Well I just started to pull it apart some. I pulled to two rear wheels and pulled to pin/bolt so that I could drop the bearings/housings down and pull the two drive shafts out of the differential. I feel fairly confident that I have found the problem haha. I've added a couple pics of the damage.

I am really surprised that this broke like this, for one, so soon and two, under such a relatively easy driving...at least compared to what I read about people on here doing with them! I really hope they don't all break this easy. I was just getting it tuned up good and getting on it for maybe 10 min at most before it broke!

What is the best way to go about removing the diff? I'm assuming I have to take the whole rear end section of the truck off and tear it down?

Thanks
