In general, it should not be possible to remove a UJ
without using a 'persuading tool' such as a vice. This is
because it is intended to be a tight fit and you need a vice
to assemble the parts in the first place. Coupled with the
effects of time and corrosion, you may even find that a
vice is not adequate - I have had to resort to a flypress
before now.
The only exception to this is when the yoke holes have
spread so that the UJ caps are loose. If this has
happened, then a G clamp will work but then, so will a
finger! However, whichever yoke has this problem will
have to be replaced. Loose UJs give rise to a knocking
noise which the inexperienced often incorrectly put down
to being a duff diff. You can usually see if you've got this
problem by looking at all 8 bearing caps in turn while
they're still on the car. If you can see a ring of bright steel
round the edge of a cap, under the circlip, then it indicates
that the cap is loose and rotating in the yoke. The UJ and
the faulty yoke should be considered scrap ( which is a
shame if it's the one on the driveshaft).

Yes, no problem. But you'll have to undo either the
spring/link bolt or the rear trunnion bolt in order to remove
the unit. I would suggest the latter and replace all the
rear trunnion components while you're at it - including the
bolt. These items are too often neglected and, at best,
seize up. At worst, the bolt shears and the rear end goes
awry.
A nice job for Christmas. At least it's warm where you are.
They're threatening snow in London.
Good luck.
