Removal Procedure

  1. Raise the vehicle.
  2. Remove the tire and wheel.
  3. Remove the brake caliper. Refer to FRONT BRAKE CALIPER .
  4. Remove the hub and rotor (5). Refer to FRONT BRAKE ROTOR .
  5. Remove the wheel speed sensor mounting clips on the control arm and frame.
  6. Remove the wheel speed sensor electrical connector.
    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.

    Important:  The wheel speed sensor mounts into a bore that leads to the center of the sealed bearing. Use caution when cleaning or working around the bore. Do not contaminate the lubricant inside the sealed bearing. Failure to do so can lead to premature bearing failure.

  7. Remove the wheel speed sensor from hub and bearing assembly (4). I
