When I'm accelerating, the steering wheel does not vibrate much. When I am cruising with light throttle to keep speed it also does not vibrate much. As soon as I decelerate, all hell breaks loose and it feels like my arms are going to be ripped out of the sockets. I'm thinking either axle(s) or wheel(s). I am going to swap the front tires to the back to see if i can eliminate the problem. Any other advice. I just got the car aligned today and it used to vibrate a lil, now it's hellacious!
