I don't have ball joint issues but was going to check around today about removing the bushings to powder coat my control arms. I guess my questions are answered by Jeff's lack of donuts.
Make sure to mark the orientation of the mounting tabs on the bushings so that when you press them back in, they are in the same orientaion. Jeff punched some marks on the control arms at the end that lined up with the tabs on the bushings, that way when they came back from powdercoat the orientation was easy to find and line back up.
