What MODEL are you working on? Some of the newer cars have a rack and pinion which is a different procedure if it is an inner.

If it does not have a rack and pinion the following comments will apply. I rarely use a pickle fork. The stud is tapered and in a tapered hole. After removing the nut which might require removing a cotter pin, Strike the end of the steering arm with a large hammer. The force will shrink the tapered hole and squeeze the stud out.

Please always specify what model you are working on when posting your question.

Good luck,
