Humming sound remains

Got a humming sound that goes away when turning right. It's loudest around 50 mph.
Changed front right hub assembly. Sound still remains.

Did I change the wrong side? Tips please!

I could be the other hub. I've had hubs get quieter when loaded more. Could be tires too, and rotating them side-side might help isolate that.

It could be a rear axle bearing also .

I'm guessing it's the front by where the sound comes from. But if I can't find it i'll look at the rear.

I'll also swap tire first to confirm.

So changing the front tires didn't solve the issue. I was pretty certain that it was the other bearing. I used the replaced hub bearing to replace the bad one, if that makes sense. The noise is gone!

Feed forward: the humming noise went away when steering to the right. The left wheel bearing was the bad one.
