What is causing this noise? (Video)

Hey Nation,
My car is making this thumping noise when I'm driving. It's always there when I'm driving and it's consistent with revolutions. The faster I go, the faster it gets. It sounds like it's coming from the drivers side. I don't hear the noise in idle. When I'm driving and turn the wheel slightly to my left, I do not hear it. Any ideas what it could be? Thanks in advance!

If it doesn't make this noise while at idling, then you can rule out any possibility of a bad bearing or pulley on either your alternator, or AC compressor. My car made that same noise(sounds like a washing machine) and it ended up being a bad AC compressor.

Now if this only makes the noise under driving conditions it almost sounds like a bad wheel bearing. One way you can check is by grabbing the wheel and tugging it back and forth towards you. If you hear clunking or if there is and play between the wheel and the hub, then it's a bad wheel bearing.

Also check if the noise increases under braking, incase if it's relative to any brake problems. Almost sounds like a bad wheel bearing.
