Long story made short. Hit a piece of concrete that came out of a pothole at around 50kmh, was bad enough to bend my rim. Got the rim fixed by an expert wheel repairer.
Put all the wheels back on, did balancing and alignment, then started noticing a weird low pitch humming/whirring noise coming from the front of the car. I'm assuming from the wheels.
The noise only becomes loud enough when hitting 70-80kmh and then goes away and then comes back a bit louder at 110-120kmh. Very weird.
How do I tell what it is? So far, I've been advised it could just be tyre noise, but thats weird cause it only started after the incident.
Some say it might be the hub or wheel bearing. I am taking into a Volvo specialist next week, but thought I could try gather and diagnose as much info as I can before then.
Anyone had similar issues maybe?

It really needs a proper visual and physical investigation to determine the cause, anything else would just be speculation. Did you have a new tyre fitted after the incident? Any impact severe enough to damage the wheel may have resulted in internal damage to the tyre structure which would be impossible to see by a visual check alone, and could result in a catastrophic failure at some future time.

I had a simular noise from the rear wheels my tyres were out of round when I I had it investigated replacing the tyres fixed the noise
