well, my other problem is that i have a vibration in the car. I can rule out the tires, the wheels (crager) did take alot of weights. I was told that my driveshaft is about an inch to short. I was shimming the starter today and thought that maybe, along with the driveshaft, maybe my pinion angel is off. Will this cause a vibration? If so, what should the proper angle be?
