I have had this problem for about 3-4 years now. Whenever I accelerate from about 50-80mph I get a nasty shaking through the steering wheel, floor, everywhere; and passangers can feel it as bad as I do. I have new engine mounts, and have replaced the CV joints 2 times now. When I change the right CV out the shaking is noticably lessened, but it is definatly still there. What can I do, I am at a loss and everyone I have talked to has no clue either. I need to fix this, the ammount of shaking that goes on can not be good for the rest of the car... Thanks for the help!! -Nick
