yup that was it i loosened the nut and i pulled it back didnt even need to hit with a hammer. thanx anitburn.
now the sub frame where the driveshaft passes through before the diff is rubbing the driveshaft. i think the previous owner bumped it just enough to bend it to do that so now im just going to grind it down alittle bit and should be fine. ill get some pics up soon.
