$10 Upper Ball Joint Socket - Really

I've never used a socket.

With the UCA's still in the car, and the boots pried off you'll see the body of the ball joint sticks through the bottom of the UCA about 1/2". I grab onto this with a good sized pipe wrench to break the ball joint free and then use a pair of channel locks to turn it from the top.

If the pipe wrench mars the ball joint body so much it wont thread out easy, knock the burrs off with a file.
