Vibration

Tires that are out-of-round, or wheels that are unbalanced, will cause a low frequency vibration. Refer to Steering and Suspension for additional information.
Brake drums that are unbalanced will cause a harsh, low frequency vibration. Refer to Brakes and Traction Control for additional information.
Driveline vibration can also result from loose or damaged engine mounts. Refer to Engine for additional information.
Propeller shaft vibration increases as the vehicle speed is increased. A vibration that occurs within a specific speed range is not usually caused by a propeller shaft being unbalanced. Defective universal joints, or an incorrect propeller shaft angle, are usually the cause of such a vibration.
