PURPOSE: An axle assembly run-out measuring device is provided to measure a run-out by rotating a hub bearing in the state the hub bearing is pressurized at a preset pressure, thereby enhancing the accuracy of a measurement result. CONSTITUTION: An axle assembly run-out measuring device comprises a turn table(20), a bolt(26), a knuckle fixing unit(30), a driving unit(54), a socket(58), and a nut(60). The turntable supports an axle assembly and rotates with a driving power of the driving unit. The bolt is perpendicularly lifted by driving an ascendant cylinder(22) while penetrating the turntable. The bolt pushes the axle assembly in the state of being closely adhered to a bottom surface of a hub bearing of the axle assembly so that the axle assembly becomes spaced from the turntable at a predetermined distance. The knuckle fixing unit is installed in one side of the turntable and clamps a knuckle(6) of the axle assembly. The driving unit is installed in the upper part of the turntable and perpendicularly moved by using the driving power of a descent cylinder. The socket is joined to a shaft(56) of the driving unit.
