I'll say it . . . you'll probably find it is a heck of a lot easier to just remove the whole rear-end - so you can easily work on it, than to try to do all of this under the car. I used to do all sorts of crap on the cement floor of a garage . . . I've learned that I'm not 18 anymore and I like to get stuff up where I can work on it!
For rebuilding rears, I made a plate that mounts to my engine stand - this makes it a whole lot easier!
