Rear hub service..

My back wheel has developed a little lateral movement after 1100 miles.

No problem, thinks I, I will get some cone spanners & nip up the cones.

But LBS helpfully advises me that I'd also need to take off the freehub too, which I don't have the tools for, and they can service the thing for £15.00 sometime in September - which sounds like a better plan to me.

I have just noticed something similar on my Aksiums. I may have to have a fettle in the next couple of days, although I'm a bit inexperienced with cones (of the un-ice-cream-filled variety).

im a little tea pot
i have play too. changed the bearings etc but my freehub has play in it so will need that out this weekend so i can commute on it still!

The amount ive spent sorting these wheels out could have bought me a new shiny set by now!!!

Cup/cone you don't have to take the freehub off at all (certainly for Shimano and compatible hubs). To remove a freehub, you just need a 10mm (12mm for some copies) hex key.

The Aksium was mentioned - this takes cartridge bearings and you can adjust the pre-load much in the same way as traditional cup/cone, but you can't really service the bearings (you can but you need tools to extract the cartridge). Only a very slight adjustment should see them tight again.

Freehubs with play - check the retaining bolt (if it takes one - may depend upon hub) is tight. If it is secure, you may need a new freehub.

The back axle started to make some horrible noises this evening. So I watched a Youtube video about stripping a Shimano freehub axle, took the cassette off, stripped my axle down, took the freehub off with a 12mm allen key held in a vice, and gave it all a good blast out clean with gt85. The drive side bearings were a little rusty and the freehub wasn't running smooth, but it soon fettled up OK with the relube.

I then relubed it all up again with oil and grease. I think I got the cones tight enough again when reassembling - finger tight enough to run smooth but not loose enough to wobble - and perhaps I should get some new bearings for another time.

Not difficult.. I hope..!

If you leave a *bit* of play / wobble when you're adjusting the bearings you should find that the QR takes it out when you refit the wheel to the bike.

Thanks.. I left it so it all ran really smooth. There were a lot of flat threads on the axle, I take it that's normal ?

It's all back together now but looking at pictures of other axles, they all seem to have flat bits, either no threads or flattened ones.

Mine looked like this one http://www.sjscycles.co.uk/shimano-fh-4500-rear-complete-hub-axle-assembly-3cr-9802-prod22702/

I tightened the cones up by hand, so that the wheel still ran freely, but with no play, then tightened the lock nut into place. If I overtightened the cones the wheel was really rough. There's less play now - pretty much none at all - than there was before I started. I will get some new bearings soon.

Thanks for all the help !
