Ah, i didn't realise Volvo used actual bearings for the pilot bearings - many manufacturers literally use phosphor bronze bushes!
For the cost of the bearing, i'd agree with the advice you've already had and change it. For the sake of a few Euros it would be silly not to!
As for the bottle of wine, i'll take the thought as payment and get one tomorrow - Italian red of course and enjoy it while eating tagliatelle bolognaise!
