“The vehicle is driven exclusively by my wife. She complained to me of a rumbling noise when turning the steering wheel. I investigated. I drove the car up & down our street and confirmed the noise. Whilst someone was turning the wheel back & forth while the vehicle was parked, I followed the noise to its source. I discovered that the left front apron had broken loose from the frame and was making contact with the steering shaft. A further look showed that where the seams of the apron and rails structures were rotted apart where they met. …”
