a ball joint assembly having:
a ball joint and stud that are centered about a first centerline and mounted in a ball joint cup that includes a radial extension that supports a mounting body;
the mounting body is centered on a second centerline and has an outer diameter that complements the predetermined diameter of the aperture in the frame and a threaded stud;
