Which is the most likely tool for a technician to use to find a noise traveling through the suspension system?

A technician is most likely to use chassis ears to find a noise traveling through the suspension system. Chassis ears consist of microphones attached to various parts of the chassis that allow the technician to pinpoint the location of the noise. By placing these microphones strategically, the technician can listen to different areas of the suspension system while the vehicle is in motion or under load, enabling them to identify the source of the noise with greater accuracy.

In contrast, while a vibration analyzer is useful for diagnosing vibration-related issues, it may not be as effective for pinpointing specific noises in the suspension system. A test light is primarily used for checking electrical circuits rather than diagnosing mechanical noises, making it unsuitable for this scenario. A scan tool is mainly utilized for reading diagnostic trouble codes and monitoring vehicle systems electronically, but it does not assist in noise diagnosis in mechanical components like the suspension.
