CHECK THE CASTER Place the vehicle on an alignment rack.
● Is the caster within specification ?
→ YES
Go to G2.

a.Substitute a known good set of wheels and tires.
b. Perform a road test.
c. If the vehicle still exhibits a shake or vibration, note the vehicle speed
and/or engine rpm which it occurs.
● Is the vibration felt ?
→ YES
Engine/transmission imbalance.
See the specification of TR group, EM group, FL group and EC group.
→ NO
Install the original tire/wheel assemblies one by one, Road testing at
each step until the damaged tire(s)/wheel(s) as necessary. Test the
system for normal operation.
Wheel /tire noise, vibration and harshness concerns are directly related to vehicle speed and are not generally affected
by acceleration, coasting or decelerating. Also, out - of- balance wheel and tires can vibrate at more than one speed. A
vibration that is affected by the engine rpm, or is eliminated by placing the transmission in Neutral is not related to the
tire and wheel. As a general rule, tire and wheel vibrations felt in the steering wheel are related to the front tire and
wheel assemblies. Vibrations felt in the seat or floor are related to the rear tire and wheel assemblies. This can initially
isolate a concern to the front or rear.
Careful attention must be paid to the tire and wheels. There are several symptoms that can be caused by damaged or
worn tire and wheels. Perform a careful visual inspection of the tires and wheel assemblies. Spin the tires slowly and
watch for signs of lateral or radial runout. Refer to the tire wear chart to determine the tire wear conditions and actions WHEEL AND TIRE DIAGNOSIS

REMOVAL
1.Remove the connecting bolt (A) between the steering universal joint assembly (B) and the pinion assembly.
2.Loosen the wheel nuts slightly. Raise the front of the vehicle, and make sure it is securely supported.
3. Remove the front wheel and tire (A) from front hub (B).
Be careful not to damage the hub bolts (C) when removing the front wheel and tire (A).
4. Remove the front stabilizer link (A) nut (B) from the strut assembly.
5.After removing both sides of the tie rod end (A) self - locking nuts (B) and cotterpin (C), remove the ball joint by
using the special tool(09568- 4A000).

specification.
Tightening torque Nm (kgf.m, lb - ft) :
65 ~ 80 (6 ~ 8, 43.4 ~ 57.8)
9.Install the front stabilizer link (A) nut (B) to the strut assembly.
Tightening torque Nm (kgf.m, lb - ft) :
100 ~ 120 (10 ~ 12, 72.3 ~ 86.8)
10. Install the wheel and the tire (A) to the front hub (B).
Tightening torque Nm (kgf.m, lb - ft) :
90 ~ 110 (9 ~ 11, 65.1 ~ 79.5)
Be careful not to damage the hub bolts(C) when installing the front wheel and tire(A).
11. Install the connecting bolt (A) between the steering universal joint assembly (B) and the pinion assembly.

Tightening torque Nm (kgf.m, lb - ft) :
13 ~ 18 (1.3 ~ 1.8, 9.4 ~ 13.0)
After installation, if neccessary, adjust the alignment of the steering wheel and front tires
INSPECTION
1.Check the bushing for wear and deterioration.
2. Check the stabilizer bar for bending or breakage.
3. Check the ball joint for rotating torque.
(1) If there is a crack in the dust cover, replace it and add grease.
(2) Move the stabilizer link ball joint stud several times in a circular motion.
(3) Mount the self - locking nut on the ball joint, and then measure the ball joint rotating torque.
Standard value :
0.5 ~ 2.5 Nm (5 ~ 25 kgf., 0.36 ~ 1.81 lb - ft)
Measure torque using the special tool(09532- 11600) and torque wrench at the range of 0.5 - 2 rpm after
moving the ball joint stud 10 times at room temperature.
(4)If the rotating torque exceeds the upper limit of standard value, replace the upper arm assembly.
(5) Even if the rotating torque is below the lower limit of the standard value, the ball joint may be reused unless it
has drag and excessive play.

TIRE WEAR
1.Measure the tread depth of the tires.
Tread depth [limit] : 1.6 mm (0.063 in)
2. If the remaining tread(A) depth is less than the limit, replace the tire.
When the tread depth of the tires is less than 1.6 mm (0.063 in), the wear indicators(B) will appear.
TIRE ROTATION
Rotate the tires in the pattern illustrated.
CHECKING FOR PULL AND WANDER
If the steering pulls to one side, rotate the tires according to the following wheel rotation procedure.
1. Rotate the front right and front left tires, and perform a road test in order to confirm vehicle stability.

2.If the steering pulls to the opposite side, rotate the front and rear tires, and perform a road test again.
3.If the steering continues to pull to one side, rotate the front right and left tires again, and perform a road test.
4.If the steering continues to pull to the opposite side, replace the front wheels with new ones.

WHEEL ALIGNMENT
When using commercially available computerized four wheel alignment equipment (caster, camber, toe) to inspect the
front wheel alignment, always position the car on a level surface with the front wheels facing straight ahead.
Prior to inspection, make sure that the front suspension and steering system are in normal operating condition and
that the wheels and tires face straight ahead and the tires are inflated to the specified pressure.
TOE
Toe is a measurement of how much the front of the wheels are turned in or out from the straight- ahead position.
Item Description
A - B < 0 Positive (+) toe (toe in)
A - B > 0 Negative ( - ) toe (toe out)
When the wheels are turned in toward the front of the vehicle, toe is positive (+) (toe in). When the wheels are turned
out toward the front of the vehicle, toe is negative(- ) (toe out). Toe is measured in degrees, from side to side, and
totaled.
[FRONT]
Toe- in(B - A or angle a+b) is adjusted by turning the tie rod turnbuckles. Toe- in on the left front wheel can be reduced
by turning the tie rod toward the rear of the car. Toe- in change is adjusted by turning the tie rods for the right and left
heels simultaneously at the same amount as follows.
Standard value :
Toe- in (B- A) mm (in) : 0 ± 2 (0 ± 0.0787)
a. Toe- in adjustment should be made by turning the right and left tie rods at the same amount.
b. When adjusting toe - in, loosen the outer bellows clip to prevent twisting the bellows.
c. After the adjustment, tighten the tie rod end lock nuts firmly and reinstall the bellows clip.
d. Adjust each toe - in to be the range of ±1mm.
Tie rod(A) Specified torque Nm (kgf.m, lb - ft) :
70 ~ 80 (7 ~ 8, 50.6 ~ 57.8)

Noise Hissing Noise in Steering Gear
There is some noise with all power steering systems. One of the most common is a hissing
sound when the steering wheel is turned and the car is not moving. This noise will be most
evident when turning the wheel while the brakes are being applied. There is no relationship
between this noise and steering performance. Do not replace the valve unless the "hissing"
noise becomes extreme. A replaced valve will also make a slight noise, and is not always a
solution for the condition.
