Recently my 2007 Legacy sedan has developed a noise which I'm sure is not engine noise. It's a 2.5i with manual transmission and 36,500 miles on it.
The noise is speed related - starts getting really noticeable at 50 mph and louder the faster I go. The tires are original and look good - still a lot of tread before it gets to the wear markers. All the fluids are OK.
I've read about the wheel bearing problems in the older models, but I thought it was fixed in the newer ones. Anybody got any ideas?
