Re: thread size for balljoints
Research seems to indicate UNF 11/16" x 16 for the stud that screws into the arm.
Just measured an old one I found and the OD is 17.35 (about 11/16") and there are 16TPI. It's a RH stud thread type.

Re: thread size for balljoints
To save having to buy a tap, you could try sawing a cross in the end of an old balljoint and use that to clear the threads.
