Abstract: An articulated support assembly threadably attached to a threaded fastener element on a wheel hub that is rotatably supported on an axle by a bearing assembly. The support assembly carries a dial indicator having an actuator, and is selectively adjustable to align the actuator with the axle longitudinal axis and to place the actuator in engagement with a fixed reference surface provided on the end of the axle. A selectively operable clamping device locks the support assembly against further movement following adjustment. Axial force applied to the hub first in one direction and then in an opposite direction moves the hub between the limits of the bearing internal axial clearance. The support assembly and dial indicator move with the hub, and cooperation between the actuator and the fixed reference surface moves the actuator the same axial distance as the hub to provide a measurement of the bearing internal axial clearance.
