It is important the hub puller is a good fit. If the threads become damaged the process becomes complicated! If someone applies the brakes heavily may hold the hub adequately. On standard sytem can realx the front adjustment.
The religious ritual of wholescale lapping of hubs was questioned in the old website and caused a furore. Yet the original axles and hubs were intact on my well used car at 110,000 miles with no lapping.
The best course of action will depend on the state of the parts. If the failure has followed from the hub having been loose the hub will likely be too damaged to warrant reuse. New are available. As above, prolonged lapping can lead to the axle jamming inside the diff, and the new axle becomes non standard. Investigation with thin engineers blue or somesuch is worthwhile. Provided it does not contact mainly at the small end a new axle and new hub may not benefit from amateur lapping. The taper must make full contact inboard of the keyway. (Not sure if this is practicable on all thin axles) Even if undamaged, it is likely the hub has been extensively lapped in the past.
The bearing load (and crown wheel mesh) is determined by the thickness of any gasket separating the diff halves. It is prudent to compare the assembled thickness. Any change will require compensating adjustment of the left side. Beware the bearings are not overloaded before any readjustment.
