Sheared freehub

[Frew]

The past couple of days I have had some intermittent bad creaks from my bike while pedalling up hill. after some examination I found that there was some lateral movement on the back wheel.

Being a beginner at bike mechanics, I watched a couple of youtube videos and began taking apart my cassette and freehub to clean and degrease.

When I came to removing the freehub I came to this.

My questions are, How do I procede in removing the remains without damaging anything further and how do I know what freehub to order?

I can see MF staped on the freehub and it is from a 9 speed Giant S-R2 wheel.

I don't see a shear anywhere. What is the actual problem?

 

[Frew]

Thanks for you replies.

Sorry, I didn't show the problem very well.

The following two images show the small curved piece next to the bottom two bearings that has come away from the inside of the freehub.

I was also confused that I didn't have to use a 10mm hex to remove the freehub once I removed the axle. It just came apart.

it looks like your locking ring has disintegrated which would cause the cogs to fall off upon removal of the axle.

Thanks Steve.

So, with having a Sora 9sp groupset, is this the part I would need to order?

And do I need to remove anything else from my wheel before fitting?

What you have done is dismantle the freewheel

Steve - isn't this is a freehub not a freewheel.
Frew - have you inserted a 10mm allen key into the freehub innards stump you have left (ie where the axle was)? Needs to come off. Am trying my best with the images you've provided. That Sora freehub looks right to me.

you've got me wondering now??? Looks like a freewheel to me I stand to be corrected if I am wrong. I noticed Frew had said freehub but...........

 

[Frew]

Hi Ajax Bay,
Yeah, I have tried a 10mm hex ,but it isn't big enough from either side. It looks like I might have to get hold of a 11mm as I was borrowed a 12mm sump tool and it was too big.

 

[Frew]

Sorry Steve, Yeah it is a freehub which I previously removed the 9 speed cassette from.

Well! Took it to a nearby bike shop today and settled on purchasing a new wheel. Might have paid a bit over the odds, but at least I can get back on the road.
