Ok here I go again. Yesterday I was on the Highway, and when reaching about 60 mph, a loud (really loud) fast rattling noise appeared like right in front of me in the engine bay. It's A sound like a vibration a bit like when you roll on those stripes they made on the border of the highway that when you leave the road and your tire enter the stripe it makes a loud noise to prevent you from goin asleep (I dont know if you get what I mean). It also sound like when we were young and placed cards in our bycicle's wheels to sound like a motorcycle.
Whenever I get back under 55 mph, the noise stop. I did it a couple of times, and everytime I get over 59, it appears, and disapears under 55. Under that speed, the car doesn't do a single noise and drives normally. What could it be?
