For 1990-2009 cars

Basically, squeaks and rattles are caused by improperly controlled relative motion between components. There are three means to prevent squeak and rattles.

• | Attach components securely so there is no relative motion during operation.

• | Separate components so there is no contact under operating conditions.

• | Insulate components so no sound occurs with relative motion between components. Low uniform friction surfaces can be provided to eliminate a stick-slip motion.
