My 2004 Expedition 5.4L2 has had a whining sound that rises with acceleration and stops when I take my foot off the pedal. When I start accelerating again, it starts again. This is my second Expedition and I noticed a similar sound with a 2000 model. It's not the tires, as replacing them hasn't caused any change. It seems a bit louder on the driver side. It's not a high pitched squeal, more like a consistent higher pitched moan. It is very consistent, not up and down (unless I take my foot of the accelerator. Any ideas?
