Mike et al., I have no idea how common a practice using the spacer/shim =
set-up was on British cars, but I do know that my M.G. TC has the same =
set up, and I think all the T-series M.G.s, and later models were the =
same. I definitely agree with your argument about the spacer increasing =
the strength of the stub axle. I have also wondered whether, in addition =
to in effect increasing the base diameter of the axle, whether putting =
the stub axle in tension from tightening the nut (without loading the =
bearings!) also increases its strength. I don=E2=80=99t know that, just =
wondered. Back to the TC. Years ago a maintenance book was published for =
the T-series M.G.s that recommended upgrading the front bearings by =
replacing the standard ball-bearing to tapered roller bearings. The book =
said that the spacer and shims could then be omitted, per common =
practice with American cars. What followed over the years was a rash of =
M.G. front stub axle failures! One enterprising enthusiast profited from =
this by making up and selling replacement stub axles. That demand has =
now dropped off as we know the spacers and shims MUST be installed as =
eloquently described in the Healey (and M.G.) manuals.
