damage) are normal.

WHEEL BEARING INSPECTION

• Move wheel hub in the axial direction by hand. Make sure there is

no looseness of wheel bearing.

• Rotate wheel hub and make sure there is no unusual noise or

other irregular conditions. If there are any irregular conditions,

replace wheel hub and bearing assembly.
