Sounded to me like a noise/rattle that I once had. It was caused by some worn and partially incorrect exhaust hangers. Maybe try giving the tailpipes a good shaking, see if that makes any "clunks". If you take the car to get a 4 wheel alignment, I imagine the tech should be able to tell you if the tie-rod ends -"toes" are a problem.

My car had a rattle/bobble type noise in the back. It was the rear trailing arms or lateral links whatever they call them. They look like tie rods in the back. You won't be able to tell if they are loose with the rear wheels hanging down. If u can get under the car and shake them up and down real hard. They are real hard to tell because of the tension on em. But fixed my problem. I put Monroe shocks on the back too with new mounts and got rid of some of the noise but the lateral links fixed it all
