A 6×2 tandem axle drive has an auxiliary 6×4 drive that is automatically engaged and disengaged. A forward rear drive axle has an input shaft with a clutch selectively driving a simple transfer shaft. A rearward rear drive axle is driven by an inter-axle transfer drive shaft that receives power from the simple transfer shaft. At least one wheel disconnect clutch is operable to selectively connect and disconnect at least one wheel of the rearward rear drive axle from the differential of the axle. A control module is configured to selectively place the vehicle in 6×2 mode by disengaging the clutch on the input shaft of the forward rear drive axle and disengaging the wheel disconnect clutch, and in a 6×4 mode by engaging the clutch on the input shaft of the forward rear drive axle and engaging the wheel disconnect clutch.
