What weight differential oil for MJ Dana 44

I was wondering what weight differential oil is best for a front and rear Dana 44 from a comanche. Also how do I find out the oil capactiy of the differentials. I ask this because the rear axle is on a 6 degree shim. It will be a daily driver as well as a part time wheeler, and im planning on using 32 inch tires if that makes a difference. Thanks in advance

90 weight maybe heavier?, and just fill till overflowing. make sure your axle vents are clear.

Well, the way i figure it once its overflowing theres not much else you can do, except maybe drill and tap another fill hole higher up on the diff, but thats JUST an idea and as for the brand i dont really think it makes much of a difference for diff oil, just ask for "gear oil" at your auto parts store and they should point you in the right direction. I run 90 weight, just as an example, dont even know the brand. I'm sure there are "high performance" gear oils, but i highly doubt you are going to need it.

recap: fill till overflowing, use 80w-90 gear oil you pick the brand.

The only stipulation I can think of, is that if your diff is a limited slip you will need an oil additive, dont know about lockers. If'in you do have a limited slip, they have the additive you need at the auto parts store.

Since I am not there to lay my eyes on the jug itself, i would ask the guys from where you bought it from if they think it would be suitable for your application, just to be sure.
