Removal and Installation

CAUTION: If equipped with ABS, disconnect the ABS wheel sensor from the assembly before removing the front axle assembly. Then move it away from the front axle assembly area. Failure to do so may result in damage to the sensor wires and the sensor becoming inoperative.





1. Remove free-running hub assembly (4WD models).
2. Remove brake caliper assembly without disconnecting hydraulic line.

CAUTION:
