You can service the bearings on one side easy enough. But I think when the other side is gone you have to 'send it back to Shimano' where they'll replace the internal assembly. I think buying the internal assembly part (and having a go yourself) isn't cost effective because of the price of the part.
Son can be serviced in the UK but I have no idea about SP.
