ADJUSTMENTS
STRUT ADJUSTMENT COMPETITION PACKAGE
SUSPENSION
The front struts used on a vehicle equipped with
the competition package are adjustable. The adjust-
able front struts use a unique strut shaft with an
adjustment rod through the center of it (Fig. 89). The
adjustment rod is used to adjust the compression
dampening of the strut.
The compression dampening of the strut is adjusted
using the adjustment knob (Fig. 90) which is supplied
with the vehicle at the time of purchase. The adjust-
ment is done by inserting the flat on the end of the
adjustment rod into the grove on the adjustment knob
(Fig. 91). The compression dampening is increased by
rotating the adjustment knob in a counterclockwise
direction and decresed by rotating the adjustment knob
in a clockwise direction (Fig. 90).

GENERAL INFORMATION
GENERAL INFORMATION
CAUTION: Only frame contact or wheel lift hoisting
equipment can be used on vehicles having a fully
independent rear suspension. Vehicles with inde-
pendent rear suspension can not be hoisted using
equipment designed to lift a vehicle by the rear
axle. If this type of hoisting equipment is used dam-
age to rear suspension components will occur.
NOTE: If a rear suspension component becomes
bent, damaged or fails, no attempt should be made
to straighten or repair it. Always replace with a new
component.
DESCRIPTION AND OPERATION
REAR SUSPENSION
The rear suspension system used on this vehicle is
a fully independent type rear suspension system (Fig.
1).A forged rear knuckle is bolted to each rear strut.
The movement of the rear knuckle is controlled lat-
erally using lateral links going from the front and
rear of the knuckle to the rear crossmember. Fore
and aft movement of the knuckle is controlled by a
tension strut.
The lateral links and tension strut have rubber iso-
lator bushings at each end. The lateral links are
attached to the rear crossmember and knuckle, using
a common bolt and nut assembly at each end. The
tension strut bolts to the bottom of the knuckle and
to a bracket attached to the floor pan of the vehicle.
The lateral links, tension strut and spindle are
normally replaced only when the part has been dam-
aged or when the vehicle has been involved in an
accident. If a suspension part has been damaged, be
sure to check the underbody dimensions of the car. If
the underbody dimensions are not correct, the frame
of the vehicle must be straightened, before replace-
ment suspension components are installed.
PLSUSPENSION 2 - 39

COMPETITION PACKAGE SUSPENSION
On vehicles that are equipped with the optional
competition package, special rear struts are used.
The rear struts used on a vehicle equipped with
the competition package are adjustable. The adjust-
able struts use a unique strut shaft which has an
adjustment rod through the center of it (Fig. 2). The
adjustment rod is used to adjust the compression
dampening of the strut. By increasing the compres-
sion dampening of the strut, the jounce reaction of
the strut is slowed down. This slowing down of the
jounce reaction of the strut, stiffens the suspension
thus improving the handling of the vehicle.
The compression dampening of the strut is
adjusted using the adjustment knob (Fig. 3) which is
supplied with the vehicle at the time of purchase.
STRUT
The rear strut assemblies support the weight of
the vehicle using coil springs positioned around the
struts. The coil springs are contained between theupper mount of the strut assembly and a lower
spring seat on the body of the strut assembly.
The top of each strut assembly is bolted to the top
of the inner fender through a rubber isolated mount.
The bottom of the strut assembly attaches to the
rear knuckle using 2 thru-bolts and prevailing torque
nuts. Rear Caster and camber on this vehicle is a
fixed setting (net build) and is not required to be
adjusted as a normal procedure when performing an
alignment on this vehicle.
COIL SPRING
Rear coil springs are rated separately for each cor-
ner or side of the vehicle depending on optional
equipment and type of vehicle service. During service
procedures when both rear coil springs are removed,
mark the coil springs to ensure installation of the
springs in their original position.If coil springs
require replacement, be sure the springs need-
ing replacement, are replaced with springs
meeting the correct load rating for the vehicle
and its specific options.
STABILIZER BAR
The stabilizer bar interconnects both rear strut
assemblies and is attached to the rear frame rails of
the vehicle.
Jounce and rebound movements affecting one
wheel are partially transmitted to the opposite wheel
of the vehicle to stabilize body roll.
Attachment of the stabilizer bar to the rear frame
rails of the vehicle is through 2 rubber-isolator bush-
ings and bushing retainers. The stabilizer bar to
strut assembly attachment is done utilizing a rubber
isolated stabilizer bar attaching link. All parts of the
stabilizer bar are serviceable, and the stabilizer bar
to frame rail isolator bushings are split for easy
removal and installation. The split in the stabilizer
bar to crossmember bushing must be positioned
toward the rear of the vehicle, when the stabilizer
bar is installed on the vehicle.
KNUCKLE
A forged rear knuckle bolts to each rear strut
assembly. The movement of the rear knuckle is con-
trolled laterally using two lateral arms attached to
the knuckle. The outboard ends of the two lateral
arms are mounted forward and rearward of the spin-
dle centerline, and inboard ends are mounted to the
rear crossmember. Fore and aft movement of the
knuckle is controlled by using a tension strut.
LATERAL LINKS AND TENSION STRUTS
The lateral arms and tension strut have rubber
isolator bushings at each end. The lateral arms are
attached to the rear crossmember and knuckle, using
Fig. 2 Adjustable Front Strut
Fig. 3 Adjustable Strut Adjustment Knob
PLSUSPENSION 2 - 41
DESCRIPTION AND OPERATION (Continued)

