So the 2 differentials and transfer case can be replaced with mobil 1 75-90 .....can someone please tell me how much is needed for all 3 so I can pick some up for my mechanic to change for me. thanks

I can't recall but it is the spec section of your manual.
Around 6L for all 3.

Thanks JD
I am pretty sure the differentials are pretty easy...remove drain plug clean and let it drain then remove fill plug and fill until it is level with the bottom of the fill plug....is the transfer case similar....I dont even know what or where that is LOL

Always remove the fill plug first.
Then remove drain plug, clean and refill until fluid flows out of the fill hole.
T-case is the same but they use allen bolts.

Any other recommendations besides Mobil 1 75-90?

I've used Castrol 90-weight with good results.
