DISASSEMBLY AND ASSEMBLY
McPHERSON STRUT
DISASSEMBLY
(1) Clamp the strut assembly in a vise, with the
strut in a vertical position.When clamping the
strut assembly in the vise, do not clamp strut
using the body of the strut only by strut clevis
bracket (Fig. 67).
(2) Mark coil spring and strut assembly right or
left, according to which side of the vehicle the strut
was removed from, and which strut coil spring was
removed from.
WARNING: DO NOT REMOVE STRUT ROD NUT,
BEFORE STRUT ASSEMBLY COIL SPRING IS COM-
PRESSED, REMOVING SPRING TENSION FROM
UPPER SPRING SEAT AND BEARING ASSEMBLY.
WARNING: WHEN COMPRESSING COIL SPRING
FOR REMOVAL FROM STRUT ASSEMBLY, THE
FIRST FULL TOP AND BOTTOM COIL OF THE COILSPRING MUST BE CAPTURED BY THE JAWS OF
THE COIL SPRING COMPRESSOR (Fig. 68).
(3) Compress the strut assembly coil spring, using
Spring Compressor, Special Tool C-4838 (Fig. 68).
(4) Install Socket, Strut Nut, Special Tool L-4558A
(or L-4558) on the strut shaft retaining nut (Fig. 69).
Then install a 10 mm socket on the hex of the strut
damper shaft (Fig. 69). While holding strut shaft
from turning, remove the strut shaft retaining nut.
(5) Remove the strut assembly mount/isolator (Fig.
70) from the strut.
(6) Remove the upper spring seat, pivot bearing
and dust shield as an assembly (Fig. 71) from the
strut.

(7) Remove the jounce bumper (Fig. 72) from the
shaft of the strut assembly.(8) Remove the coil spring from the strut assembly
(Fig. 73).Mark left and right on the coil springs
for their installation back on the correct side of
the vehicle.
WARNING: IF A REPLACEMENT COIL SPRING IS
TO BE INSTALLED ON THE STRUT ASSEMBLY, THE
FIRST FULL TOP AND BOTTOM COIL OF THE
SPRING MUST BE CAPTURED BY THE JAWS OF
THE COIL SPRING COMPRESSOR.
(9) Inspect the strut for any binding of the strut
shaft over the full stroke of the shaft.
(10) Inspect the strut mount and the upper spring
seat assembly (Fig. 74) for any of the following con-
ditions:
²Mount for cracks and distortion and retaining
studs for any sign of damage.
²Severe deterioration of rubber isolator,

²Binding strut assembly pivot bearing. If pivot
bearing is replaced it is to be installed with the white
side of bearing facing up (Fig. 74).
²Inspect dust shield for rips and/or deterioration.
²Inspect jounce bumper for cracks and signs of
deterioration.
(11) Replace any components of the strut assembly
found to be worn or defective during the inspection,
before assembling the strut.
ASSEMBLE
(1) Clamp the strut assembly in a vise, with the
strut in a vertical position.When clamping the
strut assembly in the vise, do not clamp strut
using the body of the strut only by strut clevis
bracket (Fig. 67).
(2) Install the compressed coil spring onto the
strut. Coil spring is to be installed with smaller coil
down, so spring correctly seats on strut assembly
(Fig. 73).
(3) Install jounce bumper on the strut shaft (Fig.
72).
(4) Install dust shield, pivot bearing and upper
spring seat as an assembly on the strut (Fig. 71).
(5) Position upper spring seat alignment notch
with clevis bracket on strut assembly.
(6) Install strut mount on strut assembly (Fig. 70)
and the strut mount retaining nut on the shaft of the
strut assembly.
WARNING: THE FOLLOWING 2 STEPS MUST BE
COMPLETELY DONE BEFORE SPRING COMPRES-
SOR, SPECIAL TOOL C-4838 IS RELEASED FROM
THE COIL SPRING.
(7) Install Socket, Strut Nut, Special Tool L-4558A
(or L-4558) on the strut shaft retaining nut (Fig. 69).
Then install a 10 mm socket through the center of
the socket and on the hex of the strut shaft (Fig. 69).
While holding strut shaft from turning, torque strut
shaft retaining nut to 75 N´m (55 ft. lbs.).
(8) Equally loosen both Spring Compressors, Spe-
cial Tool C-4838 until top coil of spring is fully seated
against upper spring seat and strut mount. Then
relieve all tension from spring compressors and
remove spring compressors from strut assembly
spring.
BALL JOINT
DISASSEMBLE
(1) Using a screw driver or other suitable tool, pry
seal boot off of ball joint assembly (Fig. 75).
(2) Position Receiving Cup, Special Tool 6758 to
support lower control arm while receiving ball joint
assembly (Fig. 76). Install Remover/Installer, Special
Tool 6804 in top of ball joint assembly (Fig. 76).(3) Using arbor press, press ball joint assembly
completely out of lower control arm.
ASSEMBLE
CAUTION: When installing ball joint in its mount-
ing hole in lower control arm, position ball joint so
notch in ball joint stud is facing the front lower con-
trol arm bushing. This will ease assembly of ball
joint to steering knuckle when attempting to install
pinch bolt.
(1) By hand, position ball joint assembly into ball
joint bore of lower control arm. Be sure ball joint
assembly is not cocked in the bore of the control arm,
this will cause binding of the ball joint assembly,
when being pressed into lower control arm.
(2) Position assembly in an arbor press with
Receiving Cup, Special Tool 6758 supporting lower
control arm (Fig. 77). Then install Remover/Installer,
Special Tool 6804 on the bottom of the ball joint
assembly (Fig. 77).

(3) Carefully align all pieces. Using the arbor
press apply pressure against ball joint assembly (Fig.
77), until ball joint is fully seated against bottom sur-
face of lower control arm. Do not apply excessive
pressure against ball joint and lower control arm.
(4) Install aNEWball joint assembly sealing boot
on ball joint assembly. Install sealing boot as far as
possible on ball joint assembly.
CAUTION: Do not use an arbor press to install the
sealing boot on the lower control arm ball joint
assembly. Damage to the sealing boot can occur do
to excessive pressure applied to sealing boot when
being installed.
(5) Position Receiving Cup, Special Tool 6758 over
sealing boot so it is aligned properly with bottom
edge of sealing boot (Fig. 78). Apply pressureBY
HANDto special tool 6758, until sealing boot is
pressed squarely against top surface of lower control
arm.

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.
