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:
“The purpose of population is not ultimately peopling earth. It is to fill heaven.”
—Graham D. Leonard (b. 1921)
“A major misunderstanding of child rearing has been the idea that meeting a child’s needs is an end in itself, for the purpose of the child’s mental health. Mothers have not understood that this is but one step in social development, the goal of which is to help a child begin to consider others. As a result, they often have not considered their children but have instead allowed their children’s reality to take precedence, out of a fear of damaging them emotionally.”
—Elaine Heffner (20th century)
“Art for art’s sake, with no purpose, for any purpose perverts art. But art achieves a purpose which is not its own.”
—Benjamin Constant (1767–1834)
