Compression lower preloaded ball joint

摘要

A compression lower ball joint includes a ball pivotally mounted in a socket. The ball includes a substantially hemispherical bearing with a recess receiving a post of a stud which includes a parti-spherical head adapted to mate with the bearing. A spring is disposed between the post and the bearing providing a preload to force the bearing and stud apart maintaining the joint in a tight condition until a predetermined amount of wear has occurred. This provides a positive indication of when the joint is worn and in need of replacement.
