Lawrie,
I'm learning more about this than I really wanted to know...one
technical question remains. What kind of pressure is necessary to put
the new hubs on, after removal of the old ones? And a corollary
question - why were they pressed on so tightly in the first place?
There would seem to be very little lateral force applied to the junction
of half shaft and hub extension.
