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.CROSS CAMBER
Cross camber is the difference between left and
right camber. To achieve the cross camber reading,
subtract the right side camber reading from the left.
For example, if the left camber is +0.3É and the right
camber is 0.0É, the cross camber would be +0.3É.

a turn.
DYNAMIC TOE PATTERN
Dynamic toe pattern is the inward and outward toe
movement of the front and rear tires through the
suspensions jounce a

and undue tire wear when steering a vehicle through
a turn.
DYNAMIC TOE PATTERN
Dynamic toe pattern is the inward and outward toe
movement of the front and rear tires through the
suspension's jounce and rebound travel. As the vehi-
cle's suspension moves up and down, the toe pattern
varies. Toe pattern is critical in controlling the direc-
tional stability of the vehicle while in motion. Front
and rear dynamic toe pattern is preset by the factory
at the time the vehicle is assembled.
It is not necessary to check or adjust front or rear
dynamic toe pattern when doing a normal wheel
alignment. The only time dynamic toe pattern needs
to be checked or adjusted is if the frame of the vehi-
cle has been damaged.
STEERING AXIS INCLINATION (S. A. I.)
Steering axis inclination is the angle between a
true vertical line starting at the center of the tire at
the road contact point and a line drawn through the
center of the upper ball joint (or strut) and the lower
ball joint (Fig. 5). S.A.I. is built into the vehicle and
is not an adjustable angle. If S.A.I. is not within
specifications, a bent or damaged suspension compo-
nent may be the cause.
INCLUDED ANGLE (I. A.)
Included angle is the sum of the S.A.I. angle plus
or minus the camber angle, depending on whether or
not the wheel has positive or negative camber (Fig.
5). If camber is positive, add the camber angle to the
S.A.I. angle. If camber is negative, subtract the cam-
ber angle from the S.A.I. angle. Included angle is not
adjustable, but can be used to diagnose a frame mis-
alignment or bent suspension component (spindle,
strut).
THRUST ANGLE
Thrust angle is the averaged direction the rear
wheels are pointing in relation to the vehicle's center
line (Fig. 6). The presence of negative or positive
thrust angle causes the rear tires to track improperly
to the left or right of the front tires (dog tracking).
²Negative thrust angle means the rear tires are
tracking to the left of the front tires.
²Positive thrust angle means the rear tires are
tracking to the right of the front tires.
Improper tracking can cause undue tire wear, a
lead or pull and a crooked steering wheel. Excessive
thrust angle can usually be corrected by adjusting
the rear wheel toe so that each wheel has one-half of
the total toe measurement.

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-
ment settings to the vehicle specifications for camber,
caster and toe-in. (Refer to 2 - SUSPENSION/
WHEEL ALIGNMENT - SPECIFICATIONS)
(4) If front camber and caster are not within spec-
ifications, proceed to CAMBER AND CASTER below.
If caster and camber are within specifications, pro-
ceed to TOE which can be found following CAMBER
AND CASTER. Rear camber, caster and toe are not
adjustable. If found not to be within specifications,
reinspect for damaged suspension or body compo-
nents and replace as necessary.
CAMBER AND CASTER
Camber and caster settings on this vehicle are
determined at the time the vehicle is designed, by
the location of the vehicle's suspension components.
This is referred to as NET BUILD. The result is no

required adjustment of camber and caster after the
vehicle is built or when servicing the suspension
components. Thus, when performing a wheel align-
ment, caster and camber are not normally considered
adjustable angles. Camber and caster should be
checked to ensure they meet vehicle specifications.
If front camber is found not to meet alignment
specifications, it can be adjusted using an available
camber adjustment bolt package. Before installing a
camber adjustment bolt package on a vehicle found
to be outside the specifications, inspect the suspen-
sion components for any signs of damage or bending.
CAUTION: Do not attempt to adjust the vehicles
wheel; alignment by heating, bending or by per-
forming any other modification to the vehicle's front
suspension components or body.
If camber readings are not within specifications,
use the following procedure to install the front cam-
ber adjustment bolt package and then adjust front
camber.
CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION
The camber adjustment bolt package contains 2
flange bolts, 2 cam bolts, 2 dog bone washers, and 4
nuts. This package services both sides of the vehicle.
Use the package to attach the strut clevis bracket to
the steering knuckle after the strut clevis bracket
has been modified. To install and adjust the camber
adjustment bolt package, follow the procedure below.
(1) Raise the vehicle until its tires are not support-
ing the weight of the vehicle.
(2) Remove the front tire and wheel assemblies.
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 knuckle to strut assembly attaching
bolt shanks are serrated and must not be turned
during removal. Remove the nuts while holding the
bolts stationary.
(3) Remove the top and bottom, strut clevis
bracket to steering knuckle attaching bolts (Fig.
7)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 on the sides of the strut
clevis bracket (Fig. 8).
(4) Using an appropriate grinder and grinding
wheel, slot the bottom hole in both sides of the strut
clevis bracket (Fig. 8).
