I have had my Explorer serpentine on for a while and everything works great except I have a squeak that I can't locate. I replaced all of the pulley bearings and the squeak did not go away. I thought it was coming from the lower idler pulley and replaced that bearing a second time. I used some WD40 on the pulleys and the sound goes away for a short time. The problem is that it does not matter which pulley I spray. The lube is being carried by the belt to all of the pulleys. If I spray the belt itself, it gets very quiet. It sounds like the fan slows down. So I'm wondering if the noise could be from the fan clutch? Maybe from the water pump?
