DON'T USE THAT SEPARATOR (Pickle Fork, or whatever you want to call it)... It's really easy to tear the boots on your lower ball joints with it. Of course, if you don't care, new lower ball joints are only $18 ea.

Get a set of Crow's Feet. They're 2-jaw joint separators that let you push the ball-joint's stud out of the fork with a large center-screw. It separates them much faster, and without impact or any other stress on the joint, making it far more likely that you can re-use that part. Plus, it's a whole lot easier than banging on that fork if a joint decides to be stubborn. After I used them once, I don't think I'll ever use a fork again.
