1-59/64" is the technically exact size for the small BJ. Here is a thread for a cheap socket available at any parts store: 2-1/4" 4WD spindle socket; works fine and easy to find locally. Someone else mentions grinding off tangs inside a 1-7/8" 12 point socket as another way.

I ordered this from Amazon when I was working on my truck.

Alltrade 648749 Kit 32 Specialty Ball Joint Socket Tool Set
http://amzn.com/B0028QGT8Q

It is a 3/4 in drive so you will need an adapter. I got a 3/4 to 1/2 impact adapter from Harbor Frieght.

It fit snug and worked really well.

When I replaced the first ball joint in my Aspen, I discovered that a previous owner had decided it was a press-in joint, and after stripping all threads, he glued the new one in place...

If the whole front end is to be overhauled, an alternative way to dismantle it, is to remove the upper arm, clamp the joint in a wise, and use a rod or pipe through the pivot holes for the arm, to turn the whole arm instead of the joint to unscrew it.

I've seen folks tack weld them in. But glue? Neat.
That's also a good way to oblong or crack the the bushing holes. I was using a vice and sockets once to remove old and install new bushings. Got a tiny bit crooked and cracked the lip protruding from the bushing hole. I can only imagine a pipe doing the same thing. Unless you get a pipe that's a press fit into the arm that is.
