Steelman Wireless ChassisEAR Auto Diagnostic Tool Kit, Identify The Cause of Troubling Vehicle Noises, 4 Transmitters with 50-Foot Range

This was used on a Dozer that needed to work in tight spaces. I couldn't figure out what was making a noise in the front of the engine, so I used the tool to help me locate the area in the back, and then I connected the ears to various locations within that area. What appeared to be a front-end issue turned out to be a problem with the rear-end pump system. The noise was being drawn to what sounded like the front of the unit by the fan and design of the dozer. It worked perfectly, and I was able to locate the issue without wasting time working in the incorrect area. br>I also used it to locate a knock in front of my vehicle. I took it to three different shops in addition to the dealership. They couldn't find the source and wanted to charge me for replacing parts that weren't necessary. Using the ear chaser, I was able to narrow down the source of the problem to a simple split bushing in my suspension. It was a simple $18 fix. Instead of $800, you'll pay 00 for the part. 00 purchased in a store The price on Amazon was the best I could find, and it was well worth it. This is an excellent product.

It sounded like a hose gently slamming into metal. Several episodes of jacking up the car and inspecting/securing bolts, bushings, sways, fuel tank straps, sheet metal shields, bumper clips, trunk bump stops, exhaust tips, brake hoses, and other components. I was finally fed up enough to think about the Chassis Ear's price tag. One of the microphones, the one I mounted on the sway bar, picked up the noise source during a single, instrumented test drive. It was the sway bar-to-link-stud connection. That connection was strong enough that manually pushing and pulling the sway bar ends produced no noise or movement. The Steelman Chassis Ear was quick to pick it up. The bar end made an audible click only after the sway bar mounting bracket was removed. br>br>Tighten up the sway link to the bar and there's no more clink noise!br>br>I had previously ruled out the sway bar because a manual test with the bar ends manually stressed produced no audible sound and it felt solid. The hidden culprit was discovered by the Chassis Ear. br>br>Getting rid of the annoying clink was well worth the money. br>br>For securing the transmitters, included velcro straps were a must. I'm glad I purchased the wireless version of the game. It would have been a pain to route multiple wires. br>br>Aside from the transmitter on/off slide switches being extremely difficult to slide, the system was built reasonably well.

This tool's concept appealed to me greatly. 1. br>br> First impressions and unboxing: br>The unit itself was in good shape right out of the box, but I had to use a thin blade to pry the battery door open because the ridged section deflected inwards but wouldn't slide, and the "1" button sat at an odd angle but otherwise worked. br>br>All four transmitters worked when pre-programmed. Two of the sliders didn't click solidly into place during testing indoors. br>br>Of the four clamps, three worked and one didn't, despite my best efforts to rotate it and blow the connector out with compressed air. Actual application: br>br> br>While the magnetic mounting may be adequate for underhood diagnostics, I was trying to isolate a vibration at highway speeds. Although the zipties that came with the kit were a little short, the method of attachment is quite effective. I did ziptie the top through the included slot, but I doubled up and placed one over each unit near the bottom to keep them from flopping. br>br>All three of the working units that I was able to install on the car initially worked. One sent out a weak signal and then stopped transmitting, whereas the other two were fairly consistent. The clamps did come loose a few times, but I believe this was due to my positioning/driving style rather than anything else. br>br>I was pleasantly surprised by the audio quality, which far exceeded my expectations. After trying a new set of batteries (just to give them a fair shake with the transmitters), I'm going to give them another shot, but my initial impression is that the microphones are unreliable. br>br>I did some research to see if the transmitters will accept other microphone designs. This could become my new favorite tool if this is possible and results in increased reliability. br>br>I'll rewrite this after I've tried it with different batteries and different mounting options. Steelman deserves praise for creating a unique and attractive design.

The transmitter's magnet appeared to be weak, but it was strong enough to keep the unit in place. To find the source of the suspension noise I was hearing, I wrapped three of the four transmitters around my front wheel sway bar and strut tower. I went for a short drive, and all of the transmitters remained in place, allowing me to switch between them to hear what was coming from each location. It's great that this setup is wireless from the transmitters to the receiver; positioning the microphone clips and securing the microphone wires out of the way is simple and allows for a wide range of placement options. While I haven't yet found the source of my noise (it'll take a few more tries), I am confident that this will make the job much easier because I was able to hear the various sounds emanating from the various attach points during my drive.
