Front Hub Unit Bearing
REMOVAL
1. Disconnect the ground cable from battery.
2. Lift-up the vehicle and remove the front wheels.
3. Unlock the axle nut.
4. Remove the axle nut using a socket wrench while depressing the brake pedal.
CAUTION: Remove the wheel before loosening the axle nut. Failure to follow this rule may damage the wheel bearings.
5. Remove the disc brake caliper from housing, and suspend it from strut using a wire.
6. Remove the disc rotor from hub.
NOTE: If the disc rotor seizes up within hub, drive disc rotor out by installing an 8-mm bolt in screw hole on rotor.
7. Remove four bolts from housing.
CAUTION:
^ Do not get closer the tool which charged magnetism to magnetic encoder.
^ Be careful not to damage the magnetic encoder.
8. Remove the front hub unit bearing. If it is hard to remove, use STs.

ST 28399AG000 HUB STAND
CAUTION:
^ Be careful not to hammer the hub bolts. This may deform the hub.
^ Do not reuse the hub bolt.
NOTE: Since the hub unit bearing can not be disassembled, only hub bolts can be removed.
ASSEMBLY
1. Attach the hub to ST securely.
ST 927080000 HUB II STAND
2. Using a press, press new hub bolts until their seating surfaces contact the hub.
NOTE: Use 12 mm (0.47 inch)dia. holes in HUB STAND to prevent bolts from tilting.
INSPECTION
Refer to FRONT AXLE for inspection procedures.
CAUTION: If there is any fault in the bearing, replace hub unit bearing.
