With the belt off, spin every pulley and listen for a grinding noise. As you spin the pulley it may feel rough and gritty as well. If it does, replace the bearing/pulley.

I removed the belt and it's still squealing. It only does when driving. I replaced the water pump, belt, and I took the belt off and Crunk it. It still seals when accelerating
