Why does my 2006 Mustang make a screeching sound when making a sharp left turn?
Over the past week, I've been noticing a troubling sound come from my 2006 V6 Mustang (which has around 70k on it). If I am going below 10 mph and am making a sharp left turn, there is a screeching sound coming from the car. While I am not 100% sure, it seems to be coming from the front left wheel. I can't be sure, but it sounds somewhat like a scraping sound, as if metal is sliding gently across another piece of metal.
I had taken the car in to the dealer around two weeks ago to have a recall fix done on it, they told me that they noticed the brakes were beginning to go out on it and that I should get it checked fairly soon. I am assuming that the screeching sound I am hearing is somewhat related to this, but I'm just not sure. And perhaps I'm just a little cynical, but I find it odd that I begin having this problem only after I'd taken my car to them.
Any guesses? I am in no way proficient when it comes to this area, but I am thinking it may just be time for new brake pads. The brakes are starting to squeal a bit and make some "scrubbing" noises when coming to a stop, especially if I am coming down a hill. But also, it really perplexes me that this would be happening only while making a sharp turn. What would be the reason for this?
Can anyone who has some experience help me out with this problem? Thanks!
No, it doesn't necessarily have to be turned all of the way. Sometimes just a basic 90 degree turn at a four way will bring about the noise. What's odd is that it comes and goes. Sometimes I will make a U turn to the left and I don't hear it. But sometimes I may just be making a 45 degree turn and I'll hear it.
Edit: Like I said, I'm not at all proficient in this area. But I have some good friends that work at a garage and can help me out with this. Is there anything I should tell them when I take my Mustang to them to help me out with?

Reason: (Added Info)
Also, I should mention that when I took the car to the dealer, the mechanics there did a thorough diagnostic check. The info sheet they gave me indicated that virtually everything was in great shape. This includes the power steering system / fluids, as well as the internal braking system / fluids. The only thing that they indicated to me was that the brakes / pads themselves were beginning to show signs of wear.
I would venture a guess that this is what is causing the issue, but I just can't be sure. Especially considering that it only really acts up in sharp turns.

i took my car to the dealer, they blew up my catilitic converter, and i KNOW i had a bolt on the bottom of my header when i took it in... because i was in their parking lot under my car.....
but aparetnly bolts just disappear, and ford cats arent under warrenty when the car still is

Actually the emissions warranty is longer than the powertrain, think it is 8yrs in CARB states, check your owners manual. don't let them screw you for cat. converters.

I've checked my power steering fluid myself as well, it's at the suggested level.
well I would at least investigate a little more in the brake area if the dealership said your brakes looked worn. Some cars have a audible warning thing on them when the pads get down to a certain thickness. I don't thionk Fords have them though, but I'd check the brakes anyway.
Get the left front up in the air, pull the wheel off, turn the steering wheel all the way right so you can see right into the back of the caliper and take a look at the thickness of the pads.

maybe thats the pumping sound of the power steering thats why it doesnt show anything in your diagnostic tests. i also heard that sound sometimes specially when iam backing up and turning at the same time, and thats what they told me(dealer).
Yes, you can hear the power steering pump when your spindles hit the steering stop. It makes a noticeable hissing or whirring sound. That is the sound of the impeller stirring up fluid that is not moving. It is much the same as a large fan that gets covered with a curtain or something on the intake side. That, in itself is not a problem, however you will hear the power steering pump EVERY time the wheels go to full stop in either direction. It is never intermittant.
What you are probably hearing is one or more very worn brake pads moving up against the rotor as the steering mechanism soaks up the changes in weight transfer and flexing while you are turning. You should not be able to hear this. It is probably due to at least one pad being worn completely out. If there were any pad material left, this rubbing would not be noticable. Since you are hearing squeeling and scraping from the brakes under normal use also, I am willing to bet your pads are history and you are cutting into your rotors. Look at your rotors through the wheels and behind the wheels to see if there are parallel grooves in them. If they are grooved, your rotors may also be worn beyond the point where they could be resurfaced.

If it looks right, it is right, and I decide if it looks right. Paraphrasing Sir Sydney Camm (of Hawker aircraft IIRC)
Had a similar issue with my F150. Turned out to be a brake rubbing something on the wheel only during a right turn. Just needed a quick clean up and adjust. Mechanic said it was common in Fords.
