To be completely honest with you... Unless you have access to somce specialized tools and want to put a lot of hard labor into it. You are much better off having this done by a repair shop. Once you replace the ball joint, it has to have an alignment. you might be able to get it close enough to drive it to the shop and have it aligned. Also, some ball joints have to have rivets drilled out, and some don't. some require some heavy banging on with a hammer to loosen, some require impact wrenches. All are a lot of hard work.
