My Stealthburner started making a grinding sound when extruding. It's not the motor, but the gear attached to it. I cannot figure out how to stop it though. I've tried reseating it, adjusting the locking nut on the shaft, tightening, loosening. I'm hoping someone has an idea for me.

Defintiely sounds like a bearing issue, but also check for metal filings between the gear teeth - they can accumulate over time and cause that exact grinding noise even if the bearing seems fine.
