Symptom Chart - Vehicle-Speed Related Vibrations
WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Any assembly that is out of balance will only cause a first order vibration, it will not cause a higher order vibration.
When a vehicle-speed related vibration is present, both tire-speed related vibration and driveshaft-speed related vibration calculations should be carried out.
