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.
