I have just had occasion to "suspend" my Europa to replace a tyre. During
this it was apparent that the (mono) wheel could be be moved up and down
about 3/8" without anything else moving. This was traced to elongation of
the LGO5 bushes, which have gone elliptical by at least 20 thou. I have
already found another builder who has replaced them. IMHO they would be
better in a harder material than phosphor bronze; after all there is no
continuous rotation, but they have to withstand the thump of our landings -
and maybe airstream buffeting repetitively loads them too.
