np 241 transfer case Q's - Pirate4x4.Com : 4x4 and Off-Road Forum

I have a gmc 2500 with an np 241 behind an nv4500. This case has been nothing but trouble for the last few months. I want to replace it with a different one.

What I want to know is what transfer cases that I can swap in place of it. I'm not worried about reworking the mount or drive shafts. Just wanna know which transfer cases will bolt directly in it its place. I don't want to buy any different adapters to bolt it to the transmission that is.

241 is a decent unit. id swap in a new one (or rebuild yours) or go aftermarket. but to answer your question a 208, 231, 300 and 261 should all fit. any of the work is worth doing is up to you

What problems are you having with it? The only thing I've had issues with is the CAD (central axle disconnect) with that goofy gas expansion system for engagement. I replaced mine, but I'm going with either the electric motor or cable system if it goes bad again.

My problems with it are that it won't stay in 2wd and now it won't stay in high range at all. It makes clunks and grinding noises. I can get around in 4 lo right now without any noises or problems. So I guess I need to take it apart and see whats going on in there.
