Once the arms are off, and depending on the availability of tooling, the ball joints and bushings can be removed. We set up the arms in a vise and used a grinding wheel to grind off the heads of the rivets that were holding the ball joints in place. Next, we pried the ball joint off, but we had better luck using an air-powered hammer. For the factory bushings a special press must be used, or as an alternative you can get away with a large hammer. Still, we suggest taking the arms to a qualified suspension shop to get them removed correctly.
