I have a mild annoying vibration between 70 and 80-85. When i let off the gas the vibration gets a little worse and the smooths out to glass below 70. I have had tires balanced repeatedly as well as rotated. No Luck. took it to a shop who said it was not u-joints but may be bearings in the rear diff wobbling at high speeds. Anyone Have any ideas or solutions?

 

I moved this thread to the correct section.
