np242 rebuild?

there's a good chance i've got a toasted tcase. it's a 242, and i haven't the foggiest clue about rebuilding it or any other tcasefor that matter. if any of you fine jeepers that do know how to rebuild it would like to teach me how/help me if i end up having to rebuild, that would be pretty cool....

What makes you think it needs a rebuild?

They arent too hard to work on, but if you only do oil changes you might want a friend around who knows what they are doing.
