HD Truck Support
  • Quick, Accurate, and Precise: The app can be set up and ready to begin diagnosis in as little as 30 seconds!
  • Live Results: Watch what is happening as the vehicle is being tested
  • Record while you drive: Record your road test and watch it again in real-time, or pause and go through it step by step.
  • Automatic Diagnostics: Analyzes the road test recording and determine the type of vibration on your vehicle.
  • Totals: Displays the statistics for each type of vibration detected and will break it down by vehicle speed to give you even more information.
  • Share: Email your recordings to another app user (Apple or Android), so they can view your road test results.

This is an easy to use, accurate program for isolating vibrations. You’re up and running in 5 minutes. As a service professional, it saves time and the results are easy to understand. I’ve used other devices that require complicated setup and calibrations. That is not this program.

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
