Does anyone have any experience with these rebuilt control arms? http://www.eagleday.com/suspension.html
I spoke with them on the phone and they claim that these are far superior to the stock ball joint. Even come with a 40 month warranty.

 

Looks like they're using the Rennbay kit for rebuilds.

Actually they machine out the ball pocket slightly to accept a larger ball pin. The common problem with rebuilds is that if the pocket is worn, the re-build won't last very long. They also sell the re-build kits for the standard A arm.
