That was what my next question was going to be! haha I've had that happen to me before but with a set of known good wheels. what had happened was the top caliper bolt had vibrated out so when the car was moving forward, everything was fine. But when the car went in reverse, the caliper would roll off the rotor and I'd hear a loud clunking. Took a minute to figure out what hte heck was going on because when I'd rotate the wheel in reverse by hand, it would push the caliper off! lol Finally I had my wife back the car up while i watched and it was obvious. Just glad it was the top bolt and not the bottom or that wheel might have bound up and sent me for a ride! haha

Glad you figured it out.
