Clicking Freehub

The last few rides I've been plagued by a click click......click click......click click.... every revolution of the wheel. So I've had the wheel off, removed the cassette, and it's definitely the freehub - you can physically feel it jolt. The wheel itself runs smoothly.

So my question......can it be fixed?

I've never understood how to remove freehubs, if indeed you can. You must be able to :? And in this instance I don;t want to be replacing the entire wheel, as it's still in otherwise very good condition.

Anyways, the hub's a Shimano M745. Any tips?

    New freebody needed sounds like it is about to fail.

    Yes you can replace the freehub (most of the time they are just binned rather than serviced)

    You need to remove the cassette and axel and unbolt it.

    You can probably get a whole hub as cheap or cheaper than a freehub, just take off the bits you need, and get new bearings in the deal.

    You might be right. Just looking on Chain Reaction. £20 for the hub. £99 for a Shimano freehub body :shock:

    I don't know if I want to do my first wheel build on my 'good' bike though :o So I shall look round and see if I can find any cheap free hubs first.

    Buy the hub and swap the body over. And 99 will be the wrong body.

    Yeah, that makes a lot of sense now I've looked again. Deore freehub bodies (which is what I'm guessing the m475 has on) are £20 everywhere. The exact same price as the entire hub. Which is a bit of a pee take...

    And you get a set of bearings for free.

    I'd probs still use the other hub, have a go at refurbing the knackered freehub, and see if I can build a wheel! Got to learn one day.

    One question. On Chain reaction, they have 32h and 36h. What is this - the length for 7 and 8/9 speed cassettes?

    Spoke number. Needs to be the same as your rim if you are going to build a wheel does not if you are using it for spares.
