Troubleshooting

TROUBLESHOOTING

• Do not spill brake fluid, engine oil or transmission fluid on the vehicle. If contact occurs, wash the affected part immediately with water.

Noise, vibration and squeal from the wheel/tire are directly related to vehicle speed and usually do not depend on acceleration or deceleration. Unbalanced wheels and tires may vibrate at high speeds. Vibration related to engine speed, or that can be eliminated by shifting the transmission to neutral, is not related to the tire and wheel. In principle, wheel and tire vibrations felt in the steering wheel are related to the tire and front wheel assembly. Vibrations felt in the seat or floor are related to the rear wheel and tire assembly. This isolates the problem to the front or rear. Tires and wheels must be carefully inspected. Several symptoms may be caused by damaged tires or wheels. Perform a visual inspection of the tire and wheel assembly. Rotate the tires slowly and inspect them for signs of side wear or radial wear. Refer to the tire wear table to determine tire wear conditions and required actions.

WHEEL AND TIRE DIAGNOSIS
Rapid Wear in Center Area	Rapid Wear on Both Shoulders	Wear on One Side
Center Tread Wear Due to Overinflation No Rotation Excessive Toe-in on Drive Wheels Excessive Acceleration While Driving	Underinflation Worn Suspension Components Excessive Speed in Turns No Rotation	Toe Adjustment Not to Specification Camber Out of Specification Damaged Tread Damaged Lower Arm
Partial Wear	Burred Edge	Wear Type
Caused by uneven burrs on brake drums.	Toe Adjustment Not to Specification Damaged or Worn Tie Rod Ends Damaged Rim	Excessive Toe-In of Non-Driven Wheels No Rotation
