Unfortunately, I believe this differential has served its time.
I think the oil got really hot due to the broken gears and just until it was solid. That's my best guess. I don't see any signs of leaking anywhere, although the rear obviously gets dirtier than the front
Not sure on that, think the front would work more...i did see a great video on the Mazda awd operation-maybe i can find again...i found the front dirty and rear clean on mine at around 27k.
