The grinding /rubbing noise is rhythmic but varies in intensity. Appears to come from the front middle. Grind grind grind with the rotation of the tires. If I slightly turn to the left the noise goes away - turn back to straight and it comes back. Does not appear to correspond with engine rpm, only wheel rpm.
Has gotten significanty worse on the drive home. Started out a week ago only appearing during a hard turn at low speed as a scraping noise (thought maybe the wheel was dragging across a piece of loose wheel well plastic).
Any ideas?
