From what I have heard the upper knuckle is in the way for a regular press in situation. If your press has enough depth so that you can weld up a jig which will allow you to press from the other side of the upper knuckle then you should have no problem. You may want some kind of fitting which will keep from damaging the ball or its threaded end when applying pressure. Be sure to share pics if you do it successfully,,, and tell what went wrong if not successfull..... Greg
