Threaded Ball Joint Assembly, Hillman, 1/2 in x 20

A ball joint is a steel bearing stud and socket enclosed in a steel casing. It fits into a tapered hole in the steering knuckle. A protective casing prevents dirt from clogging or damaging the joint assembly. Motion control ball joints tend to be retained with an internal spring which helps prevent vibration problems in the linkage.
