2.7t A6 Quattro identify issue
 

My car hit a curb last month during freak nasty snow storm.
Got it towed back and had some time to take a look at today. Put it up on ramps. I spent hours under it trying to see where the damage was. Can not pinpoint an exact spot/part. Took the tire off. Seems to spin ok so don't think it's a problem with the hub/bearings. Thought someone on here might have some suggestions.
I fishtailed out, spun around and hit the rear drivers tire pretty hard on the curb.
Car is a 2003 A6 2.7t 6 speed. I'm stumped. Any ideas ?
