Squeaks and Rattles: Description and Operation
Noise Description
* Noises are listed in this section under the area of the vehicle they are perceived to be coming from, not necessarily where the noise ordinates. There may be duplications since a single noise may be perceived to be coming from multiple areas of the vehicle.
Under each noise is listed the problem (symptom), possible cause, and corrective action (diagnosis and repair). If disassemble is required, a reference is given to the section of the manual describing the process.
* When disassembly is required to gain access to the source of the noise, it is advisable to correct other possible noises in that general area before reassembly.
* This information is a guide to some of the more common problems that have been experienced but not a substitute for the user's powers of perception. There is no substitute for a good set of ears.
* Unwanted noises are usually caused by improperly controlled relative motion between components. There are four means to prevent noises after component replacement or repair.
- Attach the components securely so there is no relative motion during operation.
- Separate the components so there is no contact under normal operating conditions.
- Insulate the components so no sound occurs with relative motion between the surfaces.
- Provide a low friction surface to eliminate a stick slip motion.
* To communicate a noise, words must be used. Many different words can be used to describe a noise. The noise description table list noises and their descriptions as used in this book.
