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. STETHOSCOPE PROBE - Aluminum probe works with the Bluetooth transmitter as an electronic stethoscope for hands-on diagnostics 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.

Tesla states that the rattle noise does not have a safety issue nor effect the performance of the car... well, for the safety issue I cannot comment, but comfort, feel and performance is definitely impacted by this fault! I feel I got a new car!The LUTIFIX Chassis Ear Automotive Engine Noise Finder Tool is a must-have for any car enthusiast. This tool can detect the abnormal noise of an engine, body, and chassis, alerting you to potential problems before they become major. It features LED indicator lights that change color according to the detected volume: green being minimum, red being maximum. I'm in the process of fitting a double cardan prop shaft which should sort the prop shaft angle (standard prop shaft, rule of thumb is good for 7 degrees, double cardan good for 14 degrees). I'm going to have the custom gearbox-propshaft flange tested for run out, and replace the wonkey wheel. USB BLUETOOTH DONGLE - Includes a USB Bluetooth dongle for use with laptop PCs that do not have built-in Bluetooth capability 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.

ACCESSORIES - Kit includes 12 tie down straps, transmitter charging station and a canvas storage bag Describe the above to service in Feb and they first book me in on March 20, then later changes it to July 4 due to parts availability.

So one problem fixed, a new one created... the story of my time as Tesla owner... third time a new fault is created when going in to fix something else... UNBELIEVABLE!!

MULTI-CHANNEL - Connect up to six (6) color coded sensor clamps to different locations to find a noise's source Approximately 1.5 months after last change of 77-C record: 77C_SecondAttempt (online-audio-converter.com).wav The innovative noise cancellation technology hones in on metallic sounds ensuring that only potential problem indicators are heard, allowing them to be easily isolated. Key features You don't want to waste your time or money researching and testing every product available only to find that none work for you. COLOR CODED MODULE - Kit includes a single vibration and noise sensor clamp and Bluetooth transmitter module with a color coded silicone rubber bootMagnetic transmitter units can be easily attached to many different parts of the vehicle and secured with Velcro straps to stop the part from moving during travel.

Chassis ears are a powerful tool for diagnosing vehicle noise concerns as they help pinpoint specific regions emitting sounds and noises. Chassis ears consist of microphones placed in different areas of the automobile, and each microphone will amplify unusual vibrations or frequencies. However, after the change of suspension the steering wheel is not aligned with the wheels... when having the steering wheel level/straight the car slightly turns to the right! COMPATIBILITY - Transmitters and receiver are not compatible with older, STEELMAN 60635 and 97202 modelsFurthermore, it also provides an LED indicator and adjustable sensitivity for pinpointing exact locations for deeper analysis.
