair).
3. Place a drain pan under the vehicle.




4. Remove the tire and wheel assemblies. Refer to Tire and Wheel Removal and Installation (Service and Repair).





Warning

Failure to disconnect the intermediate shaft from the rack and pinion steering gear stub shaft can result in damage to the steering gear and/or intermediate shaft. This damage may cause loss of steering control which could result in an accident and possible personal injury.
