A steerable truck apparatus for railroad cars for providing for the controlled and uniform yawing of the axles of the truck. The truck apparatus provides for a yawing response which is linear substantially throughout the range of movement of the axles. The truck is further configured with pivotably supported pedestals for equalized load distribution. An improved axle bearing construction accommodates pivoting of at least one of the axle ends. A damping apparatus provides stiffness in the steering response toward reducing hunting of the wheels during straight line travel.
