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:
“Culture is the tacit agreement to let the means of subsistence disappear behind the purpose of existence. Civilization is the subordination of the latter to the former.”
—Karl Kraus (1874–1936)
“There are a sort of men whose visages
Do cream and mantle like a standing pond,
And do a willful stillness entertain,
With purpose to be dressed in an opinion
Of wisdom, gravity, profound conceit,
As who should say, “I am Sir Oracle,
And when I ope my lips let no dog bark!””
—William Shakespeare (1564–1616)
“I beg to assure you that I have never written you, or spoken to you, in greater kindness or feeling than now, nor with a fuller purpose to sustain you, so far as in my most anxious judgement, I consistently can. But you must act.”
—Abraham Lincoln (1809–1865)
