The length of one axle is normally slightly shorter than a corresponding
beam, ie. an axle #4 is slightly shorter than a 4 stud beam. So this is
probably why you achieve some slack when putting bricks on either side
of the axle to support it.
But wouldn't your solution be analogous to using bushes to support the
axles, but letting there be some slack between the bushes and the
supporting structure? It appears to me that the effect of this would be
the same as the effect of removing the bushes completely.
