PRE-ALIGNMENT VEHICLE INSPECTION
CAUTION: If the front suspension crossmember
shows any sign of impact damage, the steering col-
umn to steering gear coupling must be inspected.
Refer to Group 19 Steering in this service manual
for the inspection procedure.
Before any attempt is made to change or correct
the wheel alignment factors, the following inspection
and necessary corrections must be made on those
parts which influence the steering of the vehicle.
(1) Be sure the fuel tank is full when the wheel
alignment specifications are checked and or adjusted.
A full tank of fuel weighs approximately 75 pounds,
if the fuel tank is not full this reduction in weight
will affect the curb height of the vehicle and the
alignment specifications.
(2) Alignment specifications of a vehicle can be the
most accurately checked and set when the passenger
compartment and trunk of the vehicle are vacant
with the exception of the spare tire. People, luggage,
and any other appreciable weight will adversely
affect the checking and setting of the camber specifi-
cation.
(3) Check and if required, inflate all of the tires to
the recommended air pressure. All tires must be of
the same size and in good condition and have approx-
imately the same tread wear.Note the type of
tread wear on the tire, this will aid in diagnos-
ing problems. Refer to Group 22 Tires And
Wheels in this service manual for the tire wear
diagnosis.
(4) Check the front tire and wheel assemblies for
radial runout.
(5) Before beginning the alignment process,
inspect all suspension component fasteners for loose-
ness and/or loss of specified torque.
(6) Inspect the lower front ball joints and all steer-
ing linkage for looseness and any signs of wear and
or damage.
(7) Inspect the tie rod ends for looseness and any
signs of wear and or damage.
(8) Inspect the rubber bushings on all suspension
components for signs of wear or deterioration. If any
bushings show signs of wear or deterioration they
should be replaced prior to aligning the vehicle.
SERVICE PROCEDURES
WHEEL ALIGNMENT CHECK AND ADJUSTMENT
PROCEDURE
CASTER CAMBER
Front and rear Caster and Camber settings on this
vehicle are determined at the time the vehicle isdesigned, by the location of the vehicle's suspension
components. This is called a Net Build vehicle and
results in no required adjustment of Caster and
Camber after vehicle is built or when servicing the
suspension components. Thus Caster and Camber are
not normally considered an adjustable specification
when performing an alignment on this vehicle.
Though Caster and Camber are not adjustable they
must be checked to ensure they meet vehicle specifi-
cations.
If front and or rear camber is found not to meet
the vehicle alignment specifications, it can be
adjusted using a Mopar Service Kit developed to
allow for camber adjustment. If a vehicle's front or
rear camber is found to be outside the specifications,
the vehicles suspension components should be
inspected for any signs of damage on bending.This
must be done before using the Mopar Service
Kit for setting camber to meet required specifi-
cation.
If a vehicles caster is not within manufacturers
alignment specifications, check for damaged suspen-
sion components or body parts. This type of damage
can cause component locations to move affecting
vehicle alignment.No adjustment can be made
for the Caster setting on this vehicle.
CAUTION: Do not attempt to adjust the vehicles
Caster or Camber by heating, bending or any other
modification of the suspension components.
(1) Correctly position vehicle on alignment rack
and install all required equipment on vehicle, per the
alignment equipment manufacturers specifications.
(2) Center the steering wheel and lock in place
using a steering wheel clamp.
NOTE: Prior to reading each alignment specifica-
tion, jounce the front and rear of the vehicle 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.
(3) Correctly jounce vehicle and read front and
rear alignment settings and compare to vehicle spec-
ifications for Camber, Caster and Toe. See Alignment
Specifications in this group of the service manual for
required specifications.If front and rear camber
readings are within required specifications pro-
ceed to step Step 3 in the Front And Rear Toe
Setting procedure. If Camber readings are not
within specifications refer to step Step 1 in the
following camber adjustment bolt package
installation procedure, for the front and rear
Camber adjustment procedure.

DESCRIPTION AND OPERATION
TIRE INFORMATION
Tires are designed and engineered for each specific
vehicle. They provide the best overall performance
for normal operation. The ride and handling charac-
teristics match the vehicle's requirements. With
proper care they will give excellent reliability, trac-
tion, skid resistance, and tread life.
Driving habits have more effect on tire life than
any other factor. Careful drivers will obtain, in most
cases, much greater mileage than severe use or care-
less drivers. A few of the driving habits which will
shorten the life of any tire are:
²Rapid acceleration
²Severe application of brakes
²High-speed driving
²Taking turns at excessive speeds
²Striking curbs and other obstacles
²Operating vehicle with over or under inflated
tire pressures
Radial ply tires are more prone to irregular tread
wear. It is important to follow the tire rotation inter-
val shown in the section on Tire Rotation. This will
help to achieve a greater tread-life potential.
TIRE IDENTIFICATION
Tire type, size, aspect ratio and speed rating are
encoded in the letters and numbers imprinted on the
side wall of the tire. Refer to the chart to decipher
the tire identification code (Fig. 1).
Performance tires will have a speed rating letter
after the aspect ratio number. The speed rating is not
always printed on the tire sidewall. The letterSindi-
cates that the tire is speed rated up to 112 mph.
²Qup to 100 mph
²Tup to 118 mph
²Uup to 124 mph
²Hup to 130 mph
²Vup to 149 mph
²Zmore than 149 mph (consult the tire manu-
facturer for the specific speed rating)
An All Season type tire will have eitherM+S,M
&SorM-S(indicating mud and snow traction)
imprinted on the side wall.
TIRE CHAINS
Refer to the owners manual supplied with this
vehicle to determine whether the use of tire chains is
permitted on this vehicle.

