Sadly, the rear diff problems came with the American Axle. I rebuilt many AA's in these trucks under warranty, but I don't recall doing any that would make a popping sound, just bearing howl. It saddens me hearing about more and more crooked dealerships nowadays. That line about diff maintenance and friction modifier is total b.s.
