The friction of the pinion shaft with nothing else fitted to it should be set to 120-140 N cm (Newton centimeters not Nm!) with new bearings. I assume the combined friction of pinion against crown wheel fitted to axles and wheel bearings would register less than 10 Nm on a torque wrench.

I've just checked in the FSM with regards to the 180Nm specification. I didn't realise that that is the minimum needed for this seal replacement procedure (chapter 35-530). If the book says you need to get that minimum torque then you need to comply with the book! It does strike me as a dangerous thing though as over tightening the pinion nut and crushing the washer / spacer too far means you then have to remove the differential from the car - take out the crown wheel etc - take out the pinion shaft and fit a new crush washer...
