I found the large socket in stock at Advance Auto Parts, and it was listed as a 4WD axle socket. I had to figure out which one of the 3 worked for my truck, and was lucky enough to pick the right one the first time.
If you are changing the upper ball joint, you also need one of these spanner sockets.

In the package for the upper ball joint you will get the ball joint and large nut that is threaded on the inside and outside. After pressing the ball joint out, the hub will still have that large nut/fitting screwed into the hub, and you use the special spanner socket to remove the old fitting.
The stock nut/fitting that comes in the package is symmetrical and the ball joint presses in evenly. Apparently you can buy an eccentric fitting or washer that change the camber of the hub as you adjust it. The only other way to adjust camber on these axles is to bend metal. This article has some info on camber adjustment.
