Thanks for getting back to me, my thoughts aswell, but I did change bearings and both seals, pretty sure I fitted them right , nothing was untoward as I remember. It's funny really as it's not a leak as such, not dripping as I've said, it's just a damp finger really, a very slight weep, but don't think it should do it. Not sure whether to leave it and see what happens, sort of suck it and see....your thoughts gents.
