Camber adjustment is allowed in the event that a
vehicle is involved in an accident and after repairs
are made meeting manufacturers tolerance specifica-
tions, the camber setting will not meet manufactur-
ers specifications. If camber adjustment is required,
refer to the following Service Camber Adjustment
Procedure for the required steps to be followed.
CAUTION: Do not attempt to modify any suspen-
sion or steering components to meet vehicle align-
ment specifications, by heating and or bending.
Alignment checks and adjustments should be made
in the following sequence.
(1) Camber
(2) ToeCamberis the number of degrees the top of the
wheel and tire assembly is tilted inboard or outboard
from a true vertical line. Inboard tilt is negative cam-
ber. Outboard tilt is positive camber (Fig. 1).
Excessive camber is a tire wear factor: negative
camber causes wear on the inside of the tires tread
surface, while positive camber causes wear to the
outside of the tires tread surface. See Front Wheel
Drive Specifications forCamber.settings.
To eis measured in degrees or inches and is the
distance the front edges of the tires are closer (or far-
ther apart) than the rear edges. See Front Wheel

DESCRIPTION AND OPERATION
FRONT SUSPENSION DESCRIPTION
An independent Mc Pherson Strut type front sus-
pension is used on these vehicles. Vertical shock
absorbing Mc Pherson Struts attach to the top of the
steering knuckle and to the front strut tower. This
interconnection between the steering knuckle and the
body of the vehicle, provides for the correct steering
knuckle position. This steering knuckle position pro-
vides for the correct front Caster and Camber set-
tings for the vehicle, at the time the vehicle is
designed.
Lower control arms are attached inboard to the
cast aluminum front suspension cradle and outboard
to the bottom of the steering knuckle. Attachment of
the lower control arm to the steering knuckle is done
through a ball joint in the lower control arm.
During steering maneuvers, the strut and the
steering knuckle (through the ball joint and a pivot
bearing in the strut's upper retainer) turn as an
assembly.
SUSPENSION CRADLE (CROSSMEMBER)
This vehicle uses a one piece cast aluminum cradle
for the front suspension. The cradle is used as theattaching points for the lower control arms, stabilizer
bar and steering gear. The cradle also has the power
steering hoses and the chassis brake tubes attached
to it.
The cradle is mounted to the front frame rails at
four points, two on each side of the vehicle. The cra-
dle is isolated from the body of the vehicle using four
isolators, one located at each mounting bolt location.
WARNING: If a threaded hole in the suspension
cradle needs to be repaired, only use the type of
thread insert and installation procedure specified
for this application.
The threaded holes in the cradle that are
used for attachment of the lower control arm
rear bushing retainer, power steering hose and
chassis brake tubes can be repaired. The repair
is done by the installation of a Heli-Coilt
thread insert which has been specifically devel-
oped for this application. Refer to the Mopar
Parts Catalog for the specified Heli-Coil thread
insert to be used for this application. The pro-
cedure for installing the Heli-Coiltthread
insert is detailed in the Service Procedures sec-
tion in this group of the service manual.
NSSUSPENSION 2 - 9

STEERING KNUCKLE
The front suspension knuckle is not a repairable
component of the vehicles front suspensionIT MUST
BE REPLACED.If bent, broken or damaged in any
way, do not attempt to straighten or repair the steer-
ing knuckle.
Service replacement of the front hub/bearing
assembly can be done with the front steering knuckle
remaining on the vehicle.
LOWER CONTROL ARM
If damaged, the lower control arm casting is ser-
viced only as a complete component. Inspect lower
control arm for signs of damage from contact with
the ground or road debris. If lower control arm shows
any sign of damage, inspect lower control arm for
distortion.Do not attempt to repair or straighten
a broken or bent lower control arm.
The serviceable components of the lower control
arm are: the ball joint assembly, ball joint assembly
grease seal and control arm bushings. Inspect both
control arm bushings for severe deterioration, and
replace if required. Inspect ball joint per inspection
procedure in this section of the service manual and
replace if required. Service procedures to replace
these components are detailed in the specific compo-
nent removal and installation sections in this group
of the service manual.
BALL JOINT (LOWER)
With the weight of the vehicle resting on the road
wheels, grasp the grease fitting as shown in (Fig. 5)
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 ball joint is recommended.
STABILIZER BAR
Inspect for broken or distorted sway bar bushings,
bushing retainers, and worn or damaged sway bar to
strut attaching links. If sway bar to front suspension
cradle bushing replacement is required, bushing can
be removed from sway bar by opening slit and peel-
ing bushing off sway bar.
HUB AND BEARING ASSEMBLY
The condition of the front hub and bearing assem-
bly is diagnosed using the inspection and testing pro-
cedure detailed below.
The bearing contained in the Unit III front hub/
bearing assembly will produce noise and vibration
when worn or damaged. The noise will generally
change when the bearings are loaded. A road test of
the vehicle is normally required to determine the
location of a worn or damaged bearing.
Find a smooth level road surface and bring the
vehicle up to a constant speed. When vehicle is at a
constant speed, swerve the vehicle back and forth
from the left and to the right. This will load and
unload the bearings and change the noise level.
Where axle bearing damage is slight, the noise is
usually not noticeable at speeds above 30 m.p.h..
SERVICE PROCEDURES
SUSPENSION CRADLE THREAD REPAIR
PROCEDURE
WARNING: When performing this procedure use
only the thread inserts which are specified in the
Mopar Parts Catalog for this repair procedure.
These thread inserts have been specifically devel-
oped for this application and use of other types of
thread inserts can result in an inferior long term
repair.
The threaded holes in the front suspension cradle,
if damaged, can repaired by installing a Heli-Coilt
thread insert.
The threaded holes that are repairable using the
thread insert, are the lower control arm rear bushing
retainer mounting bolt holes, routing bracket attach-
ing locations for the power steering hoses, and brake
hose attachment holes.
This repair procedure now allows the threaded
holes in the suspension crossmember to be repaired,
eliminating the need to replace the crossmember if
damage occurs to one of the threaded holes.
The thread inserts for this application are specified
by part number in the Mopar Parts Catalog.Do not
use a substitute thread insert.
The specific tools and equipment required to install
the thread insert are listed below. Refer to the
