Hello everyone,
First time post, and very recent lurker. Been having this issue for a few weeks now, and haven't been able to find a solution in the forums for this particular noise. I have a 2009 civic lx with just over 88k on the odometer, but it makes a strange noise only when going at highway speeds. For additional context, I've attached a clip from today to show what im talking about. The noise sounds like its coming from the driver front wheel area, but its difficult to determine precisely where (strut top, lower bushing, sway bar bushing, etc).


I'm new to hondas in general, but I'm fairly certain this isn't a wheel bearing issue, as it does not hum and/or build up from a slower speed. I checked the wheel liners, but that also does not seem to be the issue. I'm a bit stuck and would like to hear what your thoughts are as to what may be causing this issue. Thank you in advance

 

Have you looked under the hood and see any abnormalities?

 

Yes I have. I examined the heat shieds off the manifold and cat, as well as the heat shields going down the exhaust pipe as it travels towards the back and they are not rattling or moving any. I read somewhere that the welds on the exhaust pipe portion of the shields may fail and cause rattling, but in observing them they are perfectly fine. I'm not really sure what else could be causing that noise :-/
