    Important:  The wheel speed sensor mounts to the hub/bearing assembly. Thoroughly clean around this area in order to prevent any dirt or contaminants from entering the sealed wheel bearing. Failure to do this may lead to premature wheel bearing failure.

  4. Remove the wheel speed sensor (WSS) mounting bolt.
    NOTE: Carefully remove the sensor by pulling it straight out of the bore. DO NOT use a screwdriver, or other device to pry the sensor out of the bore. Prying will cause the sensor body to break off in the bore.
  5. Remove the wheel speed sensor (5) from the hub/bearing assembly (4).
  6. Remove the WSS cable mounting clip from the knuckle.
  7. Remove the WSS cable mounting clip from the upper control arm.
  8. Remove the WSS cable mounting clip from the frame attachment point.
  9. Remove the WSS cable electrical connector.
