Ok, so far no luck in finding the rattle. Weird thing is that rattle disappears when riding with my wife in the back. Can't explain it. If it is just me, I get the 30mph rattle. I hear it when I am decelerating and it hits the 30 mark briefly or if I drive at 30mph, it is a constant rattle. Just not if my wife is on the back.
