Default Noise in Drive Train

I just got back from a 300 mile tour with a number of Model A friends, and I noticed a noise in the drive train about halfway through the trip. I initially thought I wasnít pressing on the clutch far enough, but it turns out that the clutch does not affect the noise at all.

Itís a thump thump thump sound, and it does not seem to appear as long as I have a load on the drive train. However, when I let off the gas, I sometimes hear the thump thump thump sound, especially at low speeds, around 5-10 mph.

I was in a parking lot near home, and I especially heard it while coasting in neutral.

Iím thinking this is either the universal joint or something in the differential.

Can anyone offer any debug advice?
