My X has been whining since the day I bought it, which was August of last year. I thought all along that it was the notorious power steering pump whine that so many Fords suffer from. A month or so ago, I decided it was annoying enough that I would try to get rid of it. I stethoscoped the p/s pump, but the noise didn't seem to be coming from there. In fact, it seemed as if it was coming from the opposite side of the engine. At that time, I stethoscoped the alternator and was sure the bearing was bad because even the stethoscope vibrated significantly when I touched the alternator. I replaced the alternator with a new one and the problem was still there. I swapped my old one back on and got a refund. At that point, I thought it might be one of the idler pulleys below the alternator, but it was getting dark and the next few days brought foul weather. I got out of the mood to work on it until today. I thought I would take an exhaust video and when I put the video on my computer, I could hear the whine over the exhaust. I took a second video under the hood and in the video, it appears that now the sound comes from the driver's side of the engine. The next step is to remove the belt and see if the sound disappears, but I thought I would seek advice here on the forum since I'm sure someone will know exactly what the problem is. Anyway, here are the videos.
