4. Remove the antilock brake system (ABS) speed sensor wiring harness from the upper control arm.





5. Remove the front retaining bolt for the speed sensor bracket at the upper control arm.





6. Remove the speed sensor bracket from the upper control arm.





Important: Mark the holes used to mount the speed sensor electrical connector before removing. This will ensure the proper location of the speed sensor electrical connector for installation.

7. Remove the speed sensor electrical connector from the body.





Important: The following service procedure is to ensure that the speed sensor wiring harness is properly positioned so that the length of the wiring harness is correct for installation. Failure to do so could cause damage to the speed sensor wiring harness.

8. Using white or bright colored paint, mark the location of the speed sensor wiring harness to the steering knuckle.





Important: The splash shield will come off the steering knuckle when the wheel bearing/hub, brake rotor is removed.

9. Remove the mounting bolts for the wheel bearing/hub, brake rotor assembly.





10. Remove the wheel bearing/hub assembly from the knuckle.





Important: Perform the following service procedure with the brake rotor on a flat surface.

11. Remove the mounting bolt from the wheel bearing/hub, to the brake rotor.





12. Remove the wheel bearing/hub from the brake rotor.
13. Clean the contact area between the wheel bearing/hub and the brake rotor.

Installation Procedure

1. If Necessary, install a new wheel speed sensor on the bearing hub.





2. Position the wheel bearing/hub assembly on the brake rotor.
3. Install the mounting bolts from the wheel bearing/hub assembly to the brake rotor.

Notice: Refer to Fastener Notice in Service Precautions.

Important: The following service procedure is to be performed on a flat surface and to ensure that the brake rotor is securely attached to the hub assembly prior to the final torquing procedure. DO NOT use air tools of any type for this procedure.
