2B-2 WHEEL ALIGNMENT
FOUR WHEEL ALIGNMENT
The first responsibility of engineering is to design safe
steering and suspension systems. Each component
must be strong enough to withstand and absorb extreme
punishment. Both the steering system and the front
and the rear suspension must function geometrically
with the body mass.
The steering and the suspension systems require that
the front wheels self-return and that the tire rolling effor t
and the road friction be held to a negligible force in
order to allow the customer to direct the vehicle with
the least effort and the most comfort.
A complete wheel alignment check should include mea-
surements of the rear toe and camber.
Four-wheel alignment assures that all four wheels will
be running in precisely the same direction.
When the vehicle is geometrically aligned, fuel economy
and tire life are at their peak, and steering and perfor
mance are maximized.
TOE-IN
Toe-in is the turning in of the tires, while toe-out is the
turning out of the tires from the geometric centerline or
thrust line. The toe ensures parallel rolling of the wheels.
The toe serves to offset the small deflections of the
wheel support system which occur when the vehicle is
rolling forward. The specified toe angle is the setting
which achieves 0 degrees of toe when the vehicle is
moving.
Incorrect toe-in or toe-out will cause tire wear and re
duced fuel economy. As the individual steering and
sus-pension components wear from vehicle mileage,
additional toe will be needed to compensate for the
wear.
Always correct the toe dimension last.
CASTER
Caster is the tilting of the uppermost point of the steering
axis either forward or backward from the vertical when
viewed from the side of the vehicle. A backward tilt is
positive, and a forward tilt is negative. Caster influences
directional control of the steering but does not affect
tire wear. Weak springs or overloading a vehicle will
affect caster. One wheel with more positive caster will
pull toward the center of the car. This condition will
cause the car to move or lean toward the side with the
least amount of positive caster. Caster is measured in
degrees.
CAMBER
Camber is the tilting of the top of the tire from the
vertical when viewed from the front of the vehicle. When
the tires tilt outward, the camber is positive. When the
tires tilt inward, the camber is negative. The camber
angle is measured in degrees from the vertical. Camber
in-fluences both directional control and tire wear.
If the vehicle has too much positive camber, the outside
shoulder of the tire will wear. If the vehicle has too
much negative camber, the inside shoulder of the tire
will wear.

DIAGNOSTIC INFORMATION AND PROCEDURES
TIRE DIAGNOSIS
Irregular and Premature Wear
Irregular and premature tire wear has many causes.
Some of them are incorrect inflation pressures, lack of
regular rotation, poor driving habits, or improper wheel
alignment.
Rotate the tires if :
•The front tire wear is different from the rear.
The left and right front tire wear is unequal.
The left and right rear tire wear is unequal.
Check wheel alignment if :
The left and right front tire wear is unequal.
The wear is uneven across the tread of either front
tire.
The front tire treads are scuffed with “feather” edges
on the side of the tread ribs or blocks.
Tread Wear Indicators
The original equipment tires have built-in tread wear in
dicators to show when the tires need replacement.
These indicators appear as bands when the tire tread
depth becomes shallow. Tire replacement is recom
mended when the indicators appear in three or more
grooves at six locations.
KAA2B010
Radial Tire Waddle
Waddle is side-to-side movement at the front or rear of
the vehicle. It is caused by the steel belt not being
straight within the tire, or by excessive lateral runout
of the tire or wheel.
The vehicle must be road tested to determine which
end of the vehicle has the faulty tire. The rear end of
the vehicle will shake from side to side or “waddle” if
the waddle tire is on the rear of the vehicle. From the
driver’s seat, it feels as though someone is pushing
on the side of the vehicle.
If the faulty tire is on the front of the vehicle, the waddle
is more visual. The front sheet meld appears to be mov-
ing back and forth, and the drivers seat feels like the
pivot point in the vehicle.
Waddle can be diagnosed using the method of substitut-
ing known good tire and wheel assemblies on the prob-
lem vehicle.
1. Road test the vehicle to determine if the waddle is
coming from the front or the rear of the vehicle.
2. Install good tires and wheels from a similar vehicle
in place of those on the offending end of the problem
vehicle. If the source of the waddle is not obvious,
change the rear tires.
3. Road test the vehicle. If there is improvement,
install the original tires to find the offending tire. If
there is no a straight improvement, install good tires
in place of all four offending tires.

RADIAL TIRE LEAD/PULL
Lead/pull is the deviation of the vehicle from a straight
path on a level road with no pressure on the steering
wheel. Lead is usually caused by:
Incorrect alignment.
Uneven brake adjustment.
Tire construction.
The way in which a tire is built can produce lead/pull in
the vehicle. Off-center belts on radial tires can cause
the tire to develop a side force while the vehicle rolls
straight down the road. If one side of the tire has even
a little larger diameter than the diameter of the other
side, the tire will tend to roll to one side. Unequal
diameters will cause the tire to develop a side force
which can produce vehicle lead/pull.
The radial lead/pull diagnosis chart should be used to
determine whether the problem originates from an align-
ment problem or from the tires. Part of the lead diagno-
sis procedure calls for tire rotation that is different from
the proper tire rotation pattern. If a medium-to high-
mileage tire is moved to the other side of the vehicle,
be sure to check for ride roughness. Rear tires will not
cause lead/pull.

2B-6 WHEEL ALIGNMENT
VIBRATION DIAGNOSIS
Wheel imbalance causes most highway speed vibration
problems. A vibration can remain after dynamic balanc-
ing because:
A tire is out of round
A rim is out of round
A tire stiffness variation exists
Measuring tire and wheel free runout will uncover only
part of the problem. All three causes, known as loaded
radial runout, must be checked using method of substi-
tuting known good tire and wheel assemblies on the
problem vehicle.
Tire Balancing
Balance is the easiest procedure to perform and should
be done first if the vibration occurs at high speeds. Do
an off-vehicle, two-plane dynamic balance first to
correct any imbalance in the tire and wheel assembly.
An on-vehicle finish balance will correct any brake drum,
rotor, or wheel cover imbalance, If balancing does not
correct the high-speed vibration, or if the vibration oc-
curs at low speeds, runout is the probable cause.
Preliminary Checks
Prior to performing any work, always road test the car
and perform a careful visual inspection for:
Obvious tire and wheel runout.
Obvious drive axle runout.
Improper tire inflation.
Incorrect trim height.
Bent or damaged wheels.
Debris build-up on the tire or the wheel.
Irregular or excessive tire wear.
Improper tire bead seating on the rim,
Imperfections in the tires, including: tread deforma-
tions, separations, or bulges from impact damage.
Slight sidewall indentations are normal and will not
affect ride quality.
