For 1990-2009 cars

Squeaks and rattles are caused by improperly controlled relative motion between the components. The following are 3 steps used in order to prevent squeaks or rattles:

• | Attach the component securely in order to ensure that there is no relative motion during operation.

• | Separate the components in order to ensure that there is no contact under operating conditions.

• | Insulate the components in order to ensure that there are no squeaks or rattles occurring with relative motion between the components.

| Low uniform friction surfaces can be provided in order to eliminate "stick-slip" motion.
