Different and transfer case fluid change
Just replaced my front + rear diff and transfer case fluids to Amsoil Severe Gear 75W90 at 59k miles.
The rear diff and transfer case drain and fill plugs are obvious, the front diff plug can be accessed after removing the skid plate beneath the oil pan.
Front diff and transfer case takes 1.5qts
Rear diff takes 3.2qts

Can you share some details about the procedure? Did you need to jack up the truck? Also, did you use 6pt or 12pt socket? I understand these can get rusted on pretty tight. 12pt might make it easier to access w/o raising the truck, but might round off the bolt. I was planning on doing mine at 30K miles.

jditom, I bought the truck used at 51k, this is the first change during my ownership, the fluids didn't look too bad so I reckoned the previous owner had it changed at least once.
I had the entire truck raised, fronts up a pair of Rhino ramps and I jacked up the rear on the rear diff housing before sitting the rear axle on a pair of jack stands.
I would highly recommend raising the truck for room to work especially at the transfer case and front diff, more room for arm motion when doing manual pumping during the refill of gear lube.
Then I used 6pt sockets to remove the rear diff and transfer case fill and drain plugs. I used a socketed allen key for the front diff plugs.
