operation.
→ NO
Go toB4.
CHECK THE TRAILING ARMS
a.Inspect the trailing arm bushings for wear or damage. Check for loose
trailing arm bolts.
b. Inspect for twisted or bent trailing arms.
● Are the trailing arms loose, damaged or worn ?
→ YES
Repair or Install new components as necessary. Test the system for
normal operation.
→ NO
Suspension system is OK. Conduct diagnosis on other suspect systems.
DETAILED TEST C : WHEEL AND TIRE CONDITIONS DETAILS/RESULTS/ACTIONS
ROAD TEST THE VEHICLE
Wheel or tire vibrations felt in the steering wheel are most likely related
to the front wheel or tire. Vibration felt through the seat are most likely
related to the rear wheel or tire. This may not always be true, but it can
help to isolate the problem to the front or rear of the vehicle.
Test drive the vehicle at different speed ranges.
During the road test, if the vibration can be eliminated by placing the
vehicle in neutral or is affected by the speed of the engine, the cause is not
the wheels or tires.
● Is there a vibration and noise ?
→ YES
Go to C2.
→ NO
The wheel and tires are OK. Conduct a diagnosis on other suspect
systems.
CHECK THE FRONT WHEEL BEARINGS Check the front wheel bearings.
Refer to Wheel Bearing Check (See DS group - front axle).
● Are the wheel bearings OK ?
→ YES
Go to C3.
→ NO
Inspect the wheel bearings. Adjust or Repair as necessary. Test the system
for normal operation.
INSPECT THE TIRES
a.Check the tires for missing weights.
b. Check the wheels for damage.

Dismount the tire and mount the wheel on a wheel balancer. Measure the
runout on both wheel flanges. Go to detailed test C
● Is the runout within specifications ?
→ YES
Locate and Mark the low spot on the wheel. Install the tire, matching the
high spot on the tire with the low spot on the wheel. Balance the assembly.
Test the system for normal operation. If the condition persists, Go to D8.
→ NO
Install a new wheel. Check the runout on the new wheel. If the new wheel
is within limits, locate and Mark the low spot. Install the tire, matching the
high spot on the tire with the low spot on the wheel. Balance the assembly.
Test the system for normal operation. If the condition persists, Go to D8.
CHECK FOR VIBRATION FROM THE FRONT OF THE VEHICLE Spin the front wheel and tire assemblies with a wheel balancer while the
vehicle is raised on a hoist. Feel for vibration in the front fender or while
seated in the vehicle.
● Is the vibration present ?
→ YES
Substitute known good wheel and tire assemblies as necessary.
Test the system for normal operation.
→ NO
Check the driveline components. Test the system for normal operation.
DETAILED TEST E : DRIFT LEFT OR RIGHT CONDITIONS DETAILS/RESULTS/ACTIONS

Install new tires.
→ NO
Go to E2.
CHECK THE STEERING LINKAGE
a.Raise and support the vehicle.
b. Check the steering components for indications of excessive wear or
damage.
See ST group - specification.
● Is there an indication of excessive wear or damage ?
→ YES
Repair or Install new components as necessary.
→ NO
Go to
CHECK THE VEHICLE ALIGNMENT a.Place the vehicle on an alignment rack.

Check the vehicle alignmnt.
● Is the alignment within specification ?
→ YES
Go to
→ NO
Adjust the alignment as necessary.
See page SS - 69 (wheel alignment).
BRAKE DRAG DIAGNOSIS Apply the brakes while driving.
● Does drift or pull occur when the brakes are applied ?
→ YES
See BR group - specification.
→ NO
If the steering wheel is in the center, the vehicle is OK.
If the steering wheel is off- center, Go to Detailed Test F.
DETAILED TEST F : STEERING WHEEL OFF- CENTER CONDITIONS DETAILS/RESULTS/ACTIONS
CHECK THE CLEAR VISION Place the vehicle on an alignment rack.
● Is the clear vision within specification ?
→ YES
Go to F2.
→ NO
Adjust the clear vision to specification.
INSPECT THE STEERING COMPONENTS
a.Raise and support the vehicle.
b. Inspect the steering components for excessive wear or damage.
See ST group - specification.
● Are the steering components excessively worn or damaged ?
→ YES
Repair or Install new components as necessary.
→ NO
If it tracks correctly, vehicle is OK.
If it tracks incorrectly, Go to Detailed Test
DETAILED TEST G : TRACKS INCORRECTLY CONDITIONS DETAILS/RESULTS/ACTIONS
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

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.
