→ 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
Rapid wear at the center Rapid wear at both shoulders Wear at one shoulder
