Ok guys (attention Chris!) -
I'm going to set the scene for a troubleshooting task.
Engine is running, car is moving slowly down a driveway and when it came to the end of the driveway, with the smallest of drop between the end of the driveway and the road, a sudden metallic sounding "thud", short and sharp (refer to video link below)
Later that day, I also heard the same sound when reversing out of a parking spot and turning the steering.
Watch the attached video and listen carefully. Interesting to note how quiet my exhaust is and how loud the noise is...
Please let me know what you think it might be??
