Powersteering pump

I've been having a squeal from under the hood like a bearing is bad. It started off hardly ever doing it and now it squeals 60% of the time. I took the belt off and spun all pulleys, they all spun freely except the powersteering pump. My question is should it have tension on it or spin freely?

It is a pump and will have some drag when spinning it.
If you have a squeal I would suspect that your belt(s) may be worn or loose.
If you have a whine, then it is likely the power steering pump is failing.

The belt is new and believe me I know what a bad bearing sounds like from a previous situation. Every time I pull somewhere so I can pop the hood to try and hear the general area it's coming from, it is stopped already.

I have had new belts squeal too.
Turned ot that my alternator pulley was worn out.
Maybe try putting a bit of belt dressing on the belt to see if the noise goes away?

It's not a belt squeal, it's a bearing. Not sure which one yet other than the power steering pump turning with resistance. New pump is $40 just didn't want to replace it and it not be that.

Water pump, alternator or smog pump bearing?

Can you take a long screwdriver and carefully use it to "listen" to the pump?
Sometimes that can help you pinpoint the problem.
