do you use these with the hotchkis upper A-arms? great vid btw!
Just screw them in.
These Howe ball joints take maintenance. We run them in the circle track cars I used to help with. The lash is set with a 1/2” male socket head from a ratchet, extension, etc. That screwing motion tightens the cup against the ball of the stud. Then there is a set screw to keep the cup from unscrewing itself.
I’d catch them loose every few races. About 100 laps with practice, qualifying, race per race weekend.
Take a paint marker and draw a line across parting line of the cup and body.
These are not an install and forget it part like stock ball joint. Check every 5000 miles, every oil change...
