I did my old 300 tdi disco ones. Use a drill but it'll have to be a
quality bit or you'll snap them real quick. Put gentle side ways
movement on it to saw the rubber out. Then, get a hammer and chisel and
gently tap around the edge of the remaining shell. It'll soon pop out
with plenty of WD 40.

Don't bother with a press, a good vice will press the new ones in with
copper slip on them. Make sure you have some old sockets or something
as spacers. Use a big washer between the vice and the bush to get an
even pressure across the thing to push it in. Keep checking with every
turn to make sure it goes in square. Take your time, it'll pay off.

If done out in the open and avoiding resting the links on an open petrol
can the risks are minimal. If I didn't know better I'd think that you
doing a passable impression of a government minister - give them more of
the nanny state!

... and the drill is not without risks, either!!
