The "stub" axels are the short spindles that carry the bearings for the
wheels. These were easy to replace on the front of most of the TR's, but
I'm not sure about the -6's. The rears, especially for the IRS, is a
complete unit that requires rebuilding the whole hub.
What happens to the spindles is that the inner races of the bearings are a
very light press fit, but can, over time, begin to spin on the axel. At
this point, you are not using the bearing's rollers/balls, but rather have
a journal bearing. Under heavy use, these overheat, and can weld
themselves to the stub axel. However, it used to be possible to have a
machine shop "knurl" the axel, and then resize it so as to take up the
slack. Don't know if that is still done.
Depending on the amount of wear, you can get away with using a new set of
bearings, and use heavy duty Loctite ( the type referred to as "red".)
This will usually work.
I should point out, this is not such a big problem, unless you are running
your car competitively.
