2002 s80 humming/groaning noise

New to the forums and I'm trying to get some help with a problem my friend's car is having

It's a 2002 Volvo S80 T6 w/ 180k miles on it. From the moment it starts to move, there is an increasing drone/humming/ sound as if metal is being turned on a lathe or something metal is rubbing. It doesn't seem to be coming from the engine but is coming from the front of the car. My friend says that a shop told her it's the tires, but it's definitely NOT the tires. It's more of a mechanical noise. She has had the wheel bearings replaced and actually the sound has gotten a bit worse. Brake pads have been replaced recently as well.

I'm thinking it may be the CV axle or joint turning? I don't think they have ever been replaced. Is there a good way to check this? The shop also told her she needs new shocks/struts, but I don't think this is a related issue.

I have some good general car knowledge as my father was a mechanic for 30 years. The droning sound is loudest at about 30-40 mph and is constant while the car is in motion. At idle tapping the gas, the sound is not created. Thats why I don't think it's engine related. . unless it's the turbos? (This car has a turbo doesn't it?:confused:)

Anyway, please let me know if anybody has any ideas on what to look for. She doesn't have a bunch of ?$$ to spend and I'm trying to help her out.

BTW. . I just picked up an 09 Volvo C30 R-design and am loving it.

Thanks for the help

Welcome and congrats! Have the rotors been replaced?
If you jack up the car and rotate each wheel you may be able to isolate or eliminate various components such as if it is a particular wheel or not coming from the wheel at all.
