HELP! differential

[mpj76]

I'm so glad to get your imput. The way I did it is that I had to move the car to the other side of the garage. I dropped the car off the jacked and, like a dumbass, started it and put it into gear without locking it all in with the pin. Found the gear on the driveway. Lucky nothing got chewed up. Car is currently jacked off the ground. That differential is a hell of a puzzle. I messed with it a lot by trying to put in one axle, installing drums to hand brake one side in place, wrenches to keep ring gear from moving, putting car in gear to keep other stuff from moving. So, to be clear, I need to keep car jacked up, and remove both axles. Do I keep car in gear? Do I need to remove the "S" spring at this point and try to reinstall later? I've been fighting to keep the "S" in place while moving around the other stuff. I've also put in the large pin back in half way to try to hold the rest together. The other planetary gear and "S" tries to move out without it. Please advise. Thanks a lot.
