NP 200 transfer case rear output housing removal ??

Post by UTTAS »

Hey guys, I may have to pull the transfer rear case output housing to redo my rear output bearing pre-load. I have already removed the companion yoke and seal due to a leak. Upon disassembly the rear yoke was not torqued and had a lot of play. There was no damage to components and this possible pre-load is assuming once torqued to spec that the rear output still has aft play.

My question is this... Will the needle bearings inside the output shaft that are secured by the snap ring fall out when I remove the output housing, see figure 4? Or can I just remove the bolts and slide the housing and gear assembly free of the transfer case?

I do not want to remove the transfer case from the truck and just drop the rear cross member to allow the rear output to slide free, If I have to do the pre-load.

If I recall correctly, as long as the snap ring is in place (and the correct number of needle rollers are present), the rollers will not fall out when the assembly is removed.
