Improperly controlled relative motion between components causes squeaks and rattles. Refer to the following list in order to prevent squeak and rattles:
| • | Attach the components securely so there is no relative motion during operation. | 
| • | Separate the components so there is no contact under operating conditions. | 
| • | Insulate the components so no sound occurs with relative motion between components. Low uniform friction surfaces can be provided in order to eliminate a stick-slip motion. |
