Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Raise and safely support the vehicle.
  4.  
  5. Disconnect the wheel speed sensor 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.

  9. Remove the speed sensor cable grommet from the retaining bracket attached to the brake hose on the outside of the frame rail.
  10.  
  11. Remove the bolt mounting the wheel speed sensor head to the steering knuckle.
    WARNING
    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.

To install:


WARNING
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 to the strut using the its mounting screw.

  5. 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.
  6.  
  7. Loop the wheel speed sensor 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.

  6.  
  7. Remove the wheel speed sensor cable routing bracket from under rear brake flex hose mounting bracket. Then remove the speed sensor cable from the routing clips on the rear brake flex hose and chassis brake tube.
  8.  
  9. Remove the bolt attaching the wheel speed sensor cable routing bracket to rear strut.
    WARNING
    When removing a wheel speed sensor from the rear disc brake adapter, 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.

  10.  
  11. Remove the bolt attaching the wheel speed sensor to the rear disc brake adapter, then carefully remove the sensor head from the rear disc brake adapter and vehicle.
