I sort of had the same problem, not sure if this will help you though. At highway speeds around 70 - 80 mph if I let off the throttle I got a nasty vibration coming through the whole car from the rear at first I thought it was a bad u-joint or maybe an unbalanced/bad driveshaft I almost ordered an aluminum driveshaft and new u-joints, although it would not have been a bad investment or mod it would not have solved my problem. I did my suspension recently and had to wait an extra day for my axle dampers to come in, I installed the shocks and struts the car was the same, but sure enough I installed the new axle dampers which I almost didnt even replace because I thought I did not need them and sure enough problem fixed. Like I said I am not sure if this is your problem but take a look at the dampers if they are old replace them the cost like $20 a piece.
