Accelerate the vehicle to the speed at which the customer indicated the vibration occured.
●
Is the vibration present ?
⇒
YES
Go to K2.
⇒
NO

Go to K3.
⇒
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.
K3 INSPECT THE WHEEL BEARINGS
Spin the tires by hand to check for wheel bearing rougness.
●
Is the front wheel bearing OK ?

- High point of the wheel radial runout
- High point of the wheel lateral runout
●
Are the runouts as specified ?
⇒
YES
Go to K7.
⇒
NO

GENERAL
SS -25
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
