A steerable axle includes a housing defining a ball seat therein, a ball member received within the ball seat and defining a cutout portion to receive a portion of a ball bearing therein, an interstitial space defined by a surface of the ball seat and a surface of the ball member, and a ball bearing disposed within the interstitial space and received into the cutout portion of the ball member. The ball bearing moves within the interstitial space when the ball member rotates along the x or y axis, but is restricted from movement along the z axis. Restriction of movement of the ball bearing along the z axis results in a corresponding restriction of movement of the ball member along the z axis.
