WHEEL ALIGNMENT
DESCRIPTION - WHEEL ALIGNMENT
Vehicle wheel alignment is the positioning of all
interrelated front and rear suspension angles. These
angles affect the handling and steering of the vehicle
when it is in motion. Proper wheel alignment is
essential for efficient steering, good directional stabil-
ity, and proper tire wear.
The method of checking a vehicle's front and rear
wheel alignment varies depending on the manufac-
turer and type of equipment used. The manufactur-
er's instructions should always be followed to ensure
accuracy of the alignment, except when
DaimlerChrysler Corporation's wheel alignment spec-
ifications differ.
On this vehicle, the suspension angles that can be
adjusted are as follows:
²Front Camber (with camber bolt package and
standard procedure)
²Front Toe
Check the wheel alignment and make all wheel
alignment adjustments with the vehicle standing at
its proper curb height specification. Curb height is
the normal riding height of the vehicle. It is mea-
sured from a certain point on the vehicle to the
ground or a designated area while the vehicle is sit-
ting on a flat, level surface. Refer to Curb Height
Measurement in this section for additional informa-
tion.
Typical wheel alignment angles and measurements
are described in the following paragraphs.
CAMBER
Camber is the inward or outward tilt of the top of
the tire and wheel assembly (Fig. 1). Camber is mea-
sured in degrees of angle relative to a true vertical
line. Camber is a tire wearing angle.
²Excessive negative camber will cause tread wear
at the inside of the tire.²Excessive positive camber will cause tread wear
on the outside of the tire.

STANDARD PROCEDURE
STANDARD PROCEDURE - WHEEL ALIGNMENT
PRE-WHEEL ALIGNMENT INSPECTION
Before any attempt is made to change or correct
the wheel alignment, the following inspection and
necessary corrections must be made to ensure proper
alignment.
(1) Verify that the fuel tank is full of fuel. If the
tank is not full, the reduction in weight will affect
the curb height of the vehicle and the alignment
angles.
(2) The passenger and luggage compartments of
the vehicle should be free of any load that is not fac-
tory equipment.
(3) Check the tires on the vehicle. All tires must be
the same size and in good condition with approxi-
mately the same amount of tread wear. Inflate all
the tires to the recommended air pressure.
(4) Check the front wheel and tire assemblies for
excessive radial runout.
(5) Inspect lower ball joints and all steering link-
age for looseness, binding, wear or damage. Repair as
necessary.(6) Check suspension fasteners for proper torque
and retighten as necessary.
(7) Inspect all suspension component rubber bush-
ings for signs of wear or deterioration. Replace any
faulty bushings or components before aligning the
vehicle.
(8) Check the vehicle's curb height to verify it is
within specifications. Refer to Curb Height Measure-
ment.
WHEEL ALIGNMENT SETUP
(1) Position the vehicle on an alignment rack.
(2) Install all required alignment equipment on
the vehicle per the alignment equipment manufactur-
er's instructions. On this vehicle, a four-wheel align-
ment is recommended.
NOTE: Prior to reading the vehicle's alignment
readouts, the front and rear of vehicle should be
jounced. Induce jounce (rear first, then front) by
grasping the center of the bumper and jouncing
each end of vehicle an equal number of times. The
bumper should always be released when vehicle is
at the bottom of the jounce cycle.
(3) Read the vehicle's current front and rear align-
ment settings. Compare the vehicle's current align-

CAUTION: Do not twist front inner tie rod to steer-
ing gear rubber boots during front wheel Toe
adjustment.
(2) Loosen front inner to outer tie rod end jam
nuts (Fig. 12). Grasp inner tie rods at serrations and
rotate inner tie rods of steering gear (Fig. 12) to set
front toe to the preferred toe specification. (Refer to 2
- SUSPENSION/WHEEL ALIGNMENT - SPECIFI-
CATIONS)
(3) Tighten tie rod jam nuts (Fig. 12) to 75 N´m
(55 ft. lbs.) torque.
(4) Adjust steering gear to tie rod boots at the
inner tie rod.
(5) Remove steering wheel clamp.
(6) Remove the alignment equipment.
(7) Road test the vehicle to verify the steering
wheel is straight and the vehicle does not wander or
pull.
STANDARD PROCEDURE - CURB HEIGHT
MEASUREMENT
The wheel alignment is to be checked and all align-
ment adjustments made with the vehicle at its
required curb height specification.
Vehicle height is to be checked with the vehicle on
a flat, level surface, preferably a vehicle alignmentrack. The tires are to be inflated to the recommended
pressure. All tires are to be the same size as stan-
dard equipment. Vehicle height is checked with the
fuel tank full of fuel, and no passenger or luggage
compartment load.
Vehicle height is not adjustable. If the measure-
ment is not within specifications, inspect the vehicle
for bent or weak suspension components. Compare
the parts tag on the suspect coil spring(s) to the
parts book and the vehicle sales code, checking for a
match. Once removed from the vehicle, compare the
coil spring height to a correct new or known good coil
spring. The heights should vary if the suspect spring
is weak.
(1) Measure from the inboard edge of the wheel
opening fender lip directly above the wheel center
(spindle), to the floor or alignment rack surface.
(2) When measuring, the maximum left-to-right
differential is not to exceed 12.5 mm (0.5 in.).
(3) Compare the measurements to the specifica-
tions listed in the following Curb Height Specifica-
tions charts.

SLIDING DOOR ADJUSTMENTS
NOTE: For power sliding door procedures refer to
POWER SLIDING DOOR SYSTEM in the ELECTRI-
CAL section.
PRELIMINARY CHECKS
(1) Close the sliding door, visually checking C-post
striker alignment entry into latch. Striker at this
point must not affect alignment. Striker should go
straight into the latching mechanism.
(2) On vehicles with left sliding doors, check the
fuel door blocker striker entry into latch. Striker at
this point must not affect alignment.
(3) Check C-post and B-post for door to aperture
gaps and door to door gaps. All gaps should be 5 mm
  1 mm.
(4) Check door for height using character lines as
a reference. Also check roof contour as a controlling
factor.
Using the procedures noted below, adjust the side
door in the order the individual steps are called out.
DOOR FLUSHNESS ADJUSTMENT
(1) Check sliding door flushness at the C-pillar
striker.
(2) Adjust the C-pillar striker in or out until the
door is flush.
(3) Check upper B-pillar flushness to A-pillar
cover.
(4) Loosen one nut on upper hinge and adjust door
in or out until the door is flush.
(5) Check flushness at upper C-pillar.
(6) If upper C-pillar flushness is out of specifica-
tion use a heavy rubber mallet on the door assembly
until door is in specifications.
DOOR GAP ADJUSTMENT - UP/DOWN
(1) Visually inspect the sliding door for fitting low
at the top of the door by checking the alignment of
the top contour of the door to the quarter panel.
