Today when I was pulling into a parking lot I think my steering took a turn for the worst. ha ha =-( I have always heard clunks in my steering but today when i turn the wheel and I'm not moving it's like the steering gives out. I can turn the steering wheel about half way around and the tires respond, but then theres like a grindy, clunky, noise and the wheels no longer respond, as if something is slipping. Is this the steering gear box? Could it possibly be time for a new one? any thoughts?
