Good point! Technically I guess I would have to say it happens on the downshift coming out of overdrive back into 4th gear as I accelerate or it starts up a hill. And this is the only time I hear it, it shifts out of park into drive and into reverse just fine with no noise whatsoever.
There seems to be minimal to no play in the drive shaft when I try to wiggle it, so I don't think it's a u-joint problem. Also, in response to the question about a rattle, it is definitely not that - it's more of a clunk/scrape sound that's hard to describe!
