could be the tensioner pully or idler pulley. 1 bolt thru the middle, easy to replace and around $15. bearings are sealed and wear out abot 100k. both are the same pulley just a different spot. one is spring tensioned the other is fixed to a bracket

my 10cents worth maybe only worth a nickel on this subject but here it is anyway!! lol
My 93 ford supercab has a long history of the "squeaks"....numerous belts, idler pulley...tension pulley...belt dressing..etc etc..been there done that...Here are my ideas.
1: replace the tension pulley and new belt at same time if you have more then 50k on belt etc..while your replacing, take fine emory cloth/sand paper and clean surfaces on idler pulley, fan pulley and any other pulley/belt surface you can get too.
This should take care of the squeaks at idle (usually more noticable if air is on or fan is on). Tension pulley is easy to take off, reverse threads like previous poster indicated, once youve taken the belt off once,and figured out how to put it back on, trust me, you become a expert at it over time with these trucks..
i DO NOT recommend belt dressing, although it may have worked fine on my wifes old 83 Buick Century which had numerous belts,,,all it did was INCREASE the squeal on the serpentine belt of my Ford Pickup...
Anyway, good luck, from all the posts in the past, this is a very common problem with ford pu's...it sure is with mine ( i have 2 belts hangin in the garage with less then 10k miles on each) If you do just replace the belt, it will usually clear up the problem for a short time but its just teasin ya...the problem will return within a few thousand miles,,,clean those pulleys,,,replace the tensioner,,,,that should do it.....PS> search this forum for previous posts on the subject...its filled with them!!..

While you have that belt off,work the tensioner back and forth through its travel range to loosen it up.If you can get to it,shoot a little oil on the pivot.When you slip the belt back on,push the tensioner to help it take up the slack.If the tensioner is weak,the power steering makes a noise all the time.If your high mileage,that alternator bearing gets loud,too!
