The following procedure may be used for diagnosing
the condition of the front hub bearing.
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 hub bearing. If the hub bearing exhibits any of
these conditions during diagnosis, the hub and bear-
ing will require replacement. The bearing is not ser-
viceable.
Damaged bearing seals and the resulting excessive
grease loss may also require bearing replacement.
Moderate grease weapage from the hub bearing is
considered normal and should not require replace-
ment of the hub and bearing.
To check for excessive hub runout, refer to BRAKE
ROTOR in the DIAGNOSIS AND TESTING section
of service manual group BRAKES for the procedure.
LOWER CONTROL ARM
The lower control arm if damaged, is serviced only
as a complete component. Do not attempt to repair
or straighten a broken or bent lower control
arm. Inspect the lower control arm for signs of dam-
age from contact with the ground or road debris. If
the lower control arm shows any sign of damage,
inspect the lower control arm to see if it is bent.
The only serviceable components of the lower con-
trol arm are, the pivot bushing, and the tension strut
bushing. The service procedure to replace these com-
ponents is detailed in the specific component Service
Procedures Sections in this group of the service man-
ual.
BALL JOINT
Raise front of vehicle using jack stands or a frame
contact type hoist, until front suspension is in full
rebound and tires are not in contact with the ground.
Grasp tire at top and bottom, and apply an in and
out on the wheel and tire. While applying force to the
tire, look for any movement between the lower ball
joint and lower control arm. If any movement is evi-
dent the lower ball joint is worn and the lower con-
trol arm requires replacement.
STABILIZER BAR (FRONT)
Inspect for broken or distorted retainers and bush-
ings. If bushing replacement is required, bushing can
be removed by opening slit in bushing and removing
bushing from around stabilizer bar. The stabilizer
bar to cradle assembly bushings, should be positioned
on stabilizer bar, so slit in bushing is positioned
