Hi all
Noticed on Friday that the rear casette on my bike was making a funny noise, on closer inspection it has 2-3mm of play. I don't think the lockring has come loose, as the casette's been on there for about a year with no problems and shifing is still ok. Is it likely to be the bearings or freehub assembly, or both? It's a Hope XC Ti from 2003-2004 I think.
Most likely to be the bearings. Easy to replace - [url= http://www.hopetech.com/database/Rear_Cassette_hub_inst.PDF ]instructions on the Hope web site[/url], and lots of threads on here about which bearings to use!
Have a look also at my picture article:

Its for a Pro II but similar to the XC 🙂
Almost certainly its the outer freehub bearing, mine did the same, replaced the bearing and it was fine.
Oh the bearings are 6001 2RS for the XC / XC Ti
Ta very much.
note: the pre-Pro freehubs are different in that the inner bearing is inside the hub body, located with a circlip, and has to be driven out in the same was as the outer bearing. For this reason it's wise to replace it as soon as any wear is detectable, as it's very hard to get it out if the inner race detaches (I speak from bitter experience)
I'm off to a bearing factors at lunch, i'll be doing all three. I suspect the freehub itself will be goosed as well, as the chain's been going randomly slack (which is what happened to an old novatech one i killed) too.
i'll be doing all three
Four bearings in an XC rear hub, probably worth changing them all while you've got it in bits even though the non-drive-side one seems to last forever.
Thanks for that, I would've felt bloody stupid this evening otherwise!
One last question, what do knackered pawls look like?
If the pawls are knackered it should be obvious when you get the thing apart. Either the pawls will have lost their sharp ends or the ratchet has worn. But most likely if the whole thing's loose it's just that you've got some dirt in that's jamming them up and stopping them from working correctly. Have a look at [url= 
]Hope's diagram[/url] so that you know what to expect when you take it apart (don't lose the springs), clean it all up and hopefully it will magically work again - mine did!
Thanks for the heads up, I'm expecting a glorious 'spling!' noise as it comes apart and then half an hour of grovelling around to find all the bits!
