Just wanted to add my experience to the list: I took delivery at the beginning of 2017 of a new inventory MS P100D so I'm assuming Q4 2016 build, and almost immediately noticed the rattle/clunking noise in the front suspension being discussed in this thread (#1 in the quoted wav file). I finally got it replaced at the beginning of this year after reading that this was a common issue with no known fix, hoping that by now it would have been fixed.

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. 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.

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. Once of the great things about wireless chassis ears is not having a bunch of long cables to tend to. No more worrying about a cable becoming loose and getting caught in the axle. Something I have seen happen before. Positioning the transmitters in the proper locations is key for accurate diagnosis. Since the Steelman kit comes with four sensors, you can place the sensors in different locations to really pinpoint the noise. You don't have permission to access "http://www.homedepot.com/p/Steelman-ChassisEAR-Diagnostic-System-06600/300088433" on this server. 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.

So while I have a Model X those with the same symptoms, especially those who had replacement struts, might want to have the SC do an inspection on the sway bar bushings. With so many Chassis ears products on the market, it can be hard to know which one is right for you. The OUFKAR Chassis Ear Automotive Engine Noise Finder Tool is an innovative 6-channel detector designed to help detect and adjust abnormal engine noises. Featuring a host computer with the integrated 6-channel signal receiver, this tool is uniquely equipped to locate the source of vibration caused by bearing, gear, valve, crank, or cylinder failure.Currently at 15.5K miles and 2.5 months since, and the rattle has not returned yet nor any other sounds. 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. So it is certainly struts that get challenged by the problem which is UNKNOWN and is never been communicated to me so far. All we know is that it started happening after post-April (aka facelift) 2016 changes in front of the vehicle. 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.

STETHOSCOPE PROBE - Aluminum probe works with the Bluetooth transmitter as an electronic stethoscope for hands-on diagnostics 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. 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. When diagnosing a vehicle noise, the options for chassis ears can be overwhelming. Wireless chassis ears have become increasingly popular lately, with many mechanics touting their ease of use and convenience.Furthermore, it also provides an LED indicator and adjustable sensitivity for pinpointing exact locations for deeper analysis. The OUFKAR Chassis Ear Automotive Engine Noise Finder Tool offers small businesses and professional mechanics a comprehensive diagnostic solution that saves time and money in their daily operations. Things to Know 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! 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!! Chassis ears, wireless or not, are a great addition to a toolbox. Isolating suspension noise is just the beginning. Almost any type of noise can be detected by the transmitters units. Things like wheel bearing noise, transmissions, alternators, power steering pumps, even fuel injectors can be tested.

USB RECHARGEABLE - USB rechargeable integrated battery provides up to 8 hours of continuous use per charge COLOR CODED MODULE - Kit includes a single vibration and noise sensor clamp and Bluetooth transmitter module with a color coded silicone rubber boot 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 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. Although you won’t need assistance maneuver the cables, wireless chassis ears stress reliance on batteries. Therefore, when deciding between wired or wireless chassis ears to diagnose a vehicle's noise, it is essential to weigh all the pros and cons, such as price point, battery life, and sound capabilities.The transmitters span four channels to allow the user to easily identify the source of the sound with the supplied headphones.
