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 disassembly is required, a reference is given to the section of the manual describing the process.
When disassembly is required in order to gain access to the source of the noise, 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. A good set of ears is a useful tool.
Unwanted noises are usually caused by improperly controlled relative motion between components. Use the following 4 methods of preventing noises after you complete component replacement or repair:
| • | Attach the components securely in order to ensure no relative motion during operation. |
| • | Separate the components in order to ensure no contact under normal operating conditions. |
| • | Insulate the components in order to ensure no sound occurs with relative motion between the surfaces. |
| • | Provide a low friction surface in order to eliminate a stick slip motion. |
You can use many different words in order to describe a noise. The noise description table list noises and their descriptions as used in this book.
