Ok so the little bolt that holds the main pin in the middle of the gears is broken. Part of the bolt comes out, the threaded part but I'm not sure if its all the threads or not n I would like to get it out! I would just drill it out but its in a tight spot. I don't want to replace the rearend again. Yes I swaped this one in their knowing it was busted but I had no choice at the time. The one I pulled out was much worse n not worth saving plus I only paid 40 bucks n I got the reared a crossmember made for duals wit new poly brushing n a crome diff cap.
