on my truck with the regular 10 bolt. you know how you got those 4 little gears in the case inside the chunk, i think it has 2 pinion gears and 2 side gears well the one at the top, center is shattered. i heard a pop last night so i took the cover off and found that gear, busted, laying in the botton of the housing. so how long can i drive it like that till i can fix it? it still pulls and everything.
