REMOVALNOTE: Before proceeding with this procedure, Refer to Service Precautions.
1. Raise the vehicle.
2. Disconnect the Wheel Speed Sensor (WSS) cable connector from the wiring harness on the inside of the frame rail above the front suspension crossmember. The connector has a locking tab which that must be pulled back before the connector release tang can be depressed, releasing the connection.
3. Remove the speed sensor cable grommet from the retaining bracket attached to the brake hose on the outside of the frame rail.
4. Remove the bolt mounting the WSS head to the steering knuckle.
CAUTION: When removing a wheel speed sensor from the knuckle, do not use pliers on the sensor head. This may damage the sensor head. If the sensor has seized, use a hammer and a punch to tap the edge of the sensor head ear, rocking the sensor side-to-side until free.
5. Carefully, remove the sensor head from the steering knuckle.
6. Remove the screw securing the WSS to the rear of the strut. Remove the WSS.
INSTALLATION
NOTE: Before proceeding with this procedure, Refer to Service Precautions.
CAUTION: Failure to install speed sensor cables properly may result in contact with moving parts or an over extension of cables causing an open circuit. Be sure that cables are installed, routed, and clipped properly.
1. Attach the Wheel Speed Sensor (WSS) to the strut using the its mounting screw.
2. Install the WSS head in the steering knuckle. Install the mounting bolt. Tighten the mounting bolt to a torque of 12 Nm (105 inch lbs.).
3. From the sensor bracket on the strut, loop the sensor cable upward, then downward at the outside of the frame rail. Install the speed sensor cable grommet onto the retaining bracket attached to the brake hose on the outside of the frame rail.
4. Loop the WSS cable around the bottom of the frame rail and connect it to the wiring harness connector on the inside of the frame rail. Remember to push in the locking tab on the connector.
5. Lower the vehicle.
6. Road test vehicle to ensure proper operation of the base brakes and Antilock Brake System (ABS).
