The Loc-Tite stuff to use is called "Retaining Compound", they have
both medium and high-strength formulations. It is specifically for
bearing "seats".
I have found the retaining compound works great is there has only been
a little chatter or bearing spin in the hub. Any more than that and it
is only good for a very short period of time.
I have had great success with "Speedy Sleeves" (tho' that might not be
the correct spelling of the brand name). I had an axle housing on
which the wheel bearing could move too easily and the oil seal didn't
work too well. The speedi sleeve is a thin piece of metal that you
sort of unwrap onto the bearing seat or the seal seat. The process is
hard to explain except to say that it is sort of like the winding key
method of opening a can of SPAM (Wonderful SPAM; SPAM SPAM SPAM SPAM;
SPAM SPAM SPAM SPAM...)
Again, a good bearing shop should be able to help out...
