I read a few days ago (before the server crash) that some people with 05's were experiencing a metallic shaking from the underbody and that two bolts were missing from something (I can't remember what they said it was). I would like to hear from the people that had this problem because I am experiencing the same thing. We had one of our first nice days here in PA and got to drive with the windows down when I heard it. Please let me know what the problem is so I can get Ford service to fix it. Thanks.
