what makes a rattling sound like thin metal hitting thin metal.
it occurs when vehicle is parked and engine running. Unable to check when vehicle is in motion. all fluids look normal.
the sound increases in frequency with an increase in engine rpm but it only increases slightly.
the sound appears to be emanating from the transmission area. It cannot be heard when standing in front of the engine. The sound is identical when your ear is a foot aft of the front wheel on the left or right side.
I’ve checked for anything loose under the body but found nothing.
I have one possible guess,
what is yours?
