It almost sounds like the RR strut, which is leaking magnetic fluid...I'll replace it later this loose at the top mount.

Going slowly in a parking lot, windows up, radio muted, I can hear a gentle thumping. Actually, it's more like a knock. Not a squeak, not a rattle, and once you're going over about 20 MPH, it gets so fast, you can't hear it any longer.
