changing the 4 wheel drive gear oil in mazda b2600
Its more than likely that you use 80/90 in the front as well in the transmission, transfer case and the rear. However, I do know that my two wheeler uses what they call "Hypoid" gear oil because of the way the rear diff gears are cut, Don't quote me on this but a lot of people are using synthetic gear oil. I do not know what will happen in the rear diff if you go with it. So stick to what the owners manual. That's if you still have it. It will tell you what all fluids to use how much and when service is due. Oh. And get yourself a shop manual. These things are worth their weight in gold.
