T-Case and Differential Fluid Change Questions
So I've looked around the forums here using the search tab and have not found a post that fully answers my questions I have. My car just crossed 128k and from what I know has never had the t-case or differential fluid changed. While the car doesn't show any signs of excessive wear at this point, I want to change the fluid now rather then when something comes up.
So my questions are for draining and filling the fluid out of each system. Can I just use a regular fluid pump? Or do I need to make some sort of custom fitting for each system to get the fluid out? I'll attach a picture off of google to show what I'm trying to describe.
Could the orientation of the vehicle help when using a regular fluid pump? So for example having the front end raised or back raised, or ether side.
Lastly is flushing required? Or can I just fill each system up until they are not accepting more fluid after draining the old fluid out?
I apologize since I know there have been many posts on this topic. My mechanical skills and access to tools are fairly limited, so I was hoping the clear my confusions up so I can tackle this project asap.
Thanks,
Andrew

Lots of posts on how to change transfer case. Do a search on here. Differential is straight forward. Suck out fluid with pump, fill with correct fluid.

Btw, the transfer case is a fraking p.i.t.a. Look up my posts on changing fluids in transmission, transfer, differential, power steering. The pump I got had a very small black pipe adapter that when you remove the plug on the transfer case, the gears are right there interfering with getting the suction through and back towards the rear of the "holding" tank part. It holds so very little fluid to begin with, I wanted to get everything I could out before filling.
I chose the "14 second" method for my transmission and was very happy with the results.

replacing the transfer case oil is quite a simple job in itself, its jacking the car up 21" twice thats the PITA.
i recommend at least loosening the drain bolt before getting it up in the air in case it doesnt want to come out.
a 5' length of garden hose will fit inside the plug hole and can be fed through the wheel arch.
add a funnel in the end, that way you can easily get the new oil back in from the comfort of standing next to the car.
trying to get the new oil in from under the car is not the way to go.
this is not a job i would trust to a local mechanic
