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.

It sounds kind of like a bearing. Maybe from the top metal gear. Spray some lithium lube into the bearing?
