LDO Orbiter V2 started making a weird noise

Recently my extruder started making a weird noise every now and then. It seems to do it for a few minutes then stop. I have no idea what's causing it, but it seems to go away if I remove the filament. I've included a short clip of the noise I've already broken down the extruder and all the bearings seem to be in good shape and there's no obvious debris inside the gearbox.

This only started happening after a couple hundred hours of printing with zero issues.

There's also some oil/grease and metal shavings below where the extruder was mounted, which seem to have come from the extruder.
