Soft thumping noise towards the front of vehicle, it gets worse and faster the faster the vehicle goes

Faster speeds make the dash squeak. It almost feels like a wheel/tire is way out of balance, however You can barely feel it in the steering wheel. There is no change when brakes are applied. The front brake pads are getting worn and in need of replacement. Sometimes while driving at highway speeds, the noise and vibration goes completely away when you turn the steering wheel slightly, such as switching lanes or going around a slight curve. The front tires have been replaced, wheel/tires have been replaced. There was no change after this. Also the bearings, ball joints and everything else seems to be okay. However I'm not real sure about the CV axle shafts and/or joints.
