NVH App Helps Automotive Mechanic Shops Solve Noise Vibration Harshness Issues

Your reputation with your customers and with local dealerships must stay on the positive end for your repair shop to survive.

Providing accurate and timely solutions for your customer’s repair needs can be aggravating because there can be so many things that go wrong with today’s vehicles.

Have you had too many comebacks because of vibration issues? Have your technicians advised you not to take specific problems, like vibrations, because it is time-consuming to find the solution?

What if, when you know there is a vibration issue with a vehicle, you could quickly and accurately pinpoint the parts of the truck or car that you need to look at? What if the correct solution to repair the vibration issue and the instructions on how to fix it are available in the palm of your hand? Sound like a sci-fi pipe dream?

What if there was an app that could not only test vibrations,

but also tell you where it is coming from AND give me solutions as to HOW to fix almost any car or truck?

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
