Hi All,
I have a 2014 Forester with ~135k miles on it. I have noticed a humming coming from somewhere at highway speeds.
I just replaced a bad tire (it had thrown a belt), that I thought may be contributing to the noise, but the hum continues. Its pitch is related to road speed (not engine speed), and doesn't seem to change much when turning.
I think I may have a hub bearing going out, but how can I find which one? I have not (yet) put it on jacks to see if I can tell by wiggling. It is difficult to ascertain where the hum is coming from while driving.
Sincerely, Duane
