That could be a problem. I knew a guy that worked at Cheyenne Mountain during the Cold War. I think that dealing with all that insane NORAD security crap drove him to be the crabby old fart he is today. I would definately try to line up a secondary mode of transportation before I tore into something I didn't know if I could get back together in time to go to work in.
Those auto hubs are really complicated to get back together right. When I took mine off and saw all those little springs and various parts, I just went ahead and got some manual hubs instead of trying to put the autos back on. Now I have to get out and lock them, but I know for sure they're locked.
Two peices of advice that I've learned through experience:
After you get the cover off the auto hub and take the first spring and little flat piece out and get the snap ring off the end of the stub shaft , you'll have to get this ring off that goes around the inside of the rotor and holds the hub in. On the auto hubs, this ring has two little tabs, one on each end of the ring. Pull these tabs together to get the ring out. I was almost ready to kill something until I figured this out.
Second, when you go to put the snap ring back on the end of the stub shaft when you put the hubs back on, there's a groove cut in the end of the shaft about 1/2" back from the end of the splines. This is where the snap ring has to go, but lots of times the shaft will be too far back in the rotor for the groove to show. Don't get mad, get glad. Just reach back behind the knuckle and pull the shaft towards you. This will pop the shaft out just enough to expose the groove and let you put the snap ring on. Took me a minute to figure that one out too.
Good luck.
