occurs. 



Is the vibration felt?  

YES  

Engine/transmission imbalance. 

See AUTOMATIC TRANSAXLE SYSTEM , ENGINE MECHANICAL , FUEL DELIVERY 
SYSTEM and EMISSIONS CONTROL SYSTEM - GENERAL . 

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 Fig. 2 to determine the tire 
wear conditions and actions
