Here a video i took of it after i noticed the noise. Sorry for the bad filming. Its the whinnying you can hear after a little rev.

 

Does it go away with your radio turned off? Mine whines like crazy through my speakers. I apparently have a loose ground somewhere.

 

Sounds like power steering or alternator. Check power sterring flui level

 

Check if he noise increase when you push the brake until the end on Parking, if is do it is the brake booster, probably liquid level is low

 

That's on hydroboost vehicles. Not vacuum boost. Unless his cobra is hydroboosted.. I can't remember.

 

It does get louder when braking

 

I did notice it seems harder to steer too I'll check it out

 

You most likely have a hydro boost style brake system and your powersteering pump is going out causing you to hear it when you apply the brakes. You will need a new power steering pump most likely.

 

Oddly everything seems to be working just fine today!

 

I had same issue, this came after repair a steering wheel leak. the mechanic said that it would be decreasing, so it did it but i can’t notice how harder was the noise before the steering wheels hose replacement

 

Steering wheel leak??? What's that??? Does it have to do with the blinker fluid tank?

 

I was talking about a leak in to one of the hoses in the steering wheel system.

 

Sounds like power steering pump!

 

Hate to be that guy that brings these oldish threads back.
But almost four months since I noticed this and finally got around to getting it fixed.

Power steering flush was all I needed.

Everything is running back to normal now.

 

Is ok to woke up old threats, some times there are threads with Unsolved issues, good to know what fixes yours

 

Flushes tend to be a temporary fix because the old fluid already caused some damage. Most cases anyways. I would keep an eye out as you may still have an issue.

 

Will do. I hope it is fixed however.

 

Sounds exactly the same as when one of my pulleys was bad (bad bearing)

 

Check the power steering. That sounds like the pump not getting enough or low on fluid

 

Once again tbone is right. The whining noise came back last night. It was a temporary fix. I haven't noticed any machincal problems with this other than the annoying whining noise
