Re: bearings or cv joint?
For quickly ruling out the CV Joint, in a parking lot, turn one way in a sharp circle, then the other way circle sharply. A clicking sound is indicative of a bad c/v joint or 1/2 shaft.
Humming while in motion (most of times it will only occur during a specific speed range - over a certain speed goes away) says a wheel bearing is shot.
Normally you should replace both at the same time... however you can check with a laser temp gauge each front hub after driving. The hotter one is bad - or a less scientific approach is to swerve going down the road. and listen for an decrease in noise going in one diretcion over the other.
If you are turning the steering wheel right, and the noise goes away, the right bearing is bad and vice versa.

have a friend drive slow as needed on a flat quiet road , stick your head out the window try to better locate the source of sound , can be anything ranging from bee's nesting in the ac ducts to a bad cv joint in driveline
ITS PROBABLY TOUR WHEEL BEARING . IF YOUR GOING DOWN THE ROAD AND THE LONGER YOU DRIVE THE LOUDER IT GETS. OR IF YOU TAKE YOUR WHEEL AND GO BACK AND FORTH A LITTLE WHILE MOVING AND THE NOISE COMES AND GOES ITS PROBABLY A BEARING . A CV JOINT WILL POP WHEN TURNING HARD AND ACCELERATING . THIS BEARING PRESSES IN WITH THE HUB ITS A PRETTY DIFFICULT JOB IF YOUR NOT A TECHNICIAN WELL GOOD LUCK
Noises from axles can be really deceiving. The sound is transfered throuh the transaxle and can resonate through the entire vehicle. The turning to the left thing makes it sound like a problem in the right wheel/axle area. Wheel bearings and axles tend to make worse noise when they are on the OUTSIDE of the turn. More of the vehicle weight is shifted to the outside due to centrifugal force. Thus, if the noise is louder when turning left, this puts the right axle to the outside of the turn and the most likely to be the source of the noise. (and vise-versa) The fact that the noise calms down while cruising makes me believe that it is not a wheel bearing. Wheel bearings can make more noise in turns, however, they usually make a "roaring" or loud "humming" noise that gets louder with speed. An axle is more likely to change or get louder according to engine load more than rotational speed. (Way worse while accelerating or climbing a hill) I would be taking a hard look at the right axle.
Often, that sort of humming is a wheel bearing. Since you have newer tires, and the noise gets louder when you steer, it could also be your CV joints, but the wheel bearing is the most likely suspect.
Most likely it is the RH front wheel bearings. CV Joints don't usually make any noise until you turn a rather sharp corner. I would advise you to replace the bearings and seals in both front wheels if the bearings are in fact noisy. Jack up the front and spin each wheel, you'll soon hear the sound of rumbling bearings.
Does it happen turning in both direrctions? It could be cv joints. from a standstill,turn the wheel hard to the right and accelerate in a circle. do the same on a left turn. If you hear a clicking sound, it's bad cv joints. inspect the rubber boot for tears & stress cracks. once the grease escapes,the joint is no good
If the sound is all the time, no matter what you are doing then it is the Transmission going bad. CV Joints, Wheel bearing will only make the noise when in rotation.. Also remember that this is a front wheel drive car, so it will throw you off thinking it is the wheel bearings or CV joints due to the front wheel drive
