Jim,
If you are pretty good at this stuff you can do it. I did it once and never again. I used the blueing technique to get the ring and pinion gears back right and had to take the thing apart so many times and change shims that I now have a rear end shop do anything like that. Once you remove the ring and pinion gears they will have to be made to match exactly again or you will hear thet dreaded howl. I am sure some of the more knowledgeable people in the club can tell you an easy way to do it. When I broke my posi track I took my whole rear end to the shop and the guy charged me $50 dollars to set it up with their pre load tester and that was great for me.
