Posting for some help diagnosing what I believe could be a wheel bearing going bad. However, it doesn't sound like other wheel bearings I've had fail on other vehicles before so looking for some confirmation.
The noise sounds like a higher pitch scraping/squealing noise coming from my driver side rear wheel. It varies with wheel speed and does not change under braking. The noise goes away during left-hand turns.
I initially thought it could be something scraping against the rotor, but took the pads out and took a close look and couldn't find anything. Not completely eliminating that possibility, but I couldn't diagnose it myself.
See
a video of me spinning the wheel while the pads were removed from the caliper. Any ideas?
