Fiat Wheel Bearing Failure Analysis
This 2014 Fiat Abarth was brought in with the customer being concerned about a noise coming from the left rear. He was convinced that it was a tire. The noise was cyclical and it increased with speed. During inspection, the bearing had no detectable play, the tires were evenly worn, and no ABS wheel speed sensor codes were present. On the lift, the left bearing was significantly noisier than the right bearing when turned by hand. But, no extra play could be detected.
