The signal from a croc clip mounted accelerometer is amplified so you can listen to it via some headphones.

Faulty engines, transmission, and suspensions can create a range of sounds, as can other components.

The Steelman makes it easy to switch back and forth between channels with a simple press of a button.

There is part of the shock that come loose internally and rattles inside and you hear it at low speeds. It features LED indicator lights that change color according to the detected volume: green being minimum, red being maximum. I decided to give their wireless kit a chance, and the microphones don't work with Samsung Bluetooth.

A set of included full-coverage, professional-style headphones shut out surrounding sound letting you focus on what the ultrasensitive microphones pick up. The newer STEELMAN Wireless ChassisEar is an essential piece of diagnostic hardware when it comes to identifying and verifying squeaks and rattles in the modern vehicle.

Sensors easily clamp onto problem areas of cars and trucks including springs, torque rods, shocks, body mounts, brakes, dash assemblies, door hinges, drive trains, rear or front axles, transmissions, transfer cases, suspensions, sway bars, tie rod ends, struts, axle hubs, ring and pinion bearings, mufflers, catalytic converters, O2 sensors, A/T cases, oil pumps or even un-torqued bolts. For instances with confined spaces, cable extensions are included for each transmitter that allow clamp and transmitter to be mounted separately. Our selection of innovative tools includes diagnostics devices, inspection lights, maintenance tools, tire repair supplies, and traditional hand tools. So it is certainly struts that get challenged by the problem which is UNKNOWN and is never been communicated to me so far. Indeed, some vehicles managed to make few thousands of km here in Norway and end up with the problem effects as before.

Working as a high powered wireless stethoscope for your car or truck, each of the 4 independent transmitters can be placed in a separate location around the vehicle using the built-in clips and magnets or the included nylon hook-and-loop straps. In the modern motor vehicle there can be multiple suspension mounting points that could be the cause of that squeak or rattle so how do you diagnose which one it is? When it comes to noise diagnosis the STEELMAN Wireless ChassisEar can be used on multiple systems from fuel injectors to under dash squeaks.
