1996 ford explorer squealing

I have a 96 explorer AWD 5.0, it started squealing out of the blue so i changed the serpentine belt and the belt tensioner pully. Now it still squeals not near as bad more like a humming sound what else could it be

Check for an idler pulley (simple pulley between accessories that assists the routing of the belt over the other pulleys); their bearings go bad about as often as the tensioner. Also, if you didn't do it already, start it up with the belt off to confirm it's an accessory/belt noise and not something internal. Also ensure power steering reservoir is topped off and try listening with the ac on and off.

I found this to be easier than removing the belt to prove the noise is coming from belt or pulleys. Shoot some baby powder on belt when running. This will stop noise for a while.
