2nd generation Auroras are known to have some CV joint issues but not the Classics. CVs typically make noise while driving and turning and usually get louder or more pronounced if accelerating. (like a tight circle in a parking lot) As Zephram pointed out, don't let it go too long if this is your problem. A catastophic failure of a CV joint is nasty.

The strut bearing is at the top of the strut - if you open the hood and put your hand on the top of the strut tower while someone turns the steering you should be able to feel the noise in your hand.

Replace struts if thats the issue - however, the noise in mine is gradually going away as is someone's in another forum. if it just started then give it some time and maybe you'll get lucky too.
