The intent of the Schley tool is to allow you to replace the compliance bushing without removing the control arm.
In the picture it's looks like you have the control arm pretty much removed except for at the ball joint. Why not spend 2 minutes to remove it from there too?
Two minutes, eh? TBF Crit does live in the mythical land where rust does not exist.
Eh, the less you remove, the better. There is always a risk to separating the ball joint. Sometimes the boots rip. If you use the ball joint air hammer nuts, you will sometimes rip the threads off of the stud.
Looks a lot better than the combination ball joint press, bearing press, and old hollowed out compliance bushing I use. Gets the job done...certainly isn't the easiest way to do it though. That and Honda puts a bevel on the edge of the bushings, so you have to be careful and not slip off, the groove in an official tool would be a godsend for that.
Yeah, the groove in the cup is truly a godsend.
