I've not had the rubbers all the way out of my facelift, but I can't see why the door would have to come off - I've never had to remove the door on any other car to get the rubbers out.

Where in Berks are you? I'm near Bracknell.

 

It does not.

Make sure you lube up the rubber with some dishsoap....it makes the install much easier. I did it in the summertime, when the temps kept the rubber soft.
