screw in upper ball joint ?

yeha I bought the spanner too....I was almost afraid I got scammed if they could just be pressed in...sweet...I think we have the geometry finalized so can order the upper arms this week.

I believe it's supposed to hold 150 ft/lbs of torque. If it slips/strips at 150 ft/lbs, you have a bad control arm.

Well that show what I know. I have never had any experience with these style ball joints. It is interesting that they use a lead that is very shallow, but I guess it effectively cross threads it self into place making it work like a lock nut or tapered thread.
