Hello I have a 2014 ford escape 2.0 titanium and when i accelerate i hear a thumping sound i go fast and it gets louder. The car runs great i let go of the steering wheel and she runs straight. I do not hear any metal grinding noises it sounds like a helicopter i have new continental tires well a year old no uneven wear pattern that i can see. When i run on the concrete highway it quiets down a little bit. Can someone help me please
