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:
“I am firmly opposed to the government entering into any business the major purpose of which is competition with our citizens ... for the Federal Government deliberately to go out to build up and expand ... a power and manufacturing business is to break down the initiative and enterprise of the American people; it is the destruction of equality of opportunity amongst our people, it is the negation of the ideals upon which our civilization has been based.”
—Herbert Hoover (1874–1964)
“I want that glib and oily art
To speak and purpose not, since what I well intend,
I’ll do’t before I speak.”
