A guest case study by Martin Jensen, describing his work on diagnosing a driveline vibration problem on a Lexus.
"My customer bought the car 6 months previously. During the initial test drive, he noticed a slight driveline vibration. The salesman told him it came from the tires. The car got four new tires matched with rims, balanced and road force tested. But the car still had a driveline vibration."
