Each of the combined segments together form an inner surface of the female portion and each has its own ball tracks extending substantially the length of the female portion. A unitary male portion has an outer surface defined by a plurality of axially extending ball tracks. A unitary cage is located radially outward from the male portion and radially inward from the female portion. The cage has a plurality of ball apertures with balls located in the ball apertures. The balls are in contact with both the ball tracks in the male and female portions for selective movement of the male portion with respect to the female portion.
