It has been previously demonstrated that the measurement of gearset preload and backlash contains information rich in describing the accuracy to which the gears mesh and rotate. These two parameters can be significant in determining the prospect of long term stability and life of gears. This paper concentrates on introducting defects into gear assemblies in order to determine the fault measuring accuracy of the method. The measurements are made on a typical motor vehicle back axle differential where a direct measurement of preload is not possible once assembly has taken place. The ultimate accuracy of measurement showed residual errors of less than 1 % and revealed consistent detail on the precision of the differential manufacture resolving down to 2 micron of eccentric movement.