a unique bolt and nut assembly at each end. The lat-
eral arm to rear crossmember attaching bolts are
longer than the lateral arm to knuckle attaching
bolts. Each lateral arm to knuckle attaching bolt and
nut assembly uses 2 flat washers. Each lateral arm
to rear crossmember attaching bolt uses 1 flat
washer and 1 adjustment cam to provide a means for
rear wheel Toe adjustment. The tension strut assem-
bly attaches to a bracket on the frame rail and to the
bottom of the knuckle.
Lateral arms, tension struts and knuckles are nor-
mally replaced only when the part has been damaged
or when the vehicle has been involved in an accident.
If a suspension part has been damaged, be sure to
check the underbody dimensions of the car. If under-
body dimensions of the vehicle are not correct, the
frame must be straightened before replacement sus-
pension components are installed.
DIAGNOSIS AND TESTING
STRUT INSPECTION (ON VEHICLE)
(1) Inspect for damaged or broken coil springs
(Fig. 4).
(2) Inspect for torn or damaged strut assembly
dust boots (Fig. 4).
(3) Inspect for damaged lower spring isolator (Fig.
4).
(4) Lift dust boot 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 ofunit). 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. 5). Also
inspect jounce bumpers for signs of damage or dete-
rioration.
KNUCKLE
The rear knuckle is not a repairable component of
the rear suspension. If it is determined that the
knuckle is cracked, bent or broken when servicing
the vehicle, no attempt is to be made to repair or to
straighten the knuckle.THE KNUCKLE MUST BE
REPLACED IF FOUND TO BE DAMAGED IN
ANY WAY.
LATERAL LINKS
Inspect the lateral link isolator bushings and
sleeves for signs of damage or deterioration. If the
lateral link isolator bushings or sleeves are damaged
or are deteriorated, replacement of the lateral link
assembly will be required. The isolator bushings are
not serviceable as a separate component of the lat-
eral link assembly.
Inspect the lateral links for signs of contact with
the ground or road debris which has bent or caused
other damage to the lateral link assembly. If the lat-
eral link is bent or damaged, the lateral link will
require replacement.Do not attempt to repair or
straighten a lateral link.
TENSION STRUT
Inspect the tension strut bushings and retainers
for signs of deterioration or damage. If the tension
strut bushings are deteriorated or the retainers are
damaged, replacement of the tension strut bushings
and or the retainers will be required. The bushings
and retainers are serviceable as separate components
of the tension strut.

DESCRIPTION AND OPERATION (Continued)

Inspect the tension strut for signs of contact with
the ground or road debris which has bent or caused
other damage to the tension strut. If the tension
strut is bent or damaged the tension strut will
require replacement.Do not attempt to repair or
straighten a tension strut.
STABILIZER BAR AND BUSHINGS
Inspect the stabilizer bar for damage or bending.
Inspect for broken or distorted stabilizer bar bush-
ings, bushing retainers, and worn or damaged stabi-
lizer bar to strut attaching links. If stabiizer bar to
rear frame rail bushing replacement is required,
bushings can be removed from sway bar by opening
slit and peeling bushing off sway bar.
STABILIZER BAR ATTACHING LINKS
Inspect the bushings and sleeves in the stabilizer
bar attaching links for damage or deterioration.
Inspect the stabilizer bar attaching link to ensure it
is not bent or broken. If any of these conditions are
present when inspecting the attaching links, replace-
ment of the attaching link is required.
