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 Fig. 2 to determine the tire
wear conditions and actions
