Loud whining sound
Loud whining sound seems to coming from the back of my car. Start hearing it at about 30mph up to about 60mph. It may be at higher speeds too, not sure if it’s road noise covering it or that it’s not as loud. Best description is like when Honda civics are retrofitted with a muffler that makes a really annoying high pitch sound. Only mine is heard in the car. Not sure if it’s heard outside car. Thank you
