Result of PUMA is that transfer box requires a Set Positioning Motor - No.10 in the attached RealOEM link. That's the bit that varies the torque between front and rear axles (I think!). Part is on back-order (why does that surprise me!) - so coming from Germany. Xena booked in for surgery at the end of next week.
