when i did mine i f'ed up the upper and lower ball joint and the tie rod end wich was already f'ed up. tie rod end at napa was like $30. and the lower was like $40 i think but the upper you have to replace the whole arm but i was putting on a skunk 2 camber kit and that replaces the whole arm and ball joint. to get the ball joint out of the knuckle you need a press. you can pay someone to do it or i bought a cheap press at harbor frieght for $30. ?'s pm me
