Make sure that the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are normal.

WHEEL BEARING INSPECTION

●

Move wheel hub and bearing assembly in the axial direction by hand. Make sure there is no looseness of
wheel bearing.

Temporarily tighten the nut to prevent damage to threads and to prevent ball joint remover (suit-
able tool) from suddenly coming off.

6.

Remove fixing nut and bolt with power tool, and then remove steering knuckle from upper link. Refer to

FSU-8, "Components"

 .

7.

Remove wheel hub and bearing assembly mounting bolts, and then remove splash guard and wheel hub
and bearing assembly from steering knuckle.

INSPECTION AFTER REMOVAL

Check components for deformation, cracks, and other damage. Replace if there are.

Ball Joint Inspection

Check boots of transverse link and steering outer socket ball joint for breakage, axial play, and torque. Refer to
