A vehicle truck for supporting a ground contacting device, and in particular a truck which supports a wheel (3) or wheels, or a runner or ski, for example a roller skate boot having in-line wheels or tandem wheels is provided. The vehicle truck has one or more deflecting beams attached to a truck axle hanger (6) and the opposite end attached to a vehicle mounting plate (1). The deflecting beam has at least one horizontal component (7) and/or at least one vertical component (8). The vertical components resist vertical deflection of the truck axle hangers to restrict upward and downward movement of the wheels or other ground contacting portions. The horizontal component controls most twisting motions controlling turning of the deflecting beam. The truck and mounting surface are adaptable to permit changes in the number of wheels or ground contacting portions, the position of the wheels, and the thickness of the wheels.
