1. Disconnect the electrical connector.
2. Remove the nylon straps retaining the sensor wire to the brake line. Note the location of the straps.
3. Remove the wheel speed sensor from the bore.
4. Remove the speed sensor retaining clip. The clip may come out with the wheel speed sensor or stay in the bore.

•	If the sensor retaining clip is still functioning correctly, save the clip for reinstallation.

•	If the sensor retaining clip is not functioning correctly, replace the sensor retaining clip.

5. Inspect the wheel speed sensor tone ring inside the wheel hub/rotor and tone wheel unit.

•	If debris is lodged between the wheel speed senor tone ring teeth, remove any accumulated debris and clean the tone ring.

•	If any wheel speed sensor tone ring teeth are rusty or otherwise damaged, replace the wheel speed sensor tone ring. If the wheel speed sensor tone ring is integral to the wheel hub, both sides should be replaced on the axle.

Important: You may have to use the wire retainers from the old wheel speed sensor wire on the new sensor. Do not damage the new wire when installing the retainers.

Important: When the wheel speed sensor is fully installed in the block bore, it contacts the tone ring which is attached to the wheel hub. Normal bearing play between the sensor tip and tone ring in the wheel hub will move the sensor tip away from the tone ring. This automatically establishes the proper air gap.




1. Install the wheel speed sensor retaining clip (3) completely into the bore. The clip should stop at the retaining tabs. Insert the wheel speed sensor into the clip. The wheel speed sensor should contact the tone ring.
2. Secure the sensor wire (2) to the brake line (4) with a wire tie (1) in the location noted during removal.
3. Connect the electrical connector (5).
