Vibration Repair Stories

Diagnose and Repair Vehicles that Nobody Else Can!

As an automotive Professor for the last 31 years, I have been involved in diagnosing vibration problems on many “can’t be fixed” vehicles. Each of these vehicles had already been “diagnosed” at repair shops or dealership service departments. Each of these vehicles has had repairs attempted, and many have had parts replaced. Some of these vehicles had even been repurchased from the customer, sold to another customer, or even donated to the school at which I teach to get them off the road.  – John D.
