Pump going out?

Sounds like the pump may be going out. Nothing visible is loose to cause that sound. Can’t upload video for some reason.

Audible sounds like squealing or even heavy grinding are symptoms of the bearing beginning to wear. In some cases, you might find a local repair shop experienced to inspect such things or replace the bearings. Depending on the age of your pump/motor, it may simply be time to swap it out for a new one.
