... where to get replacements from without me taking my hub apart? There seems to be a bit of play front and rear but if I tighten the QR skewers it seems to dissapear. Now I think it could be the bearings but is it possible the bushes on the QR skewers are wearing? If anyone has any info it would be much appreciated. I can't seem to find any part numbers on the Mavic site!

Have you tightened the bearing preload collets on the hubs?

I haven't, but I'll give it a try cheers!
