• | 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. |
