Go toD3.
→ NO
Adjust or Repair as necessary. Test the system for normal operation.
MEASURE THE LATERAL RUNOUT AND THE RADIAL RUNOUT OF THE FRONT WHEELS ON THE VEHICLE Measure the lateral runout and the radial runout of the front wheels on the
vehicle. Go to detailed test C.
● Are the measurements within specifications ?
→ YES
Go to D4.
→ NO
Install new wheels as necessary and Balance the assembly. Test the
system for normal operation.
MEASURE THE LATERAL RUNOUT OF THE FRONT TIRES ON THE VEHICLE Measure the lateral runout of the front tires on the vehicle. Go to detailed
test C.
● Is the runout within specifications ?
→ YES
Go to D5.
→ NO
Install new tires as necessary and Balance the assembly. Test the system
for normal operation.
MEASURE THE RADIAL RUNOUT OF THE FRONT TIRES ON THE VEHICLE Measure the radial runout of the front tires on the vehicle. Go to detailed
test C.
● Is the runout within specifications ?
→ YES
Balance the front wheel and tire assemblies. If any tire cannot be balanced,
Install a new tire. Test the system for normal operation.
→ NO
Go to D6.
MATCH MOUNT THE TIRE AND WHEEL ASSEMBLY Mark the high runout location on the tire and also on the wheel. Break the
assembly down and rotate the tire 180 degrees (halfway around) on the
wheel. Inflate the tire and measure the radial runout.
● Is the runout within specifications ?
→ YES
Balance the assembly. Test the system for normal operation.
→ NO
If the high spot is not within 101.6mm (4 inches) of the first high spot on
the tire, Go to D7.
MEASURE THE WHEEL FLANGE RUNOUT

● Is the vibration present ?
→ YES
Go to K2.
→ NO
The vehicle is OK. Go to TROUBLESHOOTING.
INSPECT THE TIRES
a.Raise and support the vehicle with a frame contact hoist.
b. Inspect the tires for extreme wear or damage, cupping, or flat spots.
● Are the tires OK ?
→ YES
Go to
→ NO
Check the suspension components for misalignment, abnormal wear, or
damage that may have contributed to the tire wear.
Correct the suspension concerns and Install new tires.
INSPECT THE WHEEL BEARINGS Spin the tires by hand to check for wheel bearing rougness.
● Is the front wheel bearing OK ?
→ YES
Go to K4.
→ NO
Install new front wheel bearings as necessary.
See Ds group - front axle.
TIRE/WHEEL BALANCE Check the tire/wheel balance.
● Are the tires balanced ?
→ YES
Go to K5.
→ NO
Balance the tires and wheels as necessary.
MEASURE THE RUNOUTS For each wheel position measure, locate and mark the following items.
- High point of the tire/wheel assembly total radial runout
- High point of the wheel radial runout
- High point of the wheel lateral runout
● Are the runouts as specified ?
→ YES
Go to K7.
→ NO
Go to K6.
SUBSTITUTE THE WHEELS AND TIRE

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
