also, if i swap the trans/tcase, should i replase the output shaft snap ring? ive been told that it is a common problem. what else should i do to the trans/tcase to prevent issues in the near future? it has 112k miles on it, thank you for your help

 

Should bolt right in then.

 

are the 231 and 241 transfer cases interchangable?

 

Don't just replace the snap ring, replace it with a Transfer Case Saver. It completely eliminates the trouble prone snap ring.

 

Kinda. There ARE some differences. If that is the route you choose to go, get one from a donor truck same body style/bed length as yours, and grab the driveshafts as well. You can get hybrid u-joints to go from the larger shafts, to the half ton axles.

Bear in mind, 241s out of a diesel, or v-10, will have a different input gear, than the V-8 versions. (there were no v-6 3/4 ton 4x4's.)

 

does it have to be off of a manual trans or does that matter? and thanks for all the help

 

I think the input gear is longer on the manual..... I think.... It *might* work from an auto... not sure on that one.

 

so I pulled the transfeer case and replaced it with a 231d, got it all back together fine and it still makes the same noises, in first, second, and third gear. also, the tcase that i pulled has a place for a three wire connector and the new one doesnt, can i switch rear output cases? and the speedo doesnt work, it dies when i brake to a stop, and the tcase shift pattern is different. any ideas? the old tcase is pretty wasted, the seals are leaking badly and show wear

 

Trans problem? You have the NV3500??

 

yes i have the nv3500
