Provided the bearing isn't seized, yes, the impellor would still spin. The mere fact the impellor spins doesn't necessarily mean the bearing is still good however.

Okay, I took it out because I did a coolant flush and change thermostat, hot air wasn’t coming out of heater. And the day after I fixed it I started it up and I made that mild squeal, so when I took the water pump out and spun the front and the blades still spun, got me thinking that I took it out for no reason, or maybe I tightened the S belt on too tight?
But the fact that the blades would still spin even if the bearing are bad makes me feel a little better pulling everything out!

Quite often a squeal after doing cooling system maintenance is from coolant that has gotten on the belt and/or pullies. If the squeal doesn't stop after the first few seconds of running, try rinsing the belt and pullies with water and check your belt tension to make sure it's not too loose.
