A device and method for operating a multi-axle powertrain for a motor vehicle, with a first axle being permanently in operative connection and a second axle being at least temporarily in operative connection by a drive device via a clutch coupling. It is provided that, when the second axle is decoupled from the drive device and the starting clutch is disengaged, an expected wheel force is predictively ascertained. The determination of the wheel force takes into account a torque caused by a mass moment of inertia of the drive device, and the second axle is coupled with the drive device if the expected wheel force surpasses a maximum wheel force.
