FYI if you do do it, its really easily.

Jack the car up
remove tire
disconnect spindle from strut
remove balljoint nut and cotterpin
seperate balljoint from spindle
place spindle outta the way
rent balljoint press from any nearby parts store
press out old join
press in new joint
put everything back together

I would leave a jack under the control arm, but the swaybar should hold the arm up so the spring doesnt come out
