The steering on my 87 GN with 175k miles is quite a bit "sloppier" than on my 26k mile 86 GN. I know the Jeep half shaft is a common upgrade, but I have read where the steering box can have parts that wear out. I tried tightening the allen screw on top of it but apparently that isn't really the best way to adjust it....it should be removed from the car and more drastic adjusting methods should be employed. Advance shows those boxes when I searched for GN, but I didn't recognize the brands. O'reilly sells Cardone, a more familiar brand to me. All have a lifetime warranty however. So, no, I don't plan on autocrossing, just want to restore the steering feel to when it was new. Front end steering parts, bushings, ball joints, etc. have already been replaced. I just clicked on the boxes to get more info. Appears the one for Fe2/Fe3 sport suspension is the one for $172. Most expensive one. Figures.
