Changing Oil in Transfer Case and Rear Axle

[futuruss]

Does anyone change the oil in the Transfer Case or Rear Axle? If yes what oil did you use?

I will be when I get a chance, going to use AMSOIL in both. Using the Signature Series ATF and Severe Gear in the correct viscosity.
I'm hoping changing to synthetic will help with my winter mileage.

edit: Looks like the 75w-140 is already synthetic, though the transfer case it's hard to tell and looks like it may not be based on the viscosity # I found.

By the time spring rolls around I'll be due on my 2019. But in previous years I've used Mopar 75W-140 (MS-8985) gear oil, which is the heavier duty lubricant for the differential, and the Mopar Limited Slip additive (MS-10111).

None of my Rams have had a transfer case.
