Automotive Chassis Ear

[Stevewr54]

Does anyone own a chassis ear that really works? I have a Steelman that had issues and was graciously replaced with the help of a GJ member. The new
one has one channel that sort of works but not well. I'm open to suggestion because these wheel bearing noises are driving me nuts. Thanks in advance, Steve

Worth doing some research to see what's possible

Are you talking about the wireless version, or the wired version?

I have the steelman wireless version and it does work.... but the receiver can pickup a lot of static and noise which makes it hard to listen to the actual sound being transmitted. Also, the batteries that came with my kit leaked battery acid all over the place and now two of my transmitters do not work at all because of major acid damage. At one point someone on this site contacted me about the issues I was having with my wireless chassis ear.... Of course I forgot to reply and then when I remembered, it was way too late. (I posted a comment several years back about the trouble I was having in another chassis ear thread) I see they now have a completely new re-designed system with new transmitters and new receivers but I don't know how well they work.

That gives me an option. Thanks

I purchased the chassis ear replacement wired leads, and soldered banana jacks onto them. There are now adapters, I beleieve jarhead diagnostics sells which makes this easier. Anyways this allows me to plug them into an oscilloscope and see the data that way.

The replacement leads cost $60 or so for a set. Because of my solder job they have slightly different responses to background noise, so their 0v output is varying in how much noise is on the channel. I would buy the adapters if available.

I have never used a traditional chassis ear setup with headphones. Wheel bearings I typically find spinning the wheel while holding the spring, or having someone drive the car a 20mph on a rack. The latter can be tough with traction control aids.

Thanks for the heads up on Jarhead. Good stuff!

They make a lot of cool items, worth scrolling through their page.
