After realigning the forgings to be parallel, I have zero noise and everything's copacetic even over sharp and big bumps. Just make sure they're parallel and you'll have no issues!
On another note, traction is WORLDS better. Just a bit of slip and she goes. This makes me feel better as I can now put that $2K+ I allocated for a rear diff into something else like my 401K or a starter deposit on an RS3
