Np241 transfer case leak

[End3r]

Hey all, I posted on the year-specific board back on Monday and got nothing so I figured this is probably the better place for my question...

So my transfer case (np241 in an 89 suburban) is currently leaking pretty bad from around the shift linkage rod (at this point enough has leaked out that im gonna top it off again before I drive the truck any more). From what I can find online it seems like it's just an o-ring that seals up this location.

Just wondering if anyone has had any luck or thinks it's possible to swap this out without dropping the transfer case all together and tearing the whole thing apart? Everything I'm finding is just complete teardowns and they dont really address the shift rod seal at all and just tend to leave it alone.

I'm pretty sure the shift shaft comes out front the inside and slides out. Then you can access the shift shaft seal. I believe it requires teardown. Can probably be done inside the vehicle if you feel like it.

Transfer case weighs about 80lbs, pretty easy to bench press. If that oring is shot, I'd think the rest of the seals, pads, would be iffy.

Get one from a junkyard and rebuild it or just reseal it.
