The methodology of measuring the vibration signal recorded on the casing of wheeled armoured vehicle ROSOMAK driving axis is presented. The study was performed on a test bench for different transmission conditions. A preliminary analysis of the frequency spectra vibration signals recorded. The test stand allows investigation of the differential axle gears under load similar to load during duty operation. It was possible by using the combustion engine and gearboxes and load transmission by using the dynamometer break. Have been described. Three methods of attaching acceleration sensors to differential gears: using screws, magnetic washers and probe handle. The results of comparisons of measurement results obtained using these methods. Finally, the sensors was mount by using the screw connections. Selected positions and points of temperature and vibration measures were described. Values of characteristic frequencies of differential axle gears vibration by moving the drive torque through these boxes were calculated. The spectra of the vibration signal determined during testing gearboxes were shown. It was state that of amplitude-frequency vibration spectra of signals recorded at selected points of differential axle gears casing are clearly visible characteristic frequencies but the vibration the bridge gear unit bridges distorted by vibration of the internal combustion engine and gearboxes. In a further stage of research should be included much larger number of the driving axis differentials investigated in various states of well-known technical conditions and should be lead accord to requirements of the active diagnostic experiment.
