IF your ball studs are perfectly round tighten the screws until you coil bind the spring & then back it out 2-3 turns . This will prevent "DEATH WOBBLE" . If your ball studs are worn some you will need to set this at the tightest point . Usually opposite of it's working position . If you don't do this it will bind when you turn due to the ball being thicker where it isn't worn . Real simple stuff & search "DEATH WOBBLE" . You will see the wobble thing is commom & CUREABLE !!!
