It really seems like some sort of spring is involved.

Hey Rob, my cowbells sounded exactly like your cowbell. And I too only heard it as I was creeping up to a stop, rolling out of the garage, etc. Actually, I recall that I had my lady stand next to the car as I went forward and back 1-2 feet in the garage so that she could isolate the noise for me (driver's rear wheel). So I heard it loud and clear just barely moving.

I don't know for certain what it was, but it definitely became dislodged and went away with some hard accelerations and stops. Worth a shot at least. Maybe you have a different issue, but like I said no distinction to be made between what I heard on your audio and what I experienced.
