CAUTION:

• Remove stud only when necessary.
• Do not hammer the wheel stud or damage to the wheel bearing may occur.
• Pull the wheel stud straight out to avoid damaging the stud.

INSTALLATION

Installation is in the reverse order of the removal.

CAUTION:

• During installation, do not damage the wheel bearing seal. If damage has occurred, replace wheel bearing with a new one.
• Do not allow paint to adhere to the wheel bearing seal.
• Check each mating surface for water and foreign matter. If there is any water or foreign matter, clean the mounting surface.
• Position the stud (1) to the wheel hub flange. Place a washer (A) and nut (B) on the opposite end of the stud, tighten to press the stud into the wheel hub flange.

CAUTION:

• Check that no clearance exists between wheel hub, and wheel stud after installation.
• Do not reuse wheel stud.

• Do not reuse steering knuckle and transverse link nut.
• Clean the mating surface of wheel hub lock nut and wheel hub. CAUTION: Do not apply lubricating oil to the mating surface of the wheel hub lock nut and the wheel hub.
• Clean the mating surface of drive shaft, wheel hub, and wheel bearing. And then apply Molykote M77 to surface (A) of joint subassembly of drive shaft.

  CAUTION: Apply Molykote M77 to cover entire flat surface of joint subassembly of drive shaft.

Molykote M77 quantity : 1.0 - 3.0 g (0.04 - 0.10 oz)

• When reusing disc rotor, align the matching marks during removal.
• Perform the final tightening of each part under unladen conditions, which were removed when removing wheel hub and axle housing.
• When installing a cotter pin, securely bend the basal portion to prevent rattles.

  CAUTION: Do not reuse cotter pin.

Disassembly and Assembly

DISASSEMBLY

1. Remove wheel hub, using Tool.
2. Remove splash guard from steering knuckle

Tool number : ST33710000 ( - )

3. Remove wheel bearing inner race (outer side) from wheel hub, using Tools.
4. Remove snap ring from steering knuckle, using suitable tool.

   CAUTION: Do not damage steering knuckle.

Tool number : ST33710000 ( - )

Tool number : ST30031000 ( - )

    5.   Remove wheel bearing using Tool from steering knuckle.

Tool number : ST35321000 ( - )

ASSEMBLY

1. Install wheel bearing to steering knuckle, using the Tool (A) and a suitable tool (B).

Tool number : ST35271000 ( - )

CAUTION:

• Do not reuse wheel bearing.
• Do not apply a cleaning agent or anticorrosive to the mounting surface of the wheel bearing of steering knuckle.
• Install wheel bearing with the wheel sensor rotor rubber part (C) faced to the steering knuckle inner side.
• The wheel sensor rotor of the wheel bearing must be kept free of foreign matter.
• The press-fit load must be applied to the wheel bearing outer race and the steering knuckle.
• Do not apply press-fit load to the wheel bearing inner race, the seal (C) on the rubber surface side (wheel sensor rotor side), and the seal (D) on the metallic surface side. If a press-fit load is applied, the wheel bearing must be replaced with a new one.
• Wheel bearing press-fit load must be 49 kN (5,000 kg-f, 11,015 lb-f).

    2.   Install snap ring to steering knuckle.

CAUTION:

• Do not damage the wheel bearing seal.
• The snap ring must be installed evenly into the groove.

    3.   Press splash guard (1) into the steering knuckle using suitable tools (A and B).

CAUTION: Do not reuse splash guard.

    4.   Install wheel hub, using Tools.

Tool number (A) : ST33061000 ( - )

Tool number (B) : ST35321000 ( - )

CAUTION:

• Do not apply lubricating oil to the press-fit surface of the wheel hub bearing.
• Set wheel hub and wheel bearing horizontally and insert them vertically.
• The press-fit load must be applied to the wheel hub and the wheel bearing inner race.
• Do not apply press-fit load to the steering knuckle and the wheel bearing, the seal. If a press-fit load is applied, the wheel bearing must be replaced with a new one.

• If the inserted wheel hub is removed again, the wheel bearing must be replaced with a new one.

Inspection

INSPECTION AFTER REMOVAL

Check the following items, and replace the part if necessary.

• Check components for deformation, cracks, and other damage.
• Check boots of transverse link and steering outer socket ball joint for breakage, axial end play, and swing torque. Refer to FSU "Inspection and Adjustment" and ST "Inspection".

INSPECTION AFTER DISASSEMBLY

Wheel Hub

• Check wheel hub for cracks (with magnetic exploration or dye testing). Replace if necessary.

Steering Knuckle

• Check steering knuckle for deformation, cracks, and other damage. Replace if any non-standard conditions are found.

Snap Rings

• Check snap ring for wear or cracks. Replace if necessary.

INSPECTION AFTER ASSEMBLY

Check wheel bearing rotating torque as per the following instructions.

NOTE: The adequacy of turning torque can be judged from a measurement value by a spring balancer.

1. For a proper fit of the bearing, turn the wheel hub both clockwise and counterclockwise, respectively, 10 times or more with a press-fit load of 34,300 - 49,000 N (3,500 - 4,998 kg-f, 7,710 - 11,015 lb-f) applied.
2. Set a spring balance on strut mounting hole (upper). Measure rotating torque at an rpm of 8 - 12 rpm.

Rotating torque : Refer to FAX "Wheel Bearing".

Spring balance measurement : Refer to FAX "Wheel Bearing".

• If the turning torque cannot be obtained by the above method, measure the torque, according to the instructions below.

• Install drive shaft and tighten the hub lock nut to the specified torque. Rotate the wheel hub to fit properly.
• Set a spring balancer to the hub bolt and measure turning torque at turning speeds of 8 to 12 rpm.

Rotating torque : 0.16 N*m (0.016 kg-m, 1.4 in-lb) or less

Spring balance measurement : 0.32 N (0.03 kg-f, 0.07 lb-f) or less

INSPECTION BEFORE INSTALLATION

Check wheel sensor rotor for foreign matter. Clean the rotor, if necessary.

INSPECTION AFTER INSTALLATION

1. Check wheel sensor harness for proper connection. Refer to BRC "FRONT WHEEL SENSOR : Exploded View".
2. Check the wheel alignment. Refer to FSU"Inspection and Adjustment".
