hello, im a new memeber here... let me jump right into my problem... i have a 1999 A8, great car very powerful and smooth... just a few weeks ago when ever i go over bumps the passanger side front wheel well has been making a almost metal rubbing noise and now it has gotten worse to the point where even when i go over the slightest bump it makes the loudest rubbing noise... any ideas could it be the shocks and struts? Thanks!
