Welcome to 2CarPros.

Here are the directions for replacing the rack. Any specialized tooling (SST) is indicated in the directions. Other than the SST, the standards will be needed, sockets, wrenches, screw drivers and so on. All of the attached pictures correlate with the directions.

1. Lock the steering column by installing J42640 into the underside of the steering column.
2. Raise and support the vehicle. Refer to Vehicle Lifting.
3. Remove the tires and wheels.
4. Remove the power steering gear heatshield.

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

Notice: 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 coil assembly in the steering column to become uncentered which will cause damage to the coil assembly.
