Scratching noises while turning steering wheel

Where are these noises coming from, the steering wheel or outside the car? If the steering wheel, try changing the position of the steering wheel a little higher or lower and see if it makes the problem go away. If its an outside noise, get the front suspension checked out.

It is definitely the steering wheel. It is already at the highest position, as I am tall and don't want to lower it and have it touch my legs.

I had this problem with steering wheel on one of my cars. As soon as I moved it slightly away from the stopper, the noise stopped. Didn't have to be very far, just enough that it wasn't forced against the stop. Can you lower the seat any to make up for it?

I would bet money that it is nothing more serious than the bottom of the steering wheel making contact with the top of the steering column cover. Try a bit of lubricant (Armor All) on the top of the cover.
