MAINTENANCE AND REPAIR
ON­VEHICLE SERVICE SQUEAK AND RATTLE REPAIR
Squeaks and rattles are caused by the unwanted movement between parts of a vehicle. There are three means to prevent squeaks or rattles. S S S 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.
