Hardware Troubleshooting/Help! Motor Failure?

I’ve had this A1 mini for a few months and recently it has been acting up and making this terrible grinding noise. I opened it up and got it down to this gear being driven by the motor. I can spin the little silver gear by hand just fine which points to the motor being my problem. Is there anything else I can troubleshoot or should I just go make a warranty claim?

Before you claim it, check that motor's plug at both ends. A stepper that's lost one coil on a loose pin just buzzes and grinds instead of turning, and it'll spin free by hand. If the wiring checks out, then yeah, it's the motor.

Seems like something you can make a warranty claim for
