Austinite

so the handwheel on my Janome has a little squeak. It only happens when I turn it towards me. I've checked everything else, I'm rather obsessive about cleaning my machine so there's no lint in the bobbin race, walking foot is nice & quiet, all the other moving bits I can see look well-lubed, fresh needle, rethreaded bobbin and upper thread a few times, checked the manual which was no help....anything else anyone can think of? Other than the little squeak it's sewing beautifully. the sound just makes me want to scream...

thanks in advance to anyone listening!! i'm totally in the mood for late-night sewing!!
