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.

STRUT
DESCRIPTION - STRUT ASSEMBLY
A Macpherson type strut assembly is used in place
of a conventional front suspension's upper control
arm and upper ball joint. The bottom of the strut
mounts directly to the steering knuckle using two
bolts and nuts going through the strut clevis bracket
and steering knuckle. The top of the strut mounts
directly to the strut tower of the vehicle using the
threaded studs on the strut assemblies upper mount.
The strut assembly includes the components listed
in the figure (Fig. 38).
Each component is serviced by removing the strut
assembly from the vehicle and disassembling it.
The coil springs are side-oriented. Springs on the
left side of the vehicle have a left-hand wind top-to-

bottom while springs on the right side have a right-
hand wind top-to-bottom. This helps provide better
vehicle stability during jounce and rebound maneu-
vers of the front suspension. Left and right springs
must not be interchanged. Coil springs are rated sep-
arately for each corner or side of the vehicle depend-
ing on optional equipment and type of vehicle
service. If the coil springs require replacement, be
sure that the springs are replaced with springs meet-
ing the correct load rating and spring rate for the
vehicle and its specific options.
OPERATION - STRUT ASSEMBLY
The strut assembly cushions the ride of the vehicle,
controlling vibration, along with jounce and rebound
of the suspension.
The coil spring controls ride quality and maintains
proper ride height.
The spring isolators isolate the coil spring at the
top and bottom from coming into metal-to-metal con-
tact with the upper seat and strut.
The jounce bumper limits suspension travel and
metal-to-metal contact under full jounce condition.The strut dampens jounce and rebound motions of
the coil spring and suspension.
During steering maneuvers, the strut assembly
(through a pivot bearing in the upper strut mount)
and steering knuckle (through the lower ball joint)
turn as an assembly.
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.

WARNING: DO NOT REMOVE THE STRUT SHAFT
NUT BEFORE THE COIL SPRING IS COMPRESSED.
THE COIL SPRING IS HELD UNDER PRESSURE
AND MUST BE COMPRESSED, REMOVING SPRING
TENSION FROM THE UPPER MOUNT AND PIVOT
BEARING, BEFORE THE SHAFT NUT IS REMOVED.(1) Position the strut assembly in the strut coil
spring compressor following the manufacturers
instructions. Position the lower hooks on the coil
spring first. The strut clevis bracket should be posi-
tioned straight outward from the compressor.
(2) Turn the upper mount of the strut assembly
toward the inside of the compressor as shown to
allow positioning of the compressor upper hooks (Fig.
44). Position the upper hooks on top of the coil spring
upper seat approximately 1 inch from outside diame-
ter of seat (Fig. 47).Do not allow hooks to be
placed closer to edge.Place a clamp on the lower
end of the coil spring, so the strut is held in place
once the strut shaft nut is removed.
(3) Compress the coil spring until all coil spring
tension is removed from the upper mount.
(4) Install Strut Nut Socket, Special Tool 6864, on
the strut shaft retaining nut (Fig. 45). Next, install a
10 mm socket on the hex on the end of the strut
shaft. While holding the strut shaft from turning,
remove the nut from the strut shaft.
(5) Remove the upper mount from the strut shaft.
(6) If the pivot bearing needs to be serviced,
remove it from the top of the coil spring upper seat
by pulling it straight up.
(7) Remove the clamp from the bottom of the coil
spring and remove the strut out through the bottom
of the coil spring.
NOTE: If the coil spring or upper spring seat needs
to be serviced, proceed with the next step, other-
wise, proceed with step 10.

HUB / BEARING
DESCRIPTION
The rear wheel bearing and rear wheel hub of this
vehicle are a one-piece sealed unit, or hub and bear-
ing unit type assembly (Unit III). The hub and bear-
ing is mounted to the center of the rear axle using 4
mounting bolts. It has five wheel mounting studs on
the hub flange.
All-Wheel-Drive vehicles have a hub and bearing
unit with a splined hole in the center of the hub for
rear driveshaft stub axle acceptance.
Front-Wheel-Drive vehicles with antilock brakes
have an internally mounted wheel speed sensor and
tone wheel. This hub and bearing can be identified
by the rounded cap and molded in connector on the
rear of the assembly (Fig. 7). The sensor and tone
wheel cannot be serviced separately from the hub
and bearing.
OPERATION
The hub and bearing has internal bearings that
allow the hub to rotate with the tire and wheel
assembly (and driveshaft on All-Wheel-Drive vehi-
cles). The five wheel mounting studs mount the tire
and wheel assembly, and disc brake rotor or brake
drum to the vehicle.
