i checked those.. this thing makes me sweat bullets.. its more of a thud or something comin from middle of truck it sounds.. maybe in rear.. from the outside sounds like something in the drums but from inside sounds like a thud

You ask us for opinions but then when we offer them you say no its not that it sounds like the drums. Well if it sounds like the drums then pull them aprat and inspect them.
