sealing boot on the upper control arm ball joint
assembly. Damage to the sealing boot can occur do
to excessive pressure applied to sealing boot when
being installed.
(3) Position Receiving Cup, Special Tool 6758 over
sealing boot so it is aligned properly with bottom
edge of sealing boot (Fig. 73). Apply pressure BY

DISASSEMBLY AND ASSEMBLY (Continued)
CAUTION: Under no circumstances can a lower ball
joint seal boot be replaced if it is determined that
the vehicle had been driven with the seal boot dam-
aged. If the vehicle has been driven with a damaged
seal boot contamination of the ball joint has
occurred. When contamination of the ball joint has
occurred the lower control arm must be replaced.
This is to ensure excessive wear of the ball joint
does not occur from the contamination present in
the ball joint.
CAUTION: Excessive wear in the ball joint can lead
to a separation of the ball joint from the lower con-
trol arm.
CAUTION: The procedure below must be carefully
followed when replacing the ball joint seal in the
event it is damaged while servicing a vehicle.
CAUTION: The ball joint used in the lower control
arm of this vehicle is a lubricated for life ball joint.
This ball joint does not required any additional
lubrication for the life of the vehicle. Do not alter
the lower control arm or ball joint in an attempt to
lubricate the lower control arm ball joint. If it is
determined that the ball joint is lacking proper lubri-
cation, the lower control arm will need to be
replaced.
DISASSEMBLE
(1) Remove lower control arm assembly from vehi-
cle. See Lower Control Arm Removal in this section
of the service manual for the required removal proce-
dure.
(2) Wrap a shop towel around the ball joint and
seal boot. This is to prevent dirt and cleaning solvent
to enter ball joint when cleaning area around ball
joint.
(3) Using ONLY a solvent such as Mopar Foamy
Engine Degreaser or an equivalent, thoroughly clean
lower control arm in area around ball joint and seal.
Then using a shop towel saturated with the engine
degreaser, carefully wipe off the ball joint seal boot.

75). Be sure no grease is present on the seal boot
installation section of the seal boot or lower control
arm (Fig. 75).
(2) Slide ball joint seal boot with upper seal ring
installed, (Fig. 75) down tapered section of ball joint
stud (Fig. 75). Seal boot is to be installed on stud of
