Removal

1. If installing a new steering gear, connect the scan tool and upload the module configuration information from the Power Steering Control Module (PSCM). For additional information, refer to Information Bus.

2. NOTE: Use a steering wheel holding device (such as Hunter(R) 28-75-1 or equivalent).
Using a suitable holding device, hold the steering wheel in the straight-ahead position.






3. Remove the wheels and tires.
