I had the same problem--The top bearing in the case does not get any lube unless it is moving (splash-bath) Good news it is repairable....

amazing. Under what conditions would it not be moving yet the truck is in use?

it moves but it does not engage or use the gear that it supports unless it is in low range. so the gear is free wheeling when you drive down the road unless your in low range. in that case that gear would be locked to the input shaft and the high range gear would free wheel. very simple but hard to explain. powerflow often is!!

not the pto the pto is driven from the rear of the transfer case. i'm talking about the high and low drive ranges.

i'm trying to find a complete unit right now. if i dont i will let you know. they are pretty simple to rebuild tho. if i do choose to rebuild mine i will have to take every bearing out and replace it because i dont trust any bearing after it has had metal go thru it!!

I have a 1968 M51A2 which also has a bearing out of the top of the transfer case. My truck has been sitting for a year now and finally found a later transfer case.
Question: since the dumps and crane trucks, etc move slowly most of the time, how do we prevent the upper end bearings/gears from failure??

those upper bearings and gears are splashed lubed from just the transfer working, what will KILL the xcase is running with the xcase in neutral then they dont get ANY lub, (this is why the -10 says running in neutral is a no-no).the xcase pto set up has a oil pump and line to lub the upper bearings and gears when it is used to drive the rear pump or winch, this operation calls for the xcase to be operated in neutral
You might be able to find a transfer case off a retired pull-out truck from the logging industry. I found one that came from an M52 that had the transmission fail. Seems like low gear and reverse are used the most in pull-out trucks and this is where the transmission fails. Transfer cases are usually ok. Much like buying something at auction though - never sure of what you get.
