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?
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
