The low E causes a rattle on the trem and if I take a finger and push on the piece the string is actually sitting on it goes away. I see a small hex bolt that holds that part on, is this whats wrong with it? Its also the only string that has some fret buzz when fretting and strumming the string anything other than light.

Since I am in GF1 here at GT its not that big of a deal and I am sure I will have to take it in but thats an hour away.
