Changing front, rear and transfer case oil?'s

I think I am going to change the oil in the front and rear end and transfer case before harvest and I was wondering what oil to run. Should I put 57-90 synthetic in the front and rear? What oil in the transfer case? Also how much do they each hold thanks. I don't remember when they were changed last so I figured it would be a good time to do it. Thanks

How about some information. What differentials do you have? Is it a posi? What transfercase do you have?
