STABILIZER BAR
DESCRIPTION
Some front-wheel-drive models use a stabilizer bar.
It 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.
OPERATION
Jounce and rebound movements affecting one
wheel are partially transmitted to the opposite wheel
to reduce body roll.

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.

RSWHEEL ALIGNMENT2-47
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
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.
