There is a fix. which I believe solves the problem better than TB's, spacers, or grease. I posted this a while back....our 2004 had loud rattles going over even small bumps.

"There was not a squeaking problem with ours, but more of clunking or rattling when going over bumps, even the slightest. I got in there and made the real fix......under the cover that has the hooks that latch down the top there is an adjustment for both sides. The large plastic cover pops off, and there are two arms with ball fitting with screw-in or out adjustments (first remove the wire spring clips, then snap the bracket off the ball). The issue is not that the top is not pulled down enough, it is. Watch the top as the top handle is operated to latch and un-latch the top. It is being pulled down. I found the problem is the hooks are not being pushed quite enough to prevent side to side movement (the pin fits into the very right angle of the hook). Make a slight adjustment so the the inside side of the hook is also snug against the pin, not just the horizontal surface. I made a one revolution on both sides (lengthening, not shortening the arm). Keep in mind slight, then try the operation, including trying to move the hook side to side after the adjustment (but try before any adjustments to see the play)."
