Bucking on deceleration: when decelerating between 2000 rpm to 1500 the truck will start to buck. It seems very similar to a u-joint, but all three rear u joints have recently been replaced and are tight. Accelerating through the range it is not noticed and deceleration in any other RPM range it doesn't do it. The gear doesn't matter. Once it starts bucking I can begin to accelerate again and work it back out. The bucking immediately stops if the clutch is depressed. The speed does not matter, but it does seem less violent in higher gears. Any help on where to start looking.
The Engine was rebuilt approximately 3000 miles ago and has been doing it since then. It seems to be getting worse.
