HUB / BEARING (Continued)
DIAGNOSIS AND TESTING - HUB AND
BEARING (REAR)
With the wheel, disc brake caliper, and brake rotor
removed, rotate the wheel hub. Any roughness or
resistance to rotation may indicate dirt intrusion or a
failed wheel bearing. If the bearing exhibits any of
these conditions during diagnosis, replace the hub
and bearing. The bearing is not serviceable.
Damaged bearing seals and the resulting excessive
grease loss may also require hub and bearing
replacement. Moderate grease seepage from the bear-
ing is considered normal and should not require
replacement of the hub and bearing.
To diagnose a bent hub, (Refer to 5 - BRAKES/HY-
DRAULIC/MECHANICAL/ROTORS - DIAGNOSIS
AND TESTING).
