Bad Vibration I have a very bad vibration starting around 80MPH and up to 110MPH, I stopped there. As soon as I hit 80 at WOT the rear of my car started to shake really bad so I let off at about 110MPH. I slowed down to like 40-50 and the vibration went away. Hit it again and no vibration but I didn't bring it all the way back to 80MPH. Haven't had a chance to look at anything yet but what could be wrong, I am thinking either a U-joint, weight on the drive shaft, or possibly the rear. I am still running a stock 10 bolt, its an A4 with 3.23's. Is there anything in the rear that could make this vibration happen or is it something simpler?

no ideas, I looked at my driveshaft and u-joints and do not see anything wrong or any excessive slop. I would think if it was my diff or gears it would do it all the time.
