Front Wheel Hub Bearing

On-Vehicle Inspection

1. Checking noise from front wheel hub bearing
(a) Perform road test on a flat road surface, and make sharp left or right turns during straight
driving to check if front wheel hub bearing produces noise.
Tips:
• If your vehicle produces noise during right turn, it indicates that you may need to replace
left front wheel hub bearing with a new one. Then, check left front wheel hub bearing
clearance.
• If your vehicle produces noise during left turn, it indicates that you may need to replace
right front wheel hub bearing with a new one. Then, check right front wheel hub bearing
clearance.
• If your vehicle produces noise during both left turn and right turn, check the side with
heavier noise in the same way above.

looseness.

to check that it should rotate smoothly
without noise.
