Never fails: do something fun, then a maintenance item acts up.
Drove it to work on Friday, smelled a little burny if that makes sense. Came home and saw a drip hanging off the transfer case flange, between it and the driveshaft.
Took it apart tonight to see and the little seal inside the flange had a notch f'd up on it. Not the main outer seal.
Having a hard time track this down. Luckily I know a guy that knows a guy.
