A method for detecting faults, or inaccuracies in a test object which is a splined wheel having teeth of substantially similar shape, or in an object having a similarly shaped toothed profile, including rolling the test object against a counter splined wheel of a testing device with similarly formed teeth, which testing device includes a plurality of gauging elements which are introducible into the spaces between the two teeth of the test object, each gauging element having a curved testing cross-section engageable in the spaces between the test object teeth, the radius of the testing cross-section of the gauging elements is selected relative to the structure and shape of the teeth of the test object so that the testing cross-section rests on the test object tooth flanks at points between the top and the base of the tooth, alternately only one of the testing cross-sections, then two of the testing cross-sections, then again only one of the testing cross-sections and so as, is introduced in the spaces between the test object teeth or teeth of a master reference object, the differences between the insertion depths when only one of the testing cross-sections is inserted and when two of the testing cross-sections are inserted, are measured and recorded by determining a corresponding change in the distance (a) between the axes of rotation of the counter splined wheel and test object, the above mentioned procedure being performed continuously due to rotation of a roller wheel, or a corresponding testing device, which includes a number of testing cross-sections.
