There are writeups on how to put Toyota diffs in their housings because the stock diffs are weak. Also, a friend of mine has one. It cost him $110 to replace a coolant junction because the air bleed valve was cracked. Disco's are horrible for reliability, but I'll give them this: They sure are comfy, when they're drivable.
