How do I fill the 231 transfer case
I am trying to check the oil level in my transfer case and top it off to replace what is dripping slowly (another issue).
The red tag on the back of it says 231 Syracuse, NY. I found a diagram that labels the large bolt facing the rear as the filler hole, but what is the giant softball sized sphere obstructing my view and access to this bolt?
Looks like I could loosen two bolts and get the ball thing out of the way to access the bolt on the back of the transfer case.
Is that the right bolt?
What kind of oil should i put in it?
Do I need a grease gun with a hose or a syringe?
Thanks. I am still waiting on the Haynes manual I ordered, if that isn't obvious.

hey thanks for your reply.
i found a nice picture on a jeep site. the two bolt holes here are the drain and fill, and the author on the other site claims this is the 231 transfer case:
looks just like mine. i guess ill just unbolt that plastic ball thing that is right behind the bolts on my dakota and try not to break it. i read that the 231 transfer case should be filled with ATF +4 / Mopar ATF 9602. someone scream if that is not the right goo to put in.
thanks again

Yes, that is a 231. It's quite a thing of beauty.
ATF+4 is the correct fluid.
To get the fluid in there, use a suction gun (do a Google search if you don't know what one looks like).
Correct fill is when the ATF+4 is coming back out of the fill plug (top plug) when the truck is level.

ok, this job went pretty smoothly this morning. i got an oil suction gun and two quarts of ATF +4 from the NAPA down the street. it really only takes one whiff of the stuff to be reminded just how bad it smells.
my transfer case has the 30mm bolts, and there is just enough clearance between the bolt heads and the frame crossbrace to fit a wrench up there. i don't have a 30mm socket, but i will invest in one before the next time i do this. the drain bolt might not be accessible with a socket, but the fill hole has enough clearance for a socket and extension.
i added almost half a quart of fluid before it began running out the fill hole, so the level was pretty low. i didn't have a enough time to do a complete flush and refill so i just topped it off and tightened it back up.
