Removal and Installation
CAUTION:
^ Before removing the rear axle, disconnect the ABS wheel sensor from the assembly. Then move it away from the axle. Failure to do so may result in damage to the sensor wires and the sensor becoming inoperative.
^ Wheel bearing does not require maintenance.
^ If growling noise is emitted from wheel bearing during operation, replace wheel bearing assembly.
^ If the wheel bearing assembly is removed, it must be replaced. The old assembly must not be reused.
REMOVAL
