Over the last month or so I have developed a clunk in the front end. It happens when the Av is stopped and I turn the wheel sharply to the right. It almost feels as though there is some play in the wheel when I do it. I've already had the shock bushings replaced per the TSB for that. It doesn't do ti shen the Av is moving, only when the extra force is used the turn the wheel while stopped. Any ideas?
