The KUNTEC 6-Channel Sensor Engine Stethoscope Kit is a one-of-a-kind technology that merges precision results with convenience. This advanced kit is designed to improve the accuracy and efficiency of several mechanical operations, such as metallurgy, building materials engineering, and large-scale equipment cutting. USB RECHARGEABLE - USB rechargeable integrated battery provides up to 8 hours of continuous use per charge You could try looking at the signal amplitudes from a chassis ear on a scope - the low frequency content usually dominates the overall amplitude particularly if you're only looking at a specific problem speed. Use the suspension level changes multiple times a day (parking at home and work raised to very high, lowered to low on the highway most days) Before we talk about using these chassis ears, always be sure to have one person driving the vehicle, and someone else monitor noises. Attempting to drive a car and listen for noises can lead to distracted driving.

If you read my post you would know that the latest attempt to resolve it on my vehicle was Jan 2019. Have no idea which version of the latest revision it was. Indeed, some vehicles managed to make few thousands of km here in Norway and end up with the problem effects as before. As of the time of writing I am not aware of a "permanent" solution. It seems like there are several mitigation attempts, but none of them really succeeds. Rumor has it that there are several versions of the revision 1067361-77-C. At least three. The third being available approximately from Feb 2019 and is failing. Again, the problem might be not the struts, but something else in the front suspension design. Suspension systems have evolved with lightweight components and modified bushings to give the driver a sense of comfort which has also increased the wear and tear on these components. 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? Enter the STEELMAN Chassisear. COMPATIBILITY - Transmitters and receiver are not compatible with older, STEELMAN 60635 and 97202 modelsACCESSORIES - Kit includes 12 tie down straps, transmitter charging station and a canvas storage bag TRANSMITTER JUMPERS - Transmitter jumpers allow separate mounting of clamps and transmitters in confined spaces MULTI-CHANNEL - Connect up to six (6) color coded sensor clamps to different locations to find a noise's source Chassis ears are an electronic device that transmits vibration from suspension points via clamps to a main unit where they are converted to sound. I bought my first set of wired STEELMAN ChassisEars when I was an apprentice and they still serve me well. I’ve used them to diagnose suspension, brake and driveline faults. However, securing the cables into the vehicle to the receiver unit and preventing them from rubbing on the tyres and has always been difficult with one or two casualties on the way. COLOR CODED MODULE - Kit includes a single vibration and noise sensor clamp and Bluetooth transmitter module with a color coded silicone rubber boot

LCD TOUCHSCREEN - 4.3-inch color LCD touch sensitive screen equipped control unit with easy to use interfaceChassis ears allow mechanics to listen closely for abnormal loud noises that might indicate a faulty fuel injector. This way, they can arrive at an accurate diagnosis and take appropriate action to properly fix the problem before it causes any significant engine damage. Final Thoughts about Chassis Ears 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. The kit contains four transmitter units, a receiver unit, Velcro straps and batteries to power the transmitters and receiver all in a blow moulded case. The system is easy to use and can be set up in a matter of minutes. PINPOINT NOISES - Easily pinpoint troubling noises that cannot be duplicated in a repair stall and only occur during road driving
