Help with TMs - Transfer Case Output Seal replacement

[tcruwithme]

I've spent a good amount of time looking through the TMs to find the process to replace the transfer case output seal - with no luck. This is the first time the TMs have stumped me, so any help you can provide is greatly appreciated. Specifically, do you know what TM I should look in and under what section?
