Tom;
As others have mentioned, a worn Driveshaft Center Support, which allows excessive movement will cause this. Earlier (two donut) version, especially when outfitted with the whimpier replacement donuts are more susceptible to this. To check, grab Driveshaft and give it a healthy tug in various directions...it is undesirable for it to audibly hit anything solid with a clunk, the forces applied when drivetrain is loaded are even more substantial.
