    Just wondering if it's possible for the bearings to go out on one of the pulleys. I think from my little mudding trip one of the pulleys are shot. The trucks idles, runs like there is nothing wrong. Truck runs great, but I hear this kind of hissing/ or like the sound of ungreased bearings rolling around when I accelerate. Any ideas?

    yeah probably your idler pulley since the bearing is somewhat exposed.

    Yea see like on the interstate between the radio and the humming of the tires you can't even hear it. I floored it last night and it took off like there's nothing wrong do I figure that dirty water got in there and wore the bearings out. Think I will be on driving home 6 hours on it. Any idea what those things cost. I was thinking like 100buxs
