Test Your Own Vehicle

Have you been frustrated when you know something is wrong with your car or truck, but your dealership or mechanic never seems to solve the issue fully?

Have you had your wheels balanced over and over, but your car or truck is still shaking?

Has your dealer or mechanic recommended and had you replace expensive parts, but nothing seems to work?

Are you worried about the value of your vehicle or, even worse, the safety of yourself and your family?

Actual defects in parts may cause vibrations in your vehicle, a deterioration that may lead to expensive replacements, or even warranty issues that may cause you to end up driving a worthless vehicle.

Ask your dealership or shop if they can test the vibration in your car or truck with the NVH app.

Just as your cell phone can detect your location and speed, with our app measuring your vehicle, your mechanic or dealer will be able to not only pinpoint the location and parts to be fixed but tell them how to fix the issues.

If you are a semi-truck driver or own a fleet of vehicles, you can use NVH yourself to test the condition of your fleet and make sure no impending expensive repairs are coming.


As a Master Certified Chrysler Technician and a Master ASE Certified Technician I have found the NVH App very helpful with the diagnosis of vibration issues on problematic vehicles. This new software has allowed me to accurately diagnose vibration issues on brand new vehicles, verify tire vibration verses driveline or axle problems and to provide proof of tire and alignment issues to customers and manufacture warranties. This is absolutely the best vibration analyzing tool to date!

Our app will work even if you own a 1965 Ford Mustang or a new 2018 BMW!

What the app can do

The NVH app is designed to automatically detect the type of vibration your vehicle is experiencing, provided the instructions of the road test procedure are followed.

There are 14 types of vibrations the NVH app can automatically detect:

  • Tire speed-related (1st, 2nd, and 3rd order vibrations)
  • Driveshaft speed-related (1st, 2nd, and 3rd order vibrations)
  • Engine speed-related (0.5, 1st, 2nd, 3rd, 4th, 5th, and 6th order vibrations)
  • Electric Motor Speed Related (1st order vibrations)

Each type of vibration has unique causes. A vibration type is not the same thing as a vibration source. There are many possible causes (sources) for each vibration type. The NVH app includes step-by-step instructions on locating the vibration source once the app has identified the type of vibration.

What the app cannot do

  •  The NVH App cannot automatically tell you the source of a vibration
  • Although the NVH app is excellent at identifying the type of vibration your vehicle is experiencing, you or someone else will need to follow the diagnostic steps described in the app help files to identify the exact cause or source of the vibration.

There are almost 300 possible sources of vibration concerns in today’s vehicles
