Listen, you and I can join the nuthouse together; maybe we can get some kind of group discount. I am not that mechanically inclined, but I do have a Bentley (the manual, not the car unfortunately), and so I was looking at the pictures of all the suspension components. I am a little hesitant to simply drop it off at my mechanic and say, "Fix this rattle!" He is very good and very honest, but I am concerned he might just pop in new shocks and struts and have it end up costing me more than I wanted to spend.

The car does not pull, drag, or vibrate at all, which makes me think that it must be a minor part. It does sound like there is some rubbing though, because if I am driving with the windows down and the radio off I can hear it. It sounds like something in the wheel though because it slows down and speeds up with the car. Probably something to do with the brakes, which might be unrelated. Thanks for all your help, guys. I'll definitely let you all know what it ended up being. I might brave my mechanic later this week. I might also pop into Click-And-Clack's (those NPR car talk guys) shop which is only several blocks from me. They are really nice and know what they are talking about.
