After a good compressed air dry off I went to give them a dip in Dexron automatic transmission fluid but - none in the garage
So, had to use the synthetic 0/10 diesel oil instead, nice and thin.
A good soaking in a container for about 15 minutes, drain, reassemble and the all important test ride (performed with no helmet, please don't try this at home folks). I have to say this is probably the best this hub has ever performed, even better than new.
I now totally believe the info on the interwebs about ditching the grease and going for oil instead. And as for paying $100+ for a Shimano " Hub servicing kit" which comprises a container of oil and a tub to pour it into, well they can keep that.
Will it be as long lasting? Who knows, although I do recognise that it will require more frequent attention now that it is only running oil. This in itself should not be a problem, as now I have done the hard work of getting the grease out it only takes about 45min to strip it down, soak and re-assemble.
8 smooth shifting, quiet, no fuss speeds. Yay.

(Not that I'm saying that's a bad thing... just that perhaps beyond the hub's tolerances?
