I probably won't get to dive into it till early next week but the last couple of times it was just leaking from the plate behind the sealed bearings. There are no axle seals on this and the welds aren't leaking. As soon as I pull the axles and reseal the axle plates it is usually leak-free for a year. i know that some of the old brake line mounts had a seal but this rearend is lacking one. How much gear lube are you guys using?
