BW1359 Where to pour the liquid?

[Alexkebbab]

I need to pour fluid into the transfer case, but I can't figure out which hole to use for this.

That is not a transfer case, even though it looks like one. There is nothing in it except sealed bearings, so as far as I can research, it takes no lubricating oil.

That's weird. I'd have figured Ford used the same open bearings as in a regular transfer case. You can see where the fill would've been, but the doesn't look removable.
