DESCRIPTION AND OPERATION (Continued)
COIL SPRING
Coil springs are rated separately for each corner or
side of the vehicle depending on optional equipment
and type of vehicle service. During service procedures
when both springs are removed, mark springs to
ensure installation in original position. Each coil
spring comes with a plastic sleeve on the second coil
of the spring. This plastic sleeve is a noise insulator
for the coil spring.
NOTE: If coil springs require replacement, be sure
that the springs needing replacement, are replaced
with springs meeting the correct load rating for the
vehicle and its specific options.
BALL JOINT
The ball joint (Fig. 2) is pressed into the lower con-
trol arm. The ball joint has a non-tapered stud with
a notch (Fig. 2) to provide clearance for the steering
knuckle clamp bolt and to provide retention of the
ball stud in the steering knuckle. The ball joint stud
is clamped and locked into the steering knuckle leg
using a pinch bolt. The ball joint used on this vehicle
is replaceable and if found defective can be serviced
as a separate component of the lower control arm
assembly.

WHEEL MOUNTING STUDS
If wheel attaching studs need to be replaced in the
hub and bearing assembly the studs CAN NOT be
hammered out of the hub flange. If a stud is removed
by hammering it out of the bearing flange, damage to
the hub and bearing assembly will occur leading to
premature bearing failure.
Use the procedure and special tools shown in the
service procedures section for the wheel mounting
studs when replacing the wheel attaching studs.
The hub and bearing assembly does not require
removal from the steering knuckle or the rear
knuckle to replace the wheel attaching studs in the
hub and bearing assembly.
DIAGNOSIS AND TESTING
Mc PHERSON STRUT
(1) Inspect for damaged or broken coil springs (Fig. 3).
(2) Inspect for torn or damaged strut assembly
dust boots (Fig. 3).
(3) Inspect the coil spring isolator on the lower
spring seat, (Fig. 3) for any signs of damage or dete-
rioration.
Fig. 3 Mc Pherson Strut Assembly Inspection
(4) Lift dust boot (Fig. 4) and inspect strut assembly for
evidence of fluid running from the upper end of fluid res-
ervoir. (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. 4). Also inspect jounce bumpers for
signs of damage or deterioration.
