When driving/moving a loud metallic clunking/clicking sound comes from the rear side brake hub on my car, be it forward or reverse it's a constant clunking. The sound originates from the hub area itself and not the diff. I've uploaded a video of the sound in action.

SOUNDS LIKE IT'S OUT ON THE END

WHEN YOUR LUG HITS THE 8 O'CLOCK POSITION IT CLICKS

MY 3 THOUGHTS

1) THE CV JOINT IS DOING IT

2) THE BRAKE PADS- REMOVE THE CALIPER AND SEE IF IT STOPS

3) THE ROTOR ONLY HAS ONE LUG IN IT, MAYBE IT IS NOT FULLY SEATED ON THE HUB OPPOSITE OF THAT LUG (THIS "WOBBLE" MIGHT ALSO MAKE THE BRAKE PADS MAKE A NOISE)/ INSTALL ALL OF THE LUGS TIGHT AND SEE IF IT STOPS (DO THIS BEFORE YOU REMOVE THE CALIPER!)
