Bad upper motor bearing. When you remove & replace (or repair) the motor, also replace the motor seal.
FWIW: A new motor is pricey (I’m guessing around $700).
I’m a tech, so I’ll remove the motor, test and inspect it, then replace both bearings. Definitely not a simple task if you’ve never done it before. Tools to do that are a suitable puller set, a hydraulic press, a megger…and some knowledge of what you’re doing.
Another alternative is to take the motor out (mark the wires so you know where they go) and then seek the services of a motor repair shop.
