IS there a DIY for X Drive Transfer Case Fluid Change?

I'm getting my parts ready for spring maintenance and i've seen some DIYs on how to change the transfer case fluid. Can it be done without lowering the transfer case? I saw in a post someone recommending a 14MM allen bit and a small ratchet wrench but I can't seem to find the post.

I found these:

Any help would be appreciated.

About changing the fluid without removing the brace, this is what you are referring to:

I did it this way, but if I were to do it again, I wouldn't. Putting and threading back the fill plug is difficult with the brace in there. And while doing so there is possibility of pushing road dirt into the transfer case.

Supporting the transfer case with a jack, even with a scissor jack is easy. Removing the transfer case brace is easy too, but for the long bolt that goes through the transfer case mount. It is difficult take it out because exhaust pipes are in the way, but by lowering the transfer case on the jack and pushing pulling the pipes etc, eventually it comes out.

And you can put it back from the other side when reassembling everything back easily. Next time removing it would be easy too that way.

Transfer case oil is not cheap. You will be lucky to find it for $45.00
