Today the wife's truck (2004 F-250 ECSB 4X4) started making a snapping sound from the rear end, only noticeable under 20 mph. Doesn't matter if you are going straight or turning, still the same sound, and it doesn't do it every time either. When you grab the tire, (either side, both with same results) and shake it there is a a clunking noise that I assume translates into the snapping you hear when moving. Rear end is full of fluid. Any idea's what it might be?
