HUB / BEARING
DESCRIPTION
The front wheel bearing and front wheel hub of
this vehicle are a hub and bearing unit type assem-
bly (Unit III). This unit combines the front wheel
mounting hub (flange) and the front wheel bearing
into a sealed one-piece unit. The hub and bearing is
mounted to the center of the steering knuckle (Fig.
1). It is retained by four mounting bolts accessible
from the inboard side of the steering knuckle. The
hub flange has five wheel mounting studs.
The wheel mounting studs used to mount the tire
and wheel to the vehicle are the only replaceable
components of the hub and bearing assembly. Other-
wise, the hub and bearing is serviced only as a com-
plete assembly.
OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the driveshaft, along
with the tire and wheel. The five wheel mounting
studs mount the tire and wheel, and brake rotor to
the vehicle.
DIAGNOSIS AND TESTING - HUB AND
BEARING
The condition of the front hub and bearing assem-
bly is diagnosed using the inspection and testing pro-
cedure detailed below.
The bearing contained in the Unit III front hub/
bearing assembly will produce noise and vibration
when worn or damaged. The noise will generally
change when the bearings are loaded. A road test of
the vehicle is normally required to determine the
location of a worn or damaged bearing.
Find a smooth level road surface and bring the
vehicle up to a constant speed. When vehicle is at a
constant speed, swerve the vehicle back and forth
from the left and to the right. This will load and
unload the bearings and change the noise level.
When bearing damage is slight, the noise is some-
times noticeable at lower speeds and at other times
is more noticeable at speeds above 105 km/h (65
mph).
REMOVAL
NOTE: Replacement of the Unit III front hub/bearing
assembly can be normally done without having to
remove the steering knuckle from the vehicle. In the
event that the hub/bearing is frozen in the steering
knuckle and cannot be removed by hand, it will
have to be pressed out of the steering knuckle. The
steering knuckle will require removal from the vehi-
cle to allow the hub/bearing assembly to bepressed out of the steering knuckle. (Refer to 2 -

LOWER BALL JOINT
DESCRIPTION
The ball joint is an integral part of the lower con-
trol arm (Fig. 1). The ball joint has a tapered stud
that is pressed into the aluminum knuckle. The ball
joint stud is threaded on the end for a retainer nut.
The ball joint has a non-vented seal boot. The seal
boot has an integrated heat shield.
The ball joint used in the lower control arm of this
vehicle is a sealed-for-life ball joint and requires no
maintenance lubrication. The ball joint has been
lubricated-for-life during the manufacturing process.
A special fitting cap is installed on the fill port. This
cap must not be removed and replaced with a com-
mon zirc fitting. The special cap is there to eliminate
the possibility of lubrication latter during the ball
joints life, thus damaging the non-vented seal boot.
NOTE: The ball joint does not require any type of
additional lubrication for the life of the vehicle. No
attempt should be made to ever add any lubrication
to the lower ball joint.
OPERATION
The ball joint is a pivotal joint on the lower control
arm that allows the knuckle to move up and down,
and turn with ease.
DIAGNOSIS AND TESTING - LOWER BALL
JOINT
With the weight of the vehicle resting on the road
wheels, grasp the special fitting cap on the bottom of
the ball joint and with no mechanical assistance or
added force, attempt to rotate the grease fitting.
If the ball joint is worn, the grease fitting will
rotate easily. If movement is noted, replacement of
the control arm is recommended.
LOWER BALL JOINT SEAL
BOOT
DESCRIPTION - EXPORT
The lower ball joint seal boot is a two piece unit. It
consists of the seal boot, plus a separate shield that
is located in a groove at the top of the seal boot.
NOTE: The seal boot should only be replaced if
damaged during vehicle service. The entire lower
control arm should be replaced if the joint has been
contaminated.

LOWER CONTROL ARM
DESCRIPTION
The lower control arm is mounted to the front sus-
pension crossmember using a pivot bolt through the
center of the front pivot bushing, and the front sus-
pension cradle crossmember reinforcement traps the
rear bushing in the crossmember (Fig. 1).
The lower control arm is an iron casting with two
rubber bushings and a ball joint. The lower control
arm front bushing is the spool type and is pressed
into the lower control arm. The standard (Low-line)
lower control arm rear bushing is a push-on bushing
that is pushed over a stem on the rear of the lower
control arm. The optional (High-line, Premium,
Sport) lower control arm rear bushing is a hydro-
bushing that is pressed on. It has liquid filled voids
that provide more effective dampening than the stan-
dard bushing. Vehicles with rear hydro-bushings uti-
lize a different lower control arm than vehicles with
standard bushings. They have a straight slightly
tapered round stem where the hydro-bushing is
mounted whereas the standard arm has a straight
stem with a squared knob on the end to retain the
bushing.
The lower control arm ball joint is pressed into the
outer end of the arm. The ball joint has a tapered
stud and retainer nut for fastening it to the steering
knuckle.
OPERATION
The lower control arm supports the lower end of
the steering knuckle and allows for the up and down
movement of the suspension during the jounce and
rebound travel. The lower control arm ball joint con-
nects the arm to the steering knuckle.
REMOVAL - LOWER CONTROL ARM
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)

DIAGNOSIS AND TESTING - STRUT ASSEMBLY
(1) Inspect for damaged or broken coil springs
(Fig. 38).
(2) Inspect for torn or damaged strut assembly
dust boots (Fig. 38).
(3) Inspect the coil spring isolator on the lower
spring seat for any signs of damage or deterioration.
(4) Lift dust boot (Fig. 39) and inspect strut
assembly for evidence of fluid running from the
upper end of fluid reservoir. (Actual leakage will be a
stream of fluid running down the side and dripping
off lower end of unit). A slight amount of seepage
between the strut rod and strut shaft seal is not
unusual and does not affect performance of the strut
assembly (Fig. 39). Also inspect jounce bumpers for
signs of damage or deterioration.
