1997 Ford Thunderbird Left turn grinding

I have recently noticed that the front of my T-Bird makes a grinding noise when I turn (Mainly left) a low speeds. The wheel has a small almost rubbing sound when slightly turned.
The power steerinf fluid is good, no leaks.
I live in the Chicago area and this started happening after some heavy snow and slush.
I do not have a heated garage, but keep it inside to make sure it will start in the cold mornings.
Could there be something frozen in the wheel or need some lubrication?
