If you remove the belt, spin all pulleys by hand, any that have a roughness or are hard to spin, replace, the three usual suspects are idler, tensioner, and A/C, Idler and tensioner are held by one bolt, then pull off, install is the reverse of removal! The other is the alternator, if it has a roughness, replace the whole thing, that's due to bad bearings inside it!
