RE: tires keep blowing up, need help
I would also add if you find the center diff has NO oil in it, go through the process of checking all three diffs.
Maybe try a combo of 15,000 in the front, 50,000 in the center and 10,000 - 7,000 in the rear.
If you pull them all out at the same time, use a sharpie pen to mark the F and R diffs so you don't confuse them later.
