Hello everyone. I have a 2002 Mercury Cougar, 2.5L V6, 184,643 miles. When accelerating, particularly above 2000 RPM, there is a strange clicking/pecking sound coming from the front end of the car and I absolutely can't figure it out. If the car is in park, you can goose it and it never makes the sound. If you jack it up to let the wheels spin freely then it doesn't make the sound. To be honest, to me, it sounds sorta like one of those toys you put on you bike as a kid that flicked in the spokes to simulate a motor sound? Anyway, here's a video where you can hear it. Please, if you can, help me resolve this.
