Each will have their own experiences, it is all down to what you are comfortable with, personally I am with Stuart under some conditions and Ian under others. If a hub and taper have old damage I use Loctite, and seem to be able to get things apart again. however a perfect set of hub and half shaft I fit sans Loctite, as there should be no need. The worst hub I have ever had to remove was one that had spun and virtually friction welded itself to the halfshaft, It took a very big sledge hammer to remove that one!

Edit: BTW, if you have a heavy and light halfshaft in the same axle, there must be something interesting going on at the differential end as the "light" halfshaft must be rattling around in the differential's sun wheel bush.

I have been using Loctite on the tapers on short taper halfshafts for the past 30 years or so. I use Loctite 641 bearing fit or an equivalent. I only use it along with a correctly fitting key, once the hub has been lapped to the taper. I regard it as a useful aid to, not as a substitute for correct fitting. I've never had a problem getting the hubs off again, but then I do "jump" them off rather than just relying on the puller's forcing bolt to pull them off.

So, it's probably going to be my turn to avoid cyberspace flying objects now
