Road Testing
Conduct the Road Test under the same conditions as described by the customer to identify the concern accurately.Two people can conduct the test more effectively. While one concentrates on driving, the other can work on the noisy component.
Note:
It is a good idea that the two people change places to compare their results as appropriate.
Apply a load to see if the noise is affected. If the noise changes or is eliminated, retest without the item installed. If the noise is no longer present, examine the part and treat with anti-rattle materials or refit as appropriate. (See Technical Service Bulletin XT910-02 for Squeaks and Rattles Service Kits).
If the noise cannot be isolated, consider adjacent locations and investigate. Remove parts and retest to isolate the affected component.
