A nondestructive test apparatus and method for checking grease packed bearings in which the inner and outer races to be tested are sealed and then low pressure aeriform fluid is directed to the portion of the bearing packed with grease between these races whereby, if there is relatively free flow of this fluid therethrough, it indicates the absence of grease or less than complete coverage of grease in the bearing.
