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.

VEHICLE HEIGHT
Adjustment Procedure
1. Check the tire for proper inflation.
2. Measure ‘A’ from the center of the lower arm
rear mounting bolt end to the ground.
KAA2B050
3. Measure ‘B’ from the center of the steering
knuckle shaft to the ground.
KAA2B060
4. If the difference between ‘A’ and ‘B’ is not
within specification, adjust vehicle height using
torsion bar height control bolt.

FRONT TOE-IN ADJUSTMENT
Adjustment Procedure
1. Disconnect the outer tie rods from the knuckle as-
semblies. Refer to Section 6C, Power Steering
Gear.
2. Loosen the front toe adjusting nut.
Notice: In this adjustment, the right and the left tie
rods must be equal in length, or the tires will wear
unevenly.
3. Turn the right and the left outer tie rods to align the
toe to the proper specifications. Refer to “Wheel
Alignment Specifications” in this section.
KAA2B080
4. Hold the outer tie rod and tighten the front toe adjust-
ing nut.
Adjustment Notice
Tightening Torque 73 Nm (54 lb-ft)
5. Reconnect the outer tie rods to the knuckle assem-
blies. Refer to Section 6C, Power Steering Gear.

DIAGNOSTIC INFORMATION AND PROCEDURES
BALL JOINT INSPECTION
Ball Joint Inspection
1. Raise the front of the vehicle to allow the front
suspension 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
relative to the control arm.
5. Ball joints must be replaced under the following
conditions:
•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 at the
knuckle boss.
Another way to inspect the ball stud for wear is to check
the fastener torque at the pinch nut. A loose nut can
indicate a stressed stud orahole in theknuckle boss.
Worn of damaged ball joints and knuckles must be re-
placed.
