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.
Page 496 of 1575

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.

→ YES
Repair or Install new components as necessary.
→ NO
Go to
CHECK THE VEHICLE ALIGNMENT a.Place the vehicle on an alignment rack.

→ 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.

Page 501 of 1575

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

excessive over inflated tires
