2B – 2 WHEEL ALIGNMENT
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
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 effort
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
D16A006A
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–degrees (0
) 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
D16A008A
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 to-
ward 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 de-
grees and is not adjustable.
CAMBER
D16A007A
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.
Camber is measured in degrees and is not adjustable.

FRONT TOE ADJUSTMENT
1. Separate the clamps from the both rack and pinion
boots.
2. Loosen the right and the left tie rod end lock nuts.
3. Turn the right and the left tie rod to align the toe.
In this adjustment, the right and left tie rods must be
equal in length.

4. Tighten the tie rod end lock nut to 45 Nm (33 lb-ft).
5. Install the rack and pinion boots clamp.
FRONT CAMBER AND CASTER
CHECK
The front camber and caster are not adjustable. Refer to
“Wheel Alignment Specifications” in this section. Jounce
the bumper three times before measuring the camber or
the caster in order to prevent an incorrect reading. If the
front camber or caster measurements deviate from the
specifications, locate and replace or repair any dam-
aged, loose, bent, dented, or worn suspension part. If
the problem is body related, repair the body.
REAR CAMBER CHECK
The rear camber is not adjustable. Refer to “Wheel
Alignment Specifications” in this section. If the rear cam-
ber deviates from the specification, locate the cause and
correct it. If damaged, loose, bent, dented, or worn sus-
pension parts are found, they should be repaired or re-
placed. If the problem is body related, repair the body.
REAR TOE CHECK
The rear toe is not adjustable. Refer to “Wheel Align-
ment Specifications” in this section. If the toe deviates
from the specification, check the rear axle assembly and
the wheel spindle on vehicles without an anti–lock brak-
ing system (ABS) or the rear axle assembly and the hub
and bearing assembly on vehicles with ABS for possible
damage.

DIAGNOSTIC INFORMATION AND PROCEDURES
STRUT DAMPENER
A strut dampener is basically a shock absorber. However, strut dampeners are easier to extend and retract by hand
than are shock absorbers. Strut dampeners are used only on the front in most vehicles, including this vehicle. Shock
absorbers are used on the rear wheels.
Condition Probable cause Correction
Struts Seem Weak
Improper tire pressures.
Adjust the tire pressures to the speci-
fications on the tire placard.

Abnormal load conditions.
Consult with the owner to confirm the
owner’s understanding of normal load
conditions.

Improper compression and rebound
effectiveness of the strut dampener.
Quickly push down and then lift up on
the corner of the bumper nearest the
strut dampener being tested.

Compare the compression and re-
bound with those of a similar vehicle
that has an acceptable ride quality.

Replace the strut dampener, if need-
ed.
Struts are Noisy
Loose or damaged mountings.
Tighten the strut dampener.

Replace the strut dampener if need-
ed.

Improper compression and rebound
effectiveness of the strut dampener.
Quickly push down and then lift up on
the corner of the bumper nearest the
strut dampener being tested.

Compare the compression and re-
bound with those of a similar vehicle
that has an acceptable ride quality.

Replace the strut dampener, if need-
ed.
Leaks
A slight trace of fluid.
The strut dampener is OK.

Leaks of the seal cover on the fully
extended strut.
Replace the strut dampener.

Excessive leaks of fluid on the strut
dampener.
Replace the strut dampener.
BALL JOINT AND KNUCKLE
Ball Joint Inspection
1. Raise the front of the vehicle to allow the front sus-
pension to hang free.
2. Grasp the tire at the top and the bottom.
3. Move the top of the tire in an in-and-out motion.
4. Look for any horizontal movement of the knuckle rela-
tive to the control arm.
5. Control arms assembly must be replaced if the follow-
ing conditions exist:

The joint is loose.

The ball seal is cut.

The ball stud is disconnected from the knuckle.
The ball stud is loose at the knuckle.

The ball stud can be twisted in its socket with finger
pressure.Ball Stud Inspection
Make sure to check the tightness of the ball stud in the
knuckle boss during each inspection of the ball joint.
One way to inspect the ball stud for wear is to shake the
wheel and feel for movement of the stud end or the cas-
tellated nut at the knuckle boss.
Another way to inspect the ball stud for wear is to check
the fastener torque at the castellated nut. A loose nut can
indicate a stressed stud or a hole in the knuckle boss.
Worn or damaged ball joints and knuckles must be re-
placed.
