I'm getting a loud humming noise coming from my 07 Type S 6mt

It sounds a lot like the sound unbalanced or unevenly worn tires would make, BUT I just had that done not long ago, and these 1 year old tires haven't given me any issues before... Although I'm not ruling it out that it could be the tires. I did swap the front and rear wheels just to see if maybe the noise would go away/ be obvious that it moved from the back to the front, but the noise seemed to be the same. I can't really tell where the sound is coming from, but it seems to be from the rear, again, hard to be sure. I have ruled out any engine issue because I turned off the engine while cruising down a hill, and the humming continued.

I spun the wheels on the back when I had the car jacked up, nothing seemed out of the ordinary. I figured I'd put this thread out there just in case anybody else had this issue, but right now I'm just thinking I'll take it in to my local shop and see if they can diagnose me.

 

axles or wheel bearings would be the next thing i check

 

Sounds like a bearing, I had to replace my rear passengers side last year. Does the noise change when you' swerve left or right?

 

I don't think so, no.

It stays pretty steady based on speed.

 

Try being over dramatic on long sweeping swerves. You have to load up the one side pretty good to hear the increase in sound under load. I'm willing to bet its a bad wheel bearing. How many miles on the car?

 

Yeah, I did notice a change in the noise when I did that.... It's got 109K miles

 

Yup, you were right. My local Honda shop is fixing it for about 250, I’m perfectly fine with that
