The shims are what gives the end-float - more shim thicknes gives more
end-float and vice-versa. The nut tightens up through the inner race of the
outer bearing, the shims, spacer tube and the inner race of the inner
bearing so none of the 40lb ft (minimum) is actually applied to the bearings
themselves - that is the whole point of the end-float. The 70lb ft
(maximum) is to give further tightening to the first split-pin hole after
40lb ft is reached. This is said to increase the effective thickness and
hence strength of the stub-axle, as well as prevent the inner races spinning
on the stub-axle.
