Squeaks & Rattles
Issue:
This bulletin has been issued to assist the diagnostic process in case of a customer complaint of squeaks and rattles.
BACKGROUND INFORMATION
Vehicle noise is inevitable when a vehicle is in use. Current development efforts are aimed at reducing noise levels created by components such as
engine, driveline and tires, but, the quieter these become, the more evident any other unwanted noises will be.
Squeaks are generated through frictional contact of parts. The severity of the noise is a function of contact velocity, material properties, angle of contact
etc.
Rattles are generated through part impact contact between two or more components. The severity of the noise is dependent upon velocity, clearance
(between the components), local stiffness of components etc.
Listed are descriptions of the types of noises from either a Squeak or a Rattle.
Action:
To identify the source of the concern, first determine where the noise is generated. To assist with this, the customer can provide important information in
helping diagnose the noise in question.
For all Squeaks and Rattles concerns and to ensure the correct root cause is identified and repaired, follow the Workshop Procedure below and see the
Squeaks and Rattles Verification Process.
