Removing collar on np231

I am trying to remove the back of my transfer case. I cannot find any information on line about how to take apart the collar that is on the shaft that To the driveshaft. Am I just supposed to pry it off or is it pressed on there?

I've enclosed a picture of it. I just don't know what the part is called. The part that i am talking about is in the center of the picture where the shaft meets with the case housing.

It seems like it is pressed on there. I don't want to try prying it off and break anything on it. From what I can see, the only way to get the "bell housing" off is to get this "collar thing" off first.

I'd put some penetrating oil on it, then grab it with some channel locks and try to twist it to get it broke loose. Then twist it back and forth and try to work it off the shaft. It should be a press fit, but not very tight. It's probably seized on there by corrosion.
