I recently got my car aligned and balanced and it was smooth as a baby's behind. My wife was driving the car and the front passenger side wheel was almost flat, she drove on it and pulled the tire completely off the rim . Took it to my trusty TL mechanic and he checked it over and replaced the front passenger CV half shaft...lastly he re-aligned and re-balanced it. Now the problem I am facing is the steering feels unresponsive between 11 and 1, and on full turns after 11 or 1, the steerring tightens up again. Compared to before the wifey drove it, the steering is awful, especially after 60 MPH...Anyone experience any similar steering issues?

One note, the power steering box was replaced at 15K, the car has 72K on it currently.
