So I did my rear centre section and it also drained approx. 1.2L Colour wise, not as bad as the Transfer Case. I'm at 50Km(30ish mile).
Centre Section.
Also did the Transfer Case, and as everyone says the colour is awful.
I did some custom tooling
. (cut most of a socket off, allen key and was able to fit a ratchet and a torque wrench in
I did cut a bit too much off the socket tho.).
Also decided to stick borescope into the TC, and yep it really needs a drain plug. There looks like some baffle/sections that run the length of the TC that are internal. I was only able to get 600ML before giving up.
