Why would a 04 Grand Prix make a humming noise that gets worse turning right?

Its probably a wheel bearing but check your tyrod ends as well. Sounds like the power steering pump is bad (common on these cars) check the power steering fluid level (make sure the engine is cool to the touch first and be careful not to spill any as power steering fluid is very flamable.
