Ideally this should be as close to the wheel hubs as possible. In the absence yet of designing a whole new custom free-wheeling hubs beam axle, i decided on a solution with using a dog-clutch disconnect mounted immediately after the reduction gearbox and upstream of the Pajero differential. The hardware i found suitable is the freewheel disconnect part from the front axle of a Pajero-io 4WD SUV. This was suitable because the clutched axle part is a separate module from the front diff body.
