STEELMAN ChassisEAR Electronic Squeak and Rattle Finder Auto Diagnostics Tool, 6 Microphone Clamps with Leads, Over-Ear Headphones

Works as described. The set as purchased is very handy. It does require a bit of effort to hook the leads, write it all down, route the wires, then take the drive, repeating as needed. But if you have to find the source of a noise, this is really the best way. The headphone earpieces swivel around to face outward so you can hold one earpiece up to your ear and hear without having to actually wear the headphones. For those of you not sure about these things: I used to work at new car dealerships as a mechanic. This is one of the tools we used. I do remember some leads not working after a while. I'm not sure if it's abuse or quality that caused maybe two out of six to stop working after a while (a year or two). So many different people used the set. That was over a decade ago. I had no concerns ordering a new Chassis Ear for myself due to this potential issue. All six are equally loud and clear on my new, personal set. I tested them all initially by hooking them to the back of a quartz clock to check sound quality before going through the effort of hooking them up to a vehicle and routing the wires the first time. Loud, clear tick-tick-tick from each as the seconds ticked past on the clock. Nice. I used to use these using a cassette adaptor instead of the headphones, playing the output through the cars stereo. Worked great like that. I don't have that option on my truck. I was able to hook the individual microphone leads directly to my Olympus WS-300M (yeah it's old) digital voice recorder using a mono to stereo 3.5 mm adaptor so I could drive legally and listen to the recordings at home (I could actually also listen live using ear buds hooked to the Olympus if I wanted). I did the same drive 6 times, switching the lead hooked to the recorder each drive. Not as useful, as you can only do one channel at a time, but nice to know you can do it. To be clear, the 6-channel control box and headphones that come with the set work great. My alternate configurations come from me wanting to test drive alone. Headphones are a no-no for drivers here. A word about cell phones: another reviewer mentioned interference from his. Boy was he right! While testing my setup in the truck, I would occasionally hear a specific computer type noise pattern. The pattern would repeat every few minutes. Remembering the reviewers comments, I took my phone and moved it closer to the Chassis Ear control box and it about hurt me ears it got so loud. My Motorola Android definitely caused unwanted interference with my Chassis Ear. No biggie, just be aware. More than two feet apart and no trouble.

Nunca nos llego el pedido. además nos penalizaron con cierta cantidad de lo pagado. ni es justo lo que están haciendo ya que por causas al proveedor no envian lo solicitado y después nos regresan cantidad inferior a lo pagado. me quejare ante las autoridades competentes para que me regresen la cantidad pagada de mas.,

Use this tool in my professional shop. Great for finding those difficult drivetrain noises. I have used the wireless design but prefer the wired model due to the better audio.

This tool is a must if you do any warranty or noise, vibration and suspension work

These are the best on the market. The wired ones are the most reliable
