SHOCK ABSORBER
DESCRIPTION
There is one shock absorber on each side of the
rear suspension. The top of each shock absorber is
bolted to the frame rail. The bottom of each shock
absorber is bolted to the rear axle.
This vehicle is available with either standard type
or load-leveling shock absorbers. On the exterior,
load-leveling shock absorbers are larger in diameter
than standard shock absorbers. The load-leveling
shock absorbers mount the same as the standard
shock absorbers.
OPERATION
The shock absorber dampens jounce and rebound
motions of the spring and suspension.
Each load-leveling shock absorber is a self-leveling,
self-contained vehicle leveling system and shock
absorber combined. It does not require an external
compressor, hoses, or height leveling sensors. All the
height leveling sensors, hydraulic pump, etc., are
contained inside the shock absorber. It uses road
inputs (bumps, stops, starts, turns, acceleration,
deceleration, etc.) to activate pumping, which results
in the extension and compression of the shock
absorber.

STABILIZER BAR
DESCRIPTION
(1) Front-wheel-drive models use a stabilizer bar
that is mounted behind the rear axle. All-wheel-drive
models use a stabilizer bar that is mounted in front
of the rear axle.
The stabilizer bar interconnects both sides of the
rear axle and attaches to the rear frame rails using 2
rubber isolated link arms.
Both type stabilizer bars have the same basic com-
ponents. Attachment to the rear axle tube, and rear
frame rails is through rubber-isolated bushings.
The 2 rubber isolated links are connected to the
rear frame rails by brackets. These brackets are
bolted to the bottom of the frame rails.

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.

2 - 46 WHEEL ALIGNMENTRS

CASTER
Caster is the forward or rearward tilt of the steer-
ing knuckle in reference to the position of the upper
and lower ball joints. Caster is measured in degrees
of angle relative to a true vertical center line. This
line is viewed from the side of the tire and wheel
assembly (Fig. 2).
²Forward tilt (upper ball joint ahead of lower)
results in a negative caster angle.
²Rearward tilt (upper ball joint trailing lower)
results in a positive caster angle.
Although caster does not affect tire wear, a caster
imbalance between the two front wheels may cause
the vehicle to lead to the side with the least positive
caster.
CROSS CASTER
Cross caster is the difference between left and
right caster.
TOE
Toe is the inward or outward angle of the wheels
as viewed from above the vehicle (Fig. 3).
²Toe-in is produced when the front edges of the
wheels on the same axle are closer together than the
rear edges.
²Toe-out is produced when the front edges of the
wheels on the same axle are farther apart than the
rear edges.Toe-in and toe-out can occur at the front wheels
and the rear wheels.
Toe is measured in degrees or inches. The mea-
surement identifies the amount that the front of the
wheels point inward (toe-in) or outward (toe-out). Toe
is measured at the spindle height. Zero toe means
the front and rear edges of the wheels on the same
axle are equally distant.
TOE-OUT ON TURNS
Toe-out on turns is the relative positioning of the
front wheels while steering through a turn (Fig. 4).
This compensates for each front wheel's turning
radius. As the vehicle encounters a turn, the out-
board wheel must travel in a larger radius circle
than the inboard wheel. The steering system is
designed to make each wheel follow its particular
radius circle. To accomplish this, the front wheels
must progressively toe outward as the steering is
turned from center. This eliminates tire scrubbing

Fig. 3 Toe

2 - TOE-OUT
RSWHEEL ALIGNMENT2-47
WHEEL ALIGNMENT (Continued)

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.
