Bad Karma,
I'll give you a tip given to me by one of our other members who is a diesel mechanic and works for a transportation company and I've taken to calling him 'The Deuce Doctor'. RandyLBarnes showed me a trick when it came to buttoning it all back up.
When you get to the point where you've flipped the hubs and are about to put the axle shaft/hub front back in place and are tightening the axle nut, tighten it down really hard. THIS will seat the bearing properly. THEN loosen the nut and retighten it so that is hand tight. THEN one quarter turn past that.
AND DON'T LOSE the small cork piece that goes in the keyway. It keeps the axle end from leaking. After flipping my hubs, the first one I did I MIGHT not have tightened the axle nut tight enough. Or I may have NOT put the little cork piece back in properly. The result is that the first hub I flipped is currently leaking a small amount of oil.
THE UP SIDE is that I've now taken apart FOUR hubs and flipped them all. ONLY one of them is leaking slightly. So I now know how to do it correctly.
IF you have any questions or problems, email me and I'll help if I can.
And it's REALLY no big deal, honest. EVERYTHING is just way larger. And you need to inspect the seals and bearings as they come out and as you put them back in to make sure they are in good shape. I didn't replace my seals, as it wasn't necessary. I did replace the hub gaskets, but they were way cheap at less than $2 each from Saturn.
And BJORN wrote an EXCELLENT technical article WITH PICTURES that gave me the fortitude to tackle this task. While at first it seemed impossible, it really is pretty simple. And I've been working on cars, trucks and bikes for thirty five years.
Good luck.
