2003 Grand Am Squeaky noise

We purchased my car new about 2 years ago and haven't had any major problems with it. I wrecked it about 6 months ago and had to have everything (or at least I think they replaced everything) on the front passenger side replaced. Well after I got it fixed there was a noise and I had to have an axle replaced (which was supposed to be fixed after the accident). I got the car back after having a new axle put in it and I started hearing this really loud noise that sounds like a squeaky chair coming from the front passenger side. I take the car back they say they can't hear anything but they replace an intermediate shaft anyway (they also strip a screw while doing this). To make a long story short, my warranty has expired, all the times I took my car back to the dealer about the noise they never fixed it, and my car still has this noise. It also sounds as though there is something "loose" in the same area of the car when I go over bumps. The noise doesn't happen all the time, which makes me seem crazy sometimes when i'm trying to get someone to hear it. Any help would be much appreciated. Thanks!
