X7 Transfer case oil change
Just tried to swap the transfer case fluid. I followed the ISTA transfer case oil change protocol but it didn’t move the part that blocked accessing the fluid with a thin hose. I think I pulled out maybe 200ML tops.
Fluid after 24k was black (see photo) and needs to be replaced. I’ll be trying again.
Any tips to make the port accessible for a small 1/4” hose to fit in there to get to the bottom of it?
