I did bleed it. I probably have an hour of run time on it at this point, turning the wheel lock to lock.



Sounds like you've got a bad box. I'm sure someone will chime in and tell you what the issue is.

I would just change the seals on the old box (<$10) and put it back in. I changed the input shaft seal in ~10 minutes, which solved my leak I had a few months ago.
