This started last week or so. As I am driving I hear this metal on metal sound. I have been driving around listening to it and I have not been able to determine what seems to cause the noise to start.
It will happen most often when I get back on the gas, but not all the time probably around 60% of the time. It will happen at just about any time except when I am cruising down the road at a steady speed.
The noise doesn't stick around long as it comes and goes frequently. it happens often, but in short duration. It is not very loud as I cannot heat it with my windows up.
Any ideas as to what is causing the problem and how to fix it?
