STEERING KNUCKLE
The front suspension steering knuckle is not a
repairable component of the front suspension. It
must be replaced if found to be damaged in any way.
If it is determined that the steering knuckle is bent
when servicing the vehicle, no attempt is to be made
to straighten the steering knuckle.
WHEEL BEARING AND HUB
The wheel bearing is designed for the life of the
vehicle and requires no type of periodic maintenance.
The following procedure may be used for diagnosing
the condition of the wheel bearing and hub.
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 bearing exhibits any of
these conditions during diagnosis, the hub bearing
will require replacement. The bearing is not service-
able.Damaged bearing seals and the resulting excessive
grease loss may also require bearing replacement.
Moderate grease weapage from the bearing is consid-
ered normal and should not require replacement of
the wheel bearing.
To diagnose a bent hub, refer to BRAKE ROTOR in
the DIAGNOSIS AND TESTING section in the
BRAKES service manual group for the procedure on
measuring hub runout.
LOWER CONTROL ARM
Inspect the lower control arm for signs of damage
from contact with the ground or road debris. If the
lower control arm shows any sign of damage, look for
distortion. Do not attempt to repair or straighten a
broken or bent lower control arm. If damaged, the
lower control arm stamping is serviced only as a
complete component.
The serviceable components of the lower control
arm are: the ball joint, the ball joint grease seal and
the lower control arm rear isolator bushing.
Inspect both lower control arm isolator bushings
for severe deterioration and replace as required.
Inspect the ball joint per the inspection procedure in
this section of the service manual and replace as
required. Refer to BALL JOINT in this section of this
service manual group.
BALL JOINT
With the weight of the vehicle resting on the road
wheels, grasp the headless grease fitting as shown
(Fig. 4). With no mechanical assistance or added
force, attempt to move the grease fitting. If the ball
joint is worn, the grease fitting will move. If move-
ment is noted, replace the ball joint.

DIAGNOSIS AND TESTING (Continued)

CAUTION: No attempt should be made to service
the headless grease fitting on the ball joint. It has
been purposely snapped off by the manufacturer to
avoid over-greasing.
STABILIZER BAR (FRONT)
Inspect for broken, cracked or distorted stabilizer
bar cushions and retainers. Inspect for worn or dam-
aged stabilizer bar links (Fig. 1).
SERVICE PROCEDURES
LUBRICATION
There are no serviceable lubrication points on the
front suspension. The front lower ball joints have
grease fittings which have had the head snapped off
by the manufacturer after they have been filled. This
has been done to eliminate the possibility of damag-
ing the non-vented seals. Grease will not leak from
the broken grease fittings. The ball joints are sealed
for life and require no maintenance.
CAUTION: No attempt should be made to replace
the ball joint grease fitting with a new fitting, then
filling the ball joint with grease. Damage to the
grease seal can result.
REMOVAL AND INSTALLATION
SERVICE WARNINGS AND CAUTIONS
WARNING: DO NOT REMOVE THE STRUT SHAFT
NUT WHILE STRUT ASSEMBLY IS INSTALLED IN
VEHICLE, OR BEFORE THE COIL SPRING IS COM-
PRESSED WITH A COMPRESSION TOOL. THE
SPRING IS HELD UNDER HIGH PRESSURE.
CAUTION: Only frame contact hoisting equipment
can be used on this vehicle. All vehicles have a
fully independent rear suspension. The vehicles
cannot be hoisted using equipment designed to lift
a vehicle by the rear axle. If this type of hoisting
equipment is used, damage to rear suspension
components will occur.
CAUTION: At no time when servicing a vehicle can
a sheet metal screw, bolt, or other metal fastener be
installed in the shock tower to take the place of an
original plastic clip. It may come into contact with
the strut or coil spring.CAUTION: Wheel bearing damage will result if after
loosening the hub nut, the vehicle is rolled on the
ground or the weight of the vehicle is allowed to be
supported by the tires for a length of time.
