2nd Gen Non-Engine/Transmission Transfer Case Help

[JSykes]

I am in the process of tearing down my NV241HD transfer case to fix a couple of leaks. I have pulled the drive shaft to replace the seal. Also, I need to remove the rear extension housing to replace the leaking gasket. The extension on my transfer case is one piece and the factory service manual shows it in two pieces. (The manual refers to a snap ring and snap ring cover that I do not have on my TC). I removed the four bolts that hold the extension to the transfer case. The extension will move about a 1/4" before meeting some resistance. Is there anything else that I need to remove to get the extension and gasket off? I don't want to yank this thing and tear up my TC.



Is there anybody else (NAPA, Auto Zone, etc. ) that sells these gaskets and seals for the transfer case? I am walking kinda bow-legged after buying them from the dealer ($50. 00 for a gasket, come on now!)



Anybody done this repair before and have some advice?



Thanks,



Jay
