Steelman Wireless ChassisEAR Vehicle Noise Diagnostic Kit — 4 Transmitters, 50 ft Range, Magnetic Clips

The Steelman Wireless ChassisEAR is a four-transmitter wireless diagnostic kit that helps you locate squeaks, rattles, and other vehicle noises up to 50 feet away.

If you’ve ever driven a vehicle with an intermittent noise that disappears when the car is lifted or a sound that’s impossible to recreate in the shop, this kit lets you listen while the vehicle is operating. The system pairs four independent wireless transmitters to a single receiver so you can monitor several points at once, isolate the offending area, and confirm whether the noise originates from suspension, drivetrain, engine mounts, or body panels.

How does the ChassisEAR find noises I can’t hear from the driver’s seat?

The transmitters act like remote stethoscopes: attach them to suspect components and the receiver plays back what each unit senses. Because you can listen while the vehicle is running under normal conditions, the kit reveals noises that vanish when the vehicle is stationary or raised.

• Four transmitters for multiple simultaneous monitoring points
• Magnets, clips and nylon straps for secure attachment
• Built-in speaker plus 3.5mm headphone jack for private listening
• LED signal indicators to gauge transmitter strength

What range and compatibility can I expect for different vehicles?

Each transmitter communicates with the receiver up to about 50 feet, giving enough distance for small cars and most light trucks as well as many larger vehicles. The wireless units use newer frequencies, so they won’t pair with older Steelman 60635 or 97202 models.

• Approximately 50-foot transmitter-to-receiver range
• Suitable for cars, light trucks, and many larger vehicles
• Not compatible with older Steelman 60635/97202 systems
• Includes batteries and storage case for mobile use

How do I operate and interpret the receiver controls?

The receiver assigns one channel per transmitter and shows signal strength with LEDs so you can compare sources. Channels light when active and can be muted or switched quickly, letting you single out one transmitter while excluding others for clearer diagnosis.

• Illuminated channel buttons for easy selection or mute
• Signal strength LEDs for quick directional clues
• Headphone jack for focused listening during tests
• Simple push-button switching—no complex menus

What accessories come with the kit and how do they help?

The kit is supplied with a comprehensive set of mounting options and power so you can deploy it immediately and keep your work area organized. Multiple straps and clips make it simple to affix transmitters to irregular surfaces or rotating components while the blow-molded case stores everything between jobs.

• 4 transmitters, 1 receiver, and mini earphones included
• Magnets, clips, cable leads, and 12 nylon and hook-and-loop straps
• 6 AA and 16 AAA batteries provided for instant use
• Organizer pouch, location pad, instructions, and hard case

Who is this for? The Steelman Wireless ChassisEAR is built for professional mechanics, mobile technicians, and serious DIYers who need to troubleshoot intermittent or elusive sounds on engines, suspensions, transmissions, axles, and body mounts. It’s especially useful for technicians who diagnose noises that only appear under load or during road tests and for anyone who needs a portable, multi-point listening solution without tangled wiring.
