NOTE
Be careful not to damage the sensor edge and sensor rotor teeth. When removing the hub assembly, first remove the ABS wheel sensor from the assembly. Failure to do so may result in damage to the sensor wires making the sensor inoperative.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Raise and support the vehicle safely.
  6.  
  7. Remove the tire and wheel assembly, as necessary.
  8.  
  9. Remove the wheel speed sensor mounting bolts, grommets and clip.
  10.  
  11. Pull the sensor out, being careful to turn it as little as possible. Do not pull on the sensor harness.
  12.  

To install:

  1. Before installing the sensor be sure no foreign materials such as iron fragments are adhered to the pick-up part of the sensor or to the inside of the sensor mounting hole or on the rotor mounting surface.
  2.  
  3. Tighten the sensor retaining bolt to specification.
  4.  
  5. Be sure the harness is not twisted when installed.
  6.  
  7. Continue the installation in the reverse order of the removal procedure.
