DESCRIPTION AND OPERATION
GENERAL INFORMATION
Wheel alignment is the proper adjustment of all
the interrelated suspension angles affecting the run-
ning and steering of the front and rear wheels of the
vehicle.
The method of checking front and rear wheel align-
ment will vary depending on the type of equipment
being used. The instructions furnished by the manu-
facturer of the equipment should always be followed.
With the exception that the wheel alignment specifi-cations recommended by Chrysler Corporation should
always be used. The Chrysler Corporation recom-
mended alignment specifications, are listed in Speci-
fications at the end of this group in the service
manual section.
There are six basic factors which are the founda-
tion to front wheel alignment. These are vehicle
height, caster, camber, toe-in, steering axis inclina-
tion and toe-out on turns. Of the six basic factors
only toe-in is normally mechanically adjustable on
this vehicle (Fig. 1).

PRE-WHEEL ALIGNMENT INSPECTION
Before any attempt is made to change or correct
the wheel alignment factors. The following part
inspection and the necessary corrections should be
made to those parts which influence the steering of
the vehicle.
(1) Check and inflate all tires to recommended
pressure. All tires should be the same size and in
good condition and have approximately the same
wear. Note the type of tread wear which will aid in
diagnosing, see Wheels and Tires, Group 22.
(2) Check front wheel and tire assembly for radial
runout.
(3) Inspect lower ball joints and all steering link-
age for looseness.
(4) Check for broken or sagged front and rear
springs.(5) Check vehicle ride height to verify it is within
specifications.
(6) AlignmentMUSTonly be checked after the
vehicle has the following areas inspected and or
adjusted. Recommended tire pressures, full tank of
fuel, no passenger or luggage compartment load and
is on a level floor or a properly calibrated alignment
rack.
SERVICE PROCEDURES
WHEEL ALIGNMENT CHECK AND ADJUSTMENT
PROCEDURE
CASTER AND CAMBER
Front suspension Caster and Camber settings on
this vehicle are determined at the time the vehicle is
designed. This is done by determining the precise
2 - 4 SUSPENSIONNS
DIAGNOSIS AND TESTING (Continued)
mounting location of the vehicle's suspension compo-
nents throughout the design and assembly processes
of the vehicle. This is called a Net Build vehicle and
results in no normal requirement to adjustment the
Caster and Camber after a vehicle is built or when
servicing the suspension components. Thus Caster
and Camber are not normally considered an adjust-
able specification when performing an alignment on
this vehicle. Though Caster and Camber are not
adjustable they should be checked during the align-
ment procedure to ensure they meet the manufactur-
ers specifications.
If front camber does not meet the vehicle align-
ment specifications, it can be adjusted using a Mopar
Service Kit developed to allow for camber adjust-
ment. If a vehicle's front camber does not meet
required specifications, the vehicles suspension com-
ponents should be inspected for any signs of damage
or bending and the vehicle ride height should be
checked to verify it is within required specification.
This inspection must be done before using the
Mopar Service Kit for setting camber to the
vehicle specification.
CAUTION: Do not attempt to adjust the vehicles
Caster or Camber by heating, bending or by per-
forming any other modification to the vehicle's front
suspension components.
(1) Correctly position the vehicle on the alignment
rack. Then install all required alignment equipment
on the vehicle, per the alignment equipment manu-
facturers specifications.
NOTE: Prior to reading each alignment specifica-
tion, front and rear of vehicle should be jounced an
equal number of times. Induce jounce (rear first
then front) by grasping center of bumper and jounc-
ing each end of vehicle an equal number of times.
Bumper should always be released when vehicle is
at the bottom of the jounce cycle.
(2) Correctly jounce vehicle and then read the
vehicle's current front and rear alignment settings.
Compare the vehicle's current alignment settings to
the vehicle specifications for camber, caster and Toe-
in. See Alignment Specifications in this group of the
service manual for the required specifications.If
front and rear camber readings are within
required specifications proceed to step Step 3
for the Toe-in adjustment procedure if
required. If Camber readings are not within
specifications refer to step Step 1 in the front
camber adjustment cam bolt adjustment proce-
dure.CAMBER ADJUSTMENT CAM BOLT PACKAGE INSTALLATION
PROCEDURE
(1) If the front camber readings obtained are not
within the vehicle's specifications, use the following
procedure and the Mopar Clevis Bolt Service Kit to
provide camber adjustment. The kit contains 2 flange
bolts, 2 cam bolts, and 2 dog bone washers. These
components of the service kit are necessary to assem-
ble the strut to the steering knuckle, after modifica-
tion of the strut clevis bracket.
(2) Verify that the strut and steering knuckle are
not bent or otherwise damaged. If either component
is bent or show other signs of damage, replace
required component(s) and check the camber setting
again. Refer to Strut Damper Assembly Service in
this group of the service manual for the required
strut replacement procedure.
(3) If no component is bent or damaged, use the
following procedure for modifying the strut clevis
bracket and adjusting the camber setting.
(4) Raise front of vehicle until tires are not sup-
porting the weight of the vehicle. Then remove wheel
and tire assembly from the location on the vehicle
requiring the strut to be modified.
CAUTION: When removing the steering knuckle
from the strut clevis bracket, do not put a strain on
the brake flex hose. Also, do not let the weight of
the steering knuckle assembly be supported by the
brake flex hose when removed from the strut
assembly. If necessary use a wire hanger to sup-
port the steering knuckle assembly or if required
remove the brake flex hose from the caliper assem-
bly.
CAUTION: The steering knuckle strut assembly
attaching bolts are serrated and must not be turned
during removal. Remove nuts while holding bolts
stationary in the steering knuckles.
(5) Remove the top and bottom, strut clevis
bracket to steering knuckle attaching bolts (Fig. 2)
and discard. Separate the steering knuckle from the
strut clevis bracket and position steering knuckle so
it is out of the way of the strut.
CAUTION: When slotting the bottom mounting
hole on the strut clevis bracket, do not enlarge the
hole beyond the indentations (Fig. 3) on the sides
of the strut clevis bracket.

SERVICE PROCEDURES (Continued)
(11) When vehicle is at correct camber setting
torque both front strut to steering knuckle attaching
bolts to 90 N´m (65 ft. lbs.) plus an additional 1/4
turn after required torque is met.
(12) If Toe readings obtained are not within the
required specification range, adjust Toe to meet the
preferred specification setting. Toe is adjustable
using the following Toe setting procedure.
FRONT TOE SETTING PROCEDURE
(1) Prepare vehicle as described in the Pre-Align-
ment Vehicle Inspection procedure.
(2) Center steering wheel and lock in place using a
steering wheel clamp.
CAUTION: Do not twist front inner tie rod to steer-
ing gear rubber boots during front wheel Toe
adjustment.(3) Loosen front inner to outer tie rod end jam
nuts (Fig. 7). Grasp inner tie rods at serrations and
rotate inner tie rods of steering gear (Fig. 7) to set
front Toe to the preferred Toe specification. See
Alignment Specifications in this group of the service
manual for preferred specification.
(4) Tighten tie rod jam nuts (Fig. 7) to 75 N´m (55
ft.lbs.) torque.
(5) Adjust steering gear to tie rod boots at tie rod.
(6) Remove steering wheel clamp.
