Leaking Front Diff

Need help guys. Have never had to deal with my diffs before, but today, after a full day of heavy wheeling, I noticed a ticking sound when we got back to paved road. It was a steady, rhythmic ticking sound that seemed to be directly related to the rotation of the wheels. Sounded like a twig stuck in the wheel or something, but when we stopped, I saw that the back end of the front diff was soaked in fluid, coming out of where the front driveshaft enters the diff. I put some more fluid in it, though it was already pretty full, and made it home fine. But now I gotta figure our how to fix this leak. What do I do guys? And would the tick be related??

Related, maybe, and maybe not. You will have to located and diagnose the ticking. One might supposed that some diff fluid pushed out the vent tube or past a seal. Keep an eye on the area, and on the fluid level in the diff. If the leak continues long term, you may need a fresh pinion seal.
