I dont really understand. The position of the hub relative to the fixed axle tube is determined only by the wheel bearing. I suppose it is possible the axle tubes have been machined back, maybe to prevent the axle binding in the diff housing, the usual outcome of enthusiastic lapping. But any rubbing would surely have been evident with the car jacked. The axle casing need not protrude far beyond the bearing retaining nut. i dont suppose there is some thin bearing which has been fitted, allowingthe hub to move in?
If a key has been so loose as to be hammered it is unusual for the axle not to be cracked, altho do not necessarily progress. The axle was/ is almost certainly so distorted as to require a lot of lapping to the detriment of the hub unless an old one used intitailly.
It is all very much more simple without a functional split pin.
It is important that the taper makes full and preferably exaggerated contact at the inner end so drive is transmitted before the key..
Other makes (Model A etc) get by with shims in the taper but do not have the very small area and high pressure of the Seven.
