Symptom Chart - Vehicle-Speed Related Vibrations
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. 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.
