my wife noticed a vibration coming from the rear end of the truck when its decelerating and coasting at low speeds (under 35 mph), just put new tires on but dont think thats the problem as its not a constant shake, im not in the us to diagnose the problem my self but its only a shake from the rear and no whine or squeal like if you pinion comes out of spacing or a u joint goes bad truck has roughly 30,000 miles on it, any ideas would help so i dont come home to a major problem that involves shop work from Afghanistan

Do you have a manual. If so does it do it when you let it idle and roll in first gear. Mine has a vibration kinda sound when I do it. It has since new. Figured it was normal.

don't know if this helps but mine was doing a similar deal and my shop put shims where the driveshaft split it and now is gone at normal take off but if you punch it you can still feel it. Not sure exactly what they did though.
