Vibration from BB or freehub, when freewheeling over 45 kph

[ultyguy]

Hey all, wondering if you can help me out with an issue. On my training bike (that I admittedly don't coddle at all) I have been experiencing a weird vibration when I freewheel over around 45 kph. If I start pedalling again then it goes away. The chainset is 2009 Campag Centaur and the rear wheel is a Kysrium Elite 2009.

Can't figure which it's coming from?

it's the bushing in the rear wheel's freehub body. it needs servicing, essentially a relube.

many Mavic wheels do this. Just remove freewheel body, clean it and relube internals (just several drops of oil are enough)

Thanks guys, any particular lube?

Mineral oil is the recommended lube.

And if it's worn out, there is a very nice mod available on ebay that replaces the bushing with a bearing and a nice aluminum spacer.

Thanks Weenies!
