Default Strange noise idling, revving engine, and driving

Higher speeds like 30+ the sound is mostly gone. As you accelerate to 10+ the noise gets quieter. Even with windows down. I had a/c and heat off, and still made noise. Not sure what the noise could be.

Here is a video. Sorry about the beginning. Didn't realise the camera was blocked.

That sounds like you shouldn't drive it anymore because you can damage it or cause more damage. Take it to a mechanic.

I like diagnosing, and fixing stuff myself. I am going to do some troubleshooting. I believe it's a pulley. I replaced the power steering pump, belt, and tensioner 4 years ago. About 20,000 miles ago. I know the power steering pump could've failed. Going to check all that out. I was doing more research while waiting for a response here to see if anybody had any details to help. I appreciate your response though.

What if you try a diagnostic tool?

Power steering fluid was at the min level when the engine was warm. So I added some. I loosened the belt, and moved the pulleys. They seemed fine.

Found another test i'll try tomorrow. It sounds like it could be the alternator bearings.

Im thinking alternator, power steering pump or water pump. A automotive stethoscope will help you pin point the source.

It is the Alternator. Unplugged the alternator, and started the car. No noise. Revved it, and no noise.

Got the new alternator, and almost had it installed. Ended up snapping the lower bolt in half. Now waiting on a new bolt. $15.00 for a bolt is crazy.

Sound is gone now. How long do the water pumps typically last? I think I am on the original at 110,000 miles. Also what part number? I only found some for the timing. Not the serpentine belt. Just so I have a part reference for future.
