Hello. This can be caused by a few things. I usually check the tires first as any uneven tread can cause a noise like this. If any of the tires are questionable I rotate the tires to see if the noise changes. If it does then I replace the tires. If the tires are fine, then I get the car in the air and spin each tire to listen for the noise. Some of the time, I will even drive the vehicle in the air to see if the noise still occurs.

If it does, then it is coming from the front. If not, then it may be from the rear. If the bearings themselves are fine, then most of the time this is caused by a failure in the output bearing of the transmission. You would then need to have the transmission disassembled and repaired. In some cases, even a bad CV axle can cause this so I check these also. If you need to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the noise.
