So I tracked the leak down, gear oil is leaking from around the driveshaft where it comes out of the front of the transfer case. Looks like there's a seal there, but what steps do I need to take to remove the driveshaft? I'm assuming the transfer case will have to come off, but I'm not sure where to start. Is there anything holding the driveshaft in, or just a snap ring? Please help! Thanks

 

Anybody know?
Looks like the fill line is about the same level as where the driveshaft comes out of the housing, maybe was overfilled? It started leaking after being driven hard on night. Any help would be great.
