A minor oil leak (sweating) from under the front bearing seal of the main gear is allowed, but if the gearbox and the bottom of the car above the main gear are heavily oiled, the seal should be replaced

The transfer case is designed to change the torque in magnitude and distribute it between the front and rear drive axles

The axle shaft assembly with the bearing is replaced if there is increased noise from the rear wheels of the vehicle compared to normal noise both when driving straight and when turning.
In this case, there is increased axial and radial play of the axle shaft
The car uses direct current electrical equipment with a nominal voltage of 12 V