RADIAL-PLY TIRES
Radial-ply tires improve handling, tread life and
ride quality, and decrease rolling resistance.
Radial-ply tires must always be used in sets of
four. Under no circumstances should they be used on
the front only. They may be mixed with temporary
spare tires when necessary. A maximum speed of 50
MPH is recommended while a temporary spare is in
use.
Radial-ply tires have the same load-carrying capac-
ity as other types of tires of the same size. They also
use the same recommended inflation pressures.
The use of oversized tires, either in the front or
rear of the vehicle, can cause vehicle drive train fail-
ure. This could also cause inaccurate wheel speed
signals when the vehicle is equipped with Anti-Lock
Brakes.
The use of tires from different manufactures on the
same vehicle is NOT recommended. The proper tire
pressure should be maintained on all four tires. For
proper tire pressure refer to the Tire Inflation Pres-
sure Chart provided with the vehicle.
SPARE TIRE±TEMPORARY
The temporary spare tire is designed for emer-
gency use only. The original tire should be repaired
or replaced at the first opportunity and reinstall. Donot exceed speeds of 50 MPH. Refer to Owner's Man-
ual for complete details.
TIRE INFLATION PRESSURES
Under inflation causes rapid shoulder wear, tire
flexing, and can result in tire failure (Fig. 2).
Over inflation causes rapid center wear and loss of
the tire's ability to cushion shocks (Fig. 3).
Improper inflation can cause:
²Uneven wear patterns
²Reduced tread life
²Reduced fuel economy
²Unsatisfactory ride
²The vehicle to drift.
For proper tire pressure specification refer to the
Tire Inflation Pressure Chart Placard provided with
the vehicle.
Tire pressures have been chosen to provide safe
operation, vehicle stability, and a smooth ride. Tire
pressure should be checked cold once per month.
Check tire pressure more frequently when the

DESCRIPTION AND OPERATION (Continued)

TIRE NOISE OR VIBRATION
Radial-ply tires are sensitive to force impulses
caused by improper mounting, vibration, wheel
defects, or possibly tire imbalance.
To find out if tires are causing the noise or vibra-
tion, drive the vehicle over a smooth road at varying
speeds. Note the noise level during acceleration and
deceleration. The engine, differential and exhaust
noises will change as speed varies, while the tire
noise will usually remain constant.
LEAD CORRECTION CHART
Use the following chart to diagnose a vehicle that
has a complaint of a drift or lead condition. The use
of the chart will help to determine if the lead condi-
tion is the result of a bad tire or is caused by the
front wheel alignment.
SERVICE PROCEDURES
TIRE AND WHEEL ROTATION
NON-DIRECTIONAL TREAD PATTERN TIRES
Tires on the front and rear axles operate at differ-
ent loads and perform different functions. For these
reasons, they wear at unequal rates, and tend to
develop irregular wear patterns. These effects can be
reduced by timely rotation of tires. The benefits of
rotation are especially worthwhile. Rotation will
increase tread life, help to maintain mud, snow, and
wet traction levels, and contribute to a smooth, quiet
ride.
The suggested rotation method is the forward-cross
tire rotation method (Fig. 6). This method takes
advantage of current tire industry practice whichallows rotation of radial-ply tires. Other rotation
methods may be used, but may not have all the ben-
efits of the recommended method.
NOTE: Only the 4 tire rotation method may be used
if the vehicle is equipped with a low mileage or tem-
porary spare tire.
DIRECTIONAL TREAD PATTERN TIRES
Some vehicles are fitted with special high-perfor-
mance tires having a directional tread pattern. These
tires are designed to improve traction on wet pave-
ment. To obtain the full benefits of this design, the
tires must be installed so that they rotate in the cor-
rect direction. This is indicated by arrows on the tire
sidewalls.
When wheels and tires are being installed, extra
care is needed to ensure that this direction of rota-
tion is maintained.
Refer to Owner's Manual for rotation schedule.
REPAIRING TIRE LEAKS
For proper repairing, a radial tire must be removed
from the wheel. Repairs should only be made if the
defect, or puncture, is in the tread area (Fig. 7). The
tire should be replaced if the puncture is located in
the sidewall.
Deflate tire completely before attempting to dis-
mount the tire from the wheel.Use a lubricant
such as a mild soap solution when dismounting
or mounting tire.Use tools free of burrs or sharp
edges which could damage the tire or wheel rim.
Before mounting tire on wheel, make sure all rust
is removed from the rim bead and repaint if neces-
sary.
