I know there are many sounds and noise that comes from a 15 year old car. This sound is a new one that just started. It only occurs from impact on the driver front wheel - bump or pothole (small ones). Sounds like loose metal component rattle - almost as if the spring is loose. I checked the springs loaded and unloaded and it does not move. The thrust arms & lower control arms were just done 6 months ago. So do worn struct bearing make this kind of noise?
