Can't hear it over a computer. I can think of a lot of things that go "clunk", but if it only does it when you start to move, and it's repetitive, I'd start by inspecting the universal joints. If it's a single clunk, look at the rear transmission mount.
There is a tool you might be able to borrow or rent from an auto parts store that borrows them called the "Chassis Ear". It is a set of six microphones, a switch box, and headphones. You clip the microphones to suspect points, then drive around while listening with the headphones. You can move the microphones around to zero in on the source of the noise. Be aware that many mechanics have never seen or even heard of this tool. Suspension and alignment mechanics use it to find rattles, squeaks, and other noises.
