I do wish you would stop swearing, it's very rude you know.
I offered a quick fix solution which some people might like to follow, I have made it very clear I have never done it on any of my own Series or coil
With regards the relevance to the 101, haven't you worked it out yet? It isn't gators as the 101 was never fitted with them (had them on my S111 but didn't like them as they can hold muck if/when it gets inside, glad the MOD saw sense and didn't fit them as standard to the 90/110 fleet), it's your dismissal of the alternative method I suggested. The fact that the swivels are welded to the axle-casing on the 101 makes seal replacement via the normal method a trifle difficult.
Replacing the swivels themselves is a very expensive job as the whole axle casing has to be replaced however I was lucky, new seals and I had 6-years leak-free ownership but there I go, wandering off the point again......
