Consumer Description

The rear differential started making a loud whining noise around 53,000 miles. It then turned into a grinding noise. I had it checked by a mechanic and he confirmed it was rear differential that needed replacing. He recommended not driving the vehicle since the differential could completely fail and cause an accident. Not having any mechanical experience, the noise was the only indication of a problem. No warning lights or sensor faults.
