Purpose
Ball joints are the pivot between the wheels and the suspension of an automobile. They are universally used in the front suspension, but can also be found in the rear suspension of a few higher performance autos. Ball joints play a critical role in the safe operation of an automobile's steering and suspension.
In automobile suspension nomenclature, the upper ball joint is called the "upper ball joint" and the lower is called the "lower ball joint". Lower ball joints are typically larger and wear out faster as the entire front end weight rests solely upon them.

Famous quotes containing the word purpose:
“It is my purpose to disclose the mystery at once, and to ask you to look for your interest,—should you choose to go on with my chronicle,—simply in the conduct of my persons, during this disclosure to others.”
—Anthony Trollope (1815–1882)
“Productive collaborations between family and school, therefore, will demand that parents and teachers recognize the critical importance of each other’s participation in the life of the child. This mutuality of knowledge, understanding, and empathy comes not only with a recognition of the child as the central purpose for the collaboration but also with a recognition of the need to maintain roles and relationships with children that are comprehensive, dynamic, and differentiated.”
—Sara Lawrence Lightfoot (20th century)
“Happiness serves hardly any other purpose than to make unhappiness possible.”
—Marcel Proust (1871–1922)
