Ever since Ive had my Edge and my 35's every once In a while I get a vibration through the accelerator pedal. It only will do it when the truck is in overdrive with light engine load going from 55-65mph. Im not to worried about it I just wanted to know what this could be? It doesnt do it but every once and a while. I can also feel my windshield washers when they move I feel them in the pedal also. Is all this normal or not? Thanks

 

I recall seeing some old threads covering this topic. I'll try to find them.
