Constant belt squeel, shredding belts, need help please!

i have a 2000 7.3 f250, when getting it on the road (august) the belt was squeeling so we replaced idler bearings, cleaned pulleys and replaced belt, within 3 days of getting it on the road it shredded a strand off the belt and left pieces scattered about the engine bay. got the belt replaced, within another couple days it did the same thing. so i left the belt like that, with a strand ripped off all the way around. it didnt shred it any further, but it was constantly squeeling, so i got some lithium grease spray (i believe it was) and sprayed my belt, as soon as i sprayed the side with the tread or whatever its actually called the squeeling stopped. so for a while now ive just been spraying it to shut it up. put my original belt back on today because it wasnt shredded so i wanted to see if it made a difference. this one actually squeels worse. so my question is why am i constantly shredding belts? ill keep an eye on this belt to see if it shreds, but spraying it only shuts it up for a few seconds...
thanks guys

I'll bet its a misaligned pulley. Look at the front of the motor from the side and see if you can see a pulley that is a bit forward or back from the rest. My power steering pulley was pushed in just enough to make that squealing so I pulled it out about 1/8"

I just went through the exact thing on an 01. Couldnt find anything loose or binding.Tensionor was tight and not loose but after closer look it was tilted less then an 1/8'' but was enough to cause it to ride up on AC pulley and shred the fornt of the belt. And it had an annoying squeel. Replaced whole tensionor for $65 all is good now

thanks for the reply man. I'll look into it on the weekend. Was there anyway to adjust the tensioner back or does it need to be replaced

u just replace.2 bolts holding it in real easy. Take it off and look at the area where the 2 pieces meet and look for a small gap on one or the other.it doesnt take much to throw it off.
