7. With all the cotter pins removed, I loosened the ball joint nuts and smacked the areas where they are. This will " shock " the ball joints loose. If you use a pickle fork, or ball joint separator, you will usually destroy the rubber grease boot. If you just smack the side of the spindle where the ball joint stud is, the shock will release the stud so you can remove the spindle and not hurt the grease boot.
