I have a 1986 GN and my steering is very sloppy. If the road has any contours to it, the car will follow it. I tried a suggestion to tighten up the steering box and it made no difference so I ordered a new box. With the new steering box, different rims and tires, and a front end alignment it still has made no change. The mechanic that did the work said that the rag bushing looked like new and the suspension pieces were all good. What could be causing this?
