REMOVAL





- Remove brake caliper assembly and rotor.

CAUTION:
- Brake hose need not be disconnected from brake caliper. Be careful not to depress brake pedal, or piston will pop out. Do not pull or twist brake hose.
- Before removing the front axle assembly, disconnect the ABS wheel sensor from the assembly. Then, move it away from the front axle assembly area. Failure to do so may result in damaging the sensor wires and the sensor will become inoperative.

INSPECTION
Wheel bearing
Check wheel bearing to see that it rolls freely and is free from noise, cracks, pitting, or wear, and replace if damaged.

Wheel hub
Check wheel hub for crack by a magnetic exploration or dyeing test, and replace if cracked.

Knuckle spindle
Check knuckle spindle for deformation, tapping mark, or cracks (by magnetic or dyeing test) and replace if damaged.

INSTALLATION





- Press new wheel bearing assembly into wheel hub.
Maximum load P: 29 kN (3 ton, 3.3 US ton, 3.0 Imp. ton)

CAUTION:
- Do not press inner race of wheel bearing assembly.
- Do not apply oil or grease to mating surfaces of wheel bearing outer race and wheel hub.
