Changed the diff oil in all of my diffs (500k center, 100k front, 60k rear) took it out for one run and it ran awsome. took it out today and 10 mins in it started smoking and stopped moving. Pop open the cover to find black diff fluid all over and see a hole in the center diff case. What could have happened?

Sure did ?

My guess is you shimmed it too tight. When I shimmed mine, I didn't use the small shims on the little gears. I tried to, but when I closed it up and tried to turn the outdrives, it was basically bound from being to tight. So I took them out and just used the larger shims under the sun gears. You really have to feel them out. Every diff is different and I have found the newer the truck is the less shimming it needs.
