A power driven grinding machine for resurfacing the journal of trailer and vehicle axles in place on the vehicle is disclosed. The grinding machine comprises an elongate frame which is concentrically and rotatably mounted upon the vehicle axle and which includes a powered grinding wheel assembly. This assembly is translatable along the frame in a direction parallel to the vehicle axle and revolves with the frame about the axis. The grinding wheel is adjusted into longitudinal and radial registry with the bearing to be resurfaced. When power is applied, torque resulting from the frictional engagement of the rotating grinding wheel and the stationary bearing surface rotates the entire grinding machine about the axle, uniformly grinding all bearing surfaces about the periphery of the bearing.
