    Fairly old hope xc rear hub and its started to feel a bit ropey so decided to stripand put new bearings in.Unable to get the shaft to move after lots of taps with wood and a hammer(I know I should get a proper nylon hammer).
    Am I hitting it the right way?

    Thats going nowhere with a bench under the otherside. And whats wrong with a sledge hammer?

    Drop an old bolt/screw in the axle to protect it & then whack it with a proper hammer

    As he says, rest the centre of the hub in that gap, then smack firmly with a rubber mallet/wood, don't use a metal hammer as you may damage the end of the axle.

    I assume he's lined the axle/spindle up with one of the holes in the workbench (black and decker workmate….?)

    I took mine appart for the first time last week, didnt change bearings, but can offer a little advice on re fitting the freehub, I held all the pawls in place on the freehub with a rubber band and inserted it into the hub and then just snap off the rubber band before pushing it home…

    Looks like you've got the axle in a hole in the 'bench' yes?

    Well, that hole needs to be bigger then the bearing as it's the bearing you want to move, isn't it? 🙂

    it'll still jam when the bearing gets to the bench, but yes in essence that's how to do it. I know you;re afraid but you really do have to use some force when it's seized

    I just did this last week and couldn't get it out with a wooden mallet, so used the bolt in the axle technique as above and smacked it with a hammer, came out a treat. I am currently looking at new bearings, is it worth buying high quality NSK or similar bearings or just using the cheaper ones you can get from a bearing supplier?

    All correct assuming, as PP says, the hole in the bench will allow the bearing to pass.

    You need a proper percussive tool and to hit it markedley harder than you think you should.

    Yep got it over the hole just to get it started, then will move over to the gap.
    Goes to find a bolt to fit down the axle…….

    disc rotor bolts are the perfect size

    It's best to use ear defenders as the noise is loud and masking it allows you to hit it harder 🙂

    disc rotor bolts are the perfect size

    yes, but one you probably won't want to reuse…

    Done that and now sorted now to get the bearing out of the freewheel any ideas is it a case of tapping from the non drive side.

    Thanks for the help so far!

    I have had experience of cheaper bearings not having fine enough tolerances i.e. there is play after fitting them to the axle. Might have been one dodgy bearing, but it's something to be aware of

    In my experience buying a new freehub saves a significant amount of swearing at this stage 😉

    Ah, the perfect post! I was planning on doing this at the weekend. Rather than use the piece of wood and bench technique, i thought i might get the tool set from hope. Does anyone know whether the Hope Pro 2 hub tool kit also works for XC hubs? I've got both and don't really want to buy two sets of tools if it's not needed

    Is there two bearings in the freehub with a spacer getting a bit nervous now as I,m getting into unknown terrority.

    Yes, 2 bearings in freehub, outer one can be drifted out using the end of a screwdriver on the inner race, need to move the spacer across to get access, once outer is removed the inner one is held with a circlip.

    Yes rich, two bearings and a spacer. If you havewn;t seen it yet, this is the best guide I've found

    http://mountainbikerides.co.uk/fettling/hope_hub.htm

    Don't forget the inner bearing has a circlip holding it in place that you need to take out before you try to whack itout

    tip- 1 1/8th steerer tube cut off is samesize ish as outer race for whacking new ones in. And use grease everywhere.

    The freehub bearings can be a pain to remove and fit!
    To remove, lever the spacer to one side to make it easier to remove the 1st bearing. After you've removed the circlip, bash the 2nd bearing out of its seat, then have fun trying to get it started/past the 2nd bearing seat where the 1st bearing used to sit!
    Tip on installing freehub bearings:
    Once you've installed the 1st bearing and circlip, slide the freehub onto the axle and check and double check that you have installed the correct spacer that goes between the bearings, install the final bearing using the axle as a guide. This makes the installation of the 2nd bearing lots easier and insures that the 2 bearings are aligned properly. Don't over do bashing the final bearing in, as its easy to knock it in too far causing side loading and a none too smooth bearing!
    Remember to refit the spacer between the freehub and hub.
    Have fun.

    I know you're past the problem in the original post now, but for reference, if the axle doesn't move easily I always use a 3 arm puller hooked round the spoke flange to force it out (with a penny between the shaft of the puller and the end of the axle).

    Hitting the axle with any kind of metal hammer is a complete no-no

    Oh my god,why are the "look so simple jobs" a pain in the ass,first bearing out and spacer plus circlip,now the final bearing feels smooth and grease looks ok ish but have tried to take the last one out but chickened out when it neared the lip as it needs to be bang on straight when extracting and im bodging it with the "not right" tools.

    Sits down and has another cuppa………

    nice to know I've been there, done that, bought the t shirt and found it as big a pain as you 😆

    I use a nine inch nail, rather than a screwdriver, they have to lip to work with. That and a big hammer.

    I never understand the problem people have refitting freehubs, hold pawls in with thumb, index and second finger, twist and shove home, refit endcap, done.

    I love working on XC's, so easy to look after if you have circlip pliers.

    "have tried to take the last one out but chickened out when it neared the lip as it needs to be bang on straight when extracting and im bodging it with the "not right" tools"

    Well you've got to change it now as bashing away at the inner race will probably have done some damage to the bearing.

    Just get it done man! You've got the same tools as everyone else probably – old screwdrivers, bits of metal and a hammer. Only remotely specialist bit of kit you might find useful is a vice to hold the freehub while you knock out the old inner bearing and install the new inner bearing. To install use an imperial socket fractionally smaller than the bearing outer diameter (I forget which size it is) with an extension bar fitted, this will help you to keep it square while you tap it in.

    I use some washers and a QR to drive the new bearings in.

    I have heard it said that pouring boiling water over the parts to be removed helps them move initially.

    a spark plug socket is the ideal drift for installing bearings.

    Heat the ruddy hub! tie a rag around it and pour a kettle of boiling water over it – it turns a tricky job into an easy one 90% of the time.

    Freeze the new bearings as well.

    AS TJ says, if you freeze the new bearings first they drop in beautifully!
