Re: Vibration at 70-80 mph?? Frustrated
If you think it is a wheel/tire balance problem, try to get the tires statically balanced on the wheel first, then do an on car dynamic balance. That will take the entire wheel assembly into consideration. If there is another lister nearby, maybe you could swap your wheels and tires with his/hers, and then either eliminate or pinpoint the wheel tire combo as your problem. The fact that you have front and rear vibration would seem to indicate wheels and/or tires.
