VIBRATION
Tires that are out-of-round, or wheels that are
unbalanced, 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 pro-
peller shaft being unbalanced. Defective joints or an
incorrect propeller shaft angle, are usually the cause
of such a vibration.
