Sliding off coarse a bit...That double gear GB has sitting next to the transfer case is the intermediate gear which runs on the caged rollers that failed for me. In my case, the gear was an NOS Willys gear, the teeth survived but the inner bearing surface was wrecked.
The solution, the rock crawler guys have come up with is you send the gear to herm the overdrive guy in WA state and he machines the gear to take a timkin bearing cup on each end , then timkin bearings sit on a shaft with a shoulder and you set the pre load like a front wheel bearing. Very strong and runs quieter, saved my original gear.

GB those Koyo bearings look well made. Carry on....
