    i have just aquired an np205 transfer case. i am not too sure of the condition of the internals but am planning on rebuilding it anyway. is there any good tech sights that would have breakdown info and parts listings? and if so, could someone please point me in the right direction?? thanks

    The only thing a 205 might need is bearings. and pinion seals. If the bearings on the shafts seem tight I wouldnt bother with a rebuild.

    4xheaven in NY(1-800-800-1679), has a complete rebuild kit, bearings, seals, gaskets for about $130, they also provide tech support. Also, Steven at ORD can help to.

    I did it this previous weekend...some of the snap-rings are kinda a pain but it is pretty simple...You also need a couple BIG sockets (like 1-1/4" fo rhte front output yoke and a little bigger one for the idler shaft locknut and the rear output yoke..)Not too bad though...also, the roll pins that hold the shift fork to the shift rail...those were tehe hardest part of the entire rebuild for me...

    got the sockets but i don't know if i am going to be getting in over my head. i can fix stuff if i have to but get a little lazy when it comes to stuff i don't HAVE to have done, you know. this will be my first time doing this and i have a good friend that seems to know how to fix anything (nothing has broke yet). i guess we will see

    My chiltons guide had a great section about the 205. It has an exploded view and step by step instructions to disassemble it. BEWARE of the needle bearings and pilot bearings...they will fall all over the place. I lost 2 pilot bearings and had to "borrow" a few from a buddy's 203 he had laying around...Other than that it is easy.

    Speaking of needle bearings, the best tip I've heard with them is to leave a couple out while your assembling the unit, then once you get it together then take a hammer and a small punch and tap the remaining needle bearings in. But I've never seen the inside of a 205.
