Hi Hardy,
Miatas: Somehow, running against Miatas just doesnt seem right to me.
Axles: I am confident that we induced the failures of the first two HUBS
due to a lousy removalmethod. As you mention, it seems like this could
bleed over onto the axle SHAFTS as well.
Last night, coincidently, I backed off the castellated nut (flush to the
end of the axle) of my 40 year old TR3 axle, applied moderate heat to
the hub, and rapped the end down on the floor to a hard 1/2" pad ( a
nylon-like material used in the machine tool industry)
The hub came loose after about (6) good raps. There was absolutely no
distortion of the castellated nut and the nut spun freely upon
reassembly.
I also have the replication of the factory hub removal tool produced by
a friend. The next step, if the above doesnt work again, (Jack & I have
a couple spare axle assemblies that we would like to disassemble) will
be to apply this hub removal tool, torque it up, and rap it in the same
manner as above. This will save wear & tear on a very nice tool and may
be more effective than banging it with a hammer.
Your thoughts or caveats, if you have a moment?
Regards, Joe
