PURPOSE: A steering linkage is provided to minimize geometric error and over-friction of a ball joint as well as a deflection of a steering angle due to geometric error by recomposing the position of ball joints. CONSTITUTION: When a car wheel is vertically oriented, a pitman arm(3) is vertically and lowerly installed on a gear box(1). At this time, a second ball joint(7) is positioned on a point of contact in an operating track thereof when drawing a tangent line from an installed position of a first ball joint(5) as a point of contact connecting the pitman arm(3) with a drag link(4) to an operating track of the second ball joint(7) connecting the drag link(4) with a spindle arm(6).
