I am pretty obsessive compulsive about rattles and even took the tray out at one stage but prefered the look with it in and so have gotten used to the noise. I took a look at the tray and figured that unfortunately it seems to have some inherent design flaws which promote rattles and think a one piece molded unit would have been more rigid & preferable. I am going to try out the idea in BeechSierra's posting to see if it helps - thanks for the ideas.
