Proud owner of a 2010 Hybrid with 125,000 well maintained miles. The right side started Humming or Roaring quietly as first, but has increased in volume. Having driven this car alot LOL, I am used to every noise it makes. I have noticed that when turning left the hum stops and when turning right it continues and almost increases. Lug nuts don't seem to be loose. It almost sounds like a bearing. Any suggestions?
