I've had noises in the trunk of my 2007 for quite a while now. When I hit a rut in the road or a small pot hole a get this clunking noise. There is nothing in my trunk except the goop and the air compressor which is located where the spare tire should be. I did notice when I take out the carpeting to get to the spare location that the bolt which holds down the aircompressor seems to be hitting the wood on the bottom of the carpet. So I'm wondering if as I hit a hole or rut if that carpet with the wood which is attached to it, is jumping up and down and hitting that bolt causing the noise in the trunk. Does anyone else experience this problem and more importantly does anyone have any solutions for this problem.
