Raising and supporting the vehicle enables easy access to change the wss on 4 wheel drive vehicles. You need to detach the brake rotor from 1500 series. Unfasten the wss cable mounting clip from all attachment points and detach the electrical connector followed by unscrewing and removing the wss mounting bolt. Take out the wss in a straight line from its bore using your hands only instead of tools to keep the sensor body intact. To install put the wss bore plug over it until the installation starts. Prepare the wss mounting area on the hub by brushing away debris and apply a thin layer of wheel bearing lubricant gm p/n 01051344 to all surfaces. Place the wss properly into the hub/bearing assembly while maintaining flat contact with the hub surface before applying the wss mounting bolt and tightly tightening it to 18 nm (13 ft. Lbs.). Place the wss cable mounting brackets back onto the common part, upper
Control Arm, and body connection point then join the wss electrical connector. Reinstall the brake rotor into its proper position as depicted in the 1500 series documentation. Reassemble the wheel and tire afterward you run the diagnostic system check for your vehicle.
