Dana 70HD and 14 bolt full float is about 90ish or so foot pounds for those, wouldn't go anymore. They are 3/8 bolts after all

power and weight. full float axle(that is thje axle shaft that you are tightening) allows more weight to be bared because the differential and its tube does the work. THe shaft just turns the wheels from thje pinion.
