Vibration
Heres the deal. When i get up to speed ( about 90mph) my car shakes really bad. Last time this happened rear seal from tranny fell out. Which shook even worse. Ive had new drive shaft made, new ujoints ect. Ive jacked the car up and ran it to 130mph with no shakes at all? Its got me baffeled to say the least. Could it be a bent rim? By the way its a 65 skylark 383 stroker, 4 link prostreet. Thanks
