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".
