MBkin, the sway bar links Dave mentions are indeed a simple fix, I just had mine done under warrnaty. The only thing is, when they fail, they don't produce squeeking, they produce the "loose suspension" noise when going over the speed bumps slowly. Otherwise, the performance is uneffected. I hear squeeking from my shocks when they compress, but I consider that normal hydraulic noise (it is not very loud, but if you nit-pick, it's squeeking).

Good luck
