Abstract
A tool (10) and method for measuring endplay between an axle shaft (36) and an axle hub (34) of an axle assembly. A mounting plate (22) is fastened to the hub, and one end of a through-rod (16) whose ends protrude from opposite ends of a housing (14) of a fluid-operated device (12) is fastened to the axle shaft by applying an external force to the other end of the through-rod while fluid is not operating the fluid-operated device. With the mounting adapter and the through-rod secured as described, fluid is delivered to the fluid-operated device to move the through-rod relative to the housing, and the resulting relative movement between the through-rod and the housing is measured by a measuring device (48).
