Ford makes the ball joint as one piece. Its riveted on. Ford would tell you that you'd have to replace the entire control arm to do the job, and thats true, but companies like Moog have come out with kits that allow you to drill out the rivets and bolt on a replacement (they are greasable too!!). Unfortunately, these kits are only available for 00-04 cars at this time, so if you had 05 spindles, you'd need to buy 05 control arms from Ford to get the job done. They run about $85 IIRC.
