Transfer case oil change question

[milbrath47]

Hey guys!

I am doing the 50,000 mile service on my H3 and I am trying to figure out how to change the transfer case oil . My question is how are you guys getting the oil into the transfer case after draining it? Are you using a siphon or manual pump of some sort? This is no job for a funnel from what I can see........Any other recommendations for the fifty thousand mile service..... I already changed out the air filter, and I heard it is also a good time to change the transfer case oil in the front and rear axles..... I am planning on holding off on that because I have yet to engage in any hardcore off roading.

P.S I already know about the extra fill through the speed sensor
