Squeaks and rattles are caused by the unwanted movement between parts of a vehicle. There are three to prevent squeaks or rattles:
| • | Attach the parts securely so that there is no relative motion during the operation of the vehicle. |
| • | Separate the parts so that there is no contact during operation. |
| • | Insulate the parts so that no squeaks or rattles occur with the movement of the parts. Low uniform friction surfaces can be used to eliminate stick-slip motion. |
