And do I need to replace the whole arm when I do it?

Also when you do your track bar flip the ball joint the other way so your track bar mounts on top instead of underneath. You will never have to worry about it wearing out or getting death wobble... They also sell a nice track bar too and the draglink... Make sure you order the shock mount they do not tell you about for the draglink...
