Clunk in the rear

[lesnyd@bb1t.monsanto.com (Larry E. Snyder - lesnyd@monsanto.com - (314)694-3626)]

When starting or shifting my TR250 I get a clunk from the rear end. I got under
and checked and the axles and drive shaft feel solid, no sign of play in the
U-joints. Because the clunk doesn't always seem to exactly coincide with
accelerating or decelerating, could it be one of the rubber suspension mounts?
Dare I drive this thing? Would a failing U-joint be easy to spot?

Thanks,

Larry
