I JUST RESOLVED MY RATTLING PROB. AFTER YOU CLOSE THE HATCH, PUSH DOWN HEAVILLY ON EACH SIDE SEPERATELY AT THE VERY END OF THE HATCH. IF THERE IS EVEN TWO MILLIMETERS OF PLAY IT WILL RATTLE LIKE CRAZY WHEN YOU DRIVE. ADJUST THE RUBBER STOPS ON EITHER SIDE SO THAT IT IS A VERY SNUG FIT WHEN CLOSED (NO PLAY AT ALL).

HOPE IT WORKS. LET US KNOW.
