For 1990-2009 cars only
Basically, squeaks and rattles are caused by improperly controlled relative motion between components. There are three means to prevent the squeak or rattle.
| • | Attach component 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 stick-slip motion. |
