The only tool so far that I can imagine to work is this
Neck Bearing Race Puller, Steering Neck Bearing Race Remover Metal for 1‑1/8in To 2‑5/8in ID Races https://a.co/d/9xJ25fs

No clue if it will work or not. I have some ideas of tools that could possibly work, but I haven't found them in existence (only in my head).

If this tool doesn't work, I will try packing toilet paper!

I just rebuilt one of these last August. No worries on heating the case section and trying to rig a puller to get it out. Just slice where the notch is with a Dremel type tool and a larger diameter disc (I used one from 'Gyro'), or a pneumatic tool with a cut-off disc. Slice it all the way down, then bend it inward from there. I was cautious to avoid stressing the walls of the bore very much as cast aluminum isn't very forgiving. To install the new one I left the new bearing in a freezer for a while, lubed up the bore, and pressed it in on a Harbor Freight press.

Believe it or not, nothing at all...
Was just one of those "while in there" things...I know, not very typical, but I just thought I'd rebuild it for "fun"

Thanks Tempest, that's exactly what I did on my "practice" transfer case.
Cut half of the bearing, then was able to knock out the needles. Then I was able to get a blind puller in there, gran the upper side of the bearing from the inside and pull it out.

I was just wondering if there was some specialty tool to do this job "clean".

BTW, did you replace all the bearings? If so, where did you buy your bearings? Did you buy a kit on individually?

I bought the bearings and seals as kits from Cobra Transmission. Everything was correct and fit without issue. I don't know how far you are into yours yet, but I screwed up a metal shield on the main shaft when I was trying to get it apart. The main shaft is pressed out in such a way that the bearing remains in the front half of the case. Once that main shaft is out, then you can remove the bearing after removing a retaining clip. Initially I thought the beating stayed on the shaft, so I tried inserting a punch and tapping on what I thought was the bearing as seen from the front with the seal removed. It turned out not to be the bearing, but a thin steel shield that sits between the bearing and the seal...Lord only knows what purpose it serves. The LWX500 transfer case is actually a simpler, but more robust version of the NV125. It doesn't have these extra bits, and comes apart much easier.

I think you can order it from cobra transmission as well.
I've taken everything apart, just waiting on that bearing, it's taking forever.
I thought it would be a one day job, but it's been almost a month now.
Hopefully I get the bearing next week and can complete it.
Don't feel bad about the metal shield.
I didn't realize the shaft had snaprings on both sides, and I ended cracking the whole case while pressing it out.
So had go find another used transfer case lol...
I did record everything on video, so once I'm done, I'll post it. A lot easier by looking at the actual pictures to understand what's going on.

Finally got the bearing and the answer from SKF




Not sure why they're saying 6011-ZNR/C3
Z stands for shield on one side, and the original bearing did not have any shields, so I don't think it's necessary.

Now the TC is ready to go back together!
