TL;DR - I have oil leaking from the transfer case where the front drive shaft attaches.
The truck is subjected to a lot of muddy water crossings and over time that muddy water gets in the various seals and things start to leak. That has happened on one of the transfer case seals, so I'll need to replace the seal between the transfer case and the front drive shaft. The part number for this is Transfer Case Oil Seal - Inner Front Drive Shaft (90311-41012) and I'll also need to replace the Transfer Case - Front Drive Shaft Stake Nut (90179-22016) at the same time.
The work isn't done yet, and I'm not overly worried at this point as the leak looks reasonably slow.
