Recently, my younger brother with a 2012 Subaru Impreza sedan (GJ chassis) and 5MT has had a wheel bearing-like noise from his rear end. He got his rear differential fluid changed, and his had significantly-darkened gear oil and quite a few shavings found. Hopefully after the fluid change, it will quiet down.
Despite over 103,000 miles of harsh driving, my wheel bearings are showing no signs of failure so far.
