Axle refuses to come off the stub shaft. Halp!
Update: big time fail. Couldn't get apart no matter what I tried. Even tried swapping tripods out and leaving the old axles. New and old axles not compatible with each other. So I just lobbed a crap load of new grease inside the old one and put it back together. Hopefully it holds for another couple thousand miles until I can get in for a second try.
