Squeak and Rattle Repair




Squeak and Rattle Repair

Squeaks and rattles are caused by the unwanted movement between parts of a vehicle. There are 3 means 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.
