So the 410 I've owned has gotten louder and louder since the day I've owned it, not wanting to run it into the ground by listening to it "howl" for the rest of it's life. I decided to disassemble it, my guess is it needs new grease and motor bearings.
I've removed the knife bearing hub, and removed all of the lower motor housing bolts
I'll add photos soon.
