diagnosing noises is the hardest to do on the internet. My #1 bet is that it's your tires. When you said you didn't

Less than 20k miles on the tires. From Discount Tire, nothing special

That's about the time they wear in and start making noises.

So it could be nothing? That's not my favorite answer but it's better than

You should hear my lexus. It grinds like mad between 35-45, then it goes away. Wheel bearings check out, suspension is

My tires hum like crazy at certain speeds. I’m going to get MT’s next, can’t

And if the MTs are too quiet for you, throw on a roof rack!

Rear axel was replaced about a year ago so I sure hope it's not the diff

I'd definitely check into the wheel bearings then. I had that issue on one of

I haven't tried rolling down a hill in neutral to see if the noise is still

Looks into the IWE and hub vacuum. They are known to make a high pitch whining

Mine has manual locking hubs. So IWE isn't applicable right?

Check 12 and 6 too. 3 and 9 play can also be steering linkage

When the sound is happening and you lightly apply the brakes at 30+MPH does the sound stop?
