A vehicle truck for supporting a ground contacting device, and in particular to a independent-suspension turnable skate vehicle truck which supports a wheel or wheels or a runner or ski, for example a roller skate boot have in-line wheels or tandem wheels is provided. The independent-suspension turnable skate vehicle truck has one or more deflecting beams attached to a wheel axle hanger and the opposite end attached to a skate vehicle mounting structure. The deflecting beam has at least one horizontal component and/or at least one vertical component. The vertical components resist vertical deflection of the wheel 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 and wobble of the wheel. The truck and mounting surface are adaptable to permit changes to the number of wheels or ground contacting portions, the position of the wheels, and the thickness of the wheels.
