thanks anyway - its waay to late now - the chap who bought my boat wanted to pick up some spare bearings just incase his epic 2000km drive back to finland with the trailer went as smooth as possible, as far as I can tell he didnt get any spares and it lasted 1800km at least, I've texted him to find out how he got on, im sure it'll be fine as I did both bearings recently (one last weekend)
