Rear diff chatter - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Got most of my truck debugged, but can't seem to be able to get the posi to stop chattering. I had originally put in Amsoil and added 2 of their posi additives but the chatter was still there. Today I dumped that out and replaced it with GL-5 petroleum based 80W-90 and a bottle of GM limited slip additive. Chatter is still there. It's especially noticeable after a long steady drive.
Any secrets to get this thing to quiet down?
