alright what is this noise? when i put my truck in reverse and back up , and then put it back in drive, about 50 feet or so driving forward there are big pops, and like the whole truck seens to jump, i really cant tell where it comes from becasue they r so big, i have a 700r4 which doesnt have much more life in it, im hopeing its that , but what else could it be, cuz it only does it after being in reverse, someone told me it could be my auto hubs , but i dont think thats what it is , does anyone what to take a guess?? thanks
