just yank it up tight with a bar about 50cms long,their should be collapsable spacer between the taper bearings just tighten it like a professional without overtightening it so and shearing something .handfull of grease in the diff casing to slow/stop any oil leaks top up with ep 90 and away you go,the crownwheel to pinion setting is just a little wiggle woggle ,or you could use a dial gauge but its quicker and easier ,too tight and it whines and too much play and it clunks,nice little wiggle woggle and it will work fine .trust me

There isn't a torque spec since those bearing are pre-loaded. You place the unit on a good known vic and get a breaker bar and you might even have to put an extention on that and you begin to tighten unitil you fell the bearing start to load...a little extra short turn wouldn't hurt at that point.

There is no torque specs,this nut has to be tightened back like it was ,the best thing to do,was,to late now,is to use a torque wrench to remove the nut,and remember the torque,and when replacing it,torque it back to that spec,the reason being,there is a crush sleeve between the front pion bearing ,and the rear pinion bearing,and it has to be crushed to a certain amount,to aquire deepness into the ring gear,anyway just give it about 25 lbs torque,any more the crush sleeve will crush even more and the deepness of the pinion will be too much.
