What kind of noise will you hear with bad right wheel bearing? It sounds like a whirl behind radio and gets louder with increased speed over 35mph.

does it sound like wind blowing like a WOOOOOOOOOO sound?

if so get ur differential checked

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.

wheel bearings most likley im a bit botherd by the "rotated front tyers" bit???

Sounds like one or both of the front wheel bearings are bad. Very common on all GM vehicles. Take to a shop and have inspected. Can you hear it more on one side than the other?

Thats bad, if it really is the trans. When wheels are up in the air, put the car in gear, and grab the coil spring. If a wheel bearing is bad, you will feel the vibrations through the spring. If you compare right and left, you will be able to tell which wheel bearing is bad.

first rotate the tires see if there is a change. If that does not have a desirable effect there may be a worn wheel bearing,take note if the sound or vibration gets louder as you turn a corner, try left turns as well as right turns if the noise increases it is a wheel bearing.

Hello! If the humming noise is speed related(gets louder as vehicle speed increases)check front wheel bearings. If the noise goes away when turning one way or the other then it will most likely be in the front wheel bearing. If you turn the wheel(while moving)to the right and the noise goes away it is on the right side. If you turn the wheel to the left and the noise goes away its on the left side. Hope this information helps!

sounds like a wheel bearing to me..

What kind of noise? Is it a humming noise that gets louder as the road speed increases? If so, it's a wheel bearing - A4s eat wheel bearings like popcorn.

That sounds like a wheel bearing starting to go bad. Usually you'll get a rumbling sound that will increase in volume and sometimes pitch as the speed increases. A quick way to check for wheel bearing wear is to first determine if you hear it at the front or the rear. Once you know that (or at least have an idea which end it's at), see if the noise gets louder or quieter when you turn. If you make a right turn and the noise gets louder, the problem is on the left side of the vehicle, because you're loading the suspension on that side. If you then turn left at speed and the noise goes away or quiets down, you reinforce the fact that it's on the left side because you're unloading the suspension on that side.

When you've determined as best you can which side and which end of the vehicle the noise is on, you'll know which wheel to check. Jack up that corner of the vehicle, and grab the tire at the top and bottom. See if you can get it to move at all by shaking it. A good wheel bearing will allow no play whatsoever. If the bearing is going bad, you may see that you can "shake" the wheel while it's mounted on the hub.

If you have a hard time determining which wheel it is, jack up each corner and shake each wheel in turn and see if any of them shake while mounted on the truck. If you find one that does, you're most likely looking at replacing a wheel bearing.
