VIBRATION
Driveline Vibration
Tires that are out-of-round, or wheels that are not balanced, will cause a low frequency vibration.
Brake rotors that are unbalanced will cause a harsh, low frequency vibration.
Driveline vibration can also result from loose or damaged engine mounts.
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.
