I’m trying to find out if I can still repair my disk wheel that failed on me again last year (freehub freezed, turning my bike in a fixie). I want to replace my freehub, the problem is I don’t know how to get it off. I checked a lot of websites, but still no luck.
Up till now I removed the screws on both sides and my disk looks like this:


So what is the next thing I need to do (besides cleaning it)? Thanks!
That axle should push through and take the free hub with it, giving you access to clean and lube the pawls.
What disc?
Thanks I got it of. But how can I now remove the free hub from the axle?
It is a cheapo brandless disc I bought years ago.
What kind of disc? Not exactly sure but on my wheels I use a 10mm allen on one side and a 5mm on the other to remove the axle then the freehib comes off. Not sure about this wheel though.
I read that somewhere else, but it doesn’t work on this disc. But I cleaned the parts a bit and put everything back together and it seems to work as normal again. Strange… Dont’ know if I can really trust it though. We’ll see.
Thanks
Was the ratchet mech that dirty? Did you figure out what was causing it to bind that badly?
Generally I’d say just clean it. use a good quality waterproof grease and reassemble. Should be fine as long as the pawl spring is not broken and the pawls/ratchet ring are in good shape.
I actually have no idea what I have done (I really have no bike mechanical skills/knowledge at the moment). I tried to get the free hub off, so I pulled it a bit. That didn’t work (although I found out the free hub looks exactly like the bontrager one over here http://www.parktool.com/blog/repair-help/freehub-service and there it says I should be able to get it off easily after removing the axle nut). I did accidentally break the thin ring that keep the paws at the right place, so that wasn’t smart, but I could still secure the paws. But after I put everything back together it worked normally again.
Do I know have to replace the whole thing because of the broken ring?

Pawls. It’s a hub not a cat ![]()
Don’t be certain that ‘ring’ is broken… if it’s like some I’ve seen before, it’s actually like a giant ‘C’-clip (not quite a full 360*, but close) that acts like a spring to help hold/load the pawls in place on the back side of the cassette body.
At least the newer shimano style freehubs, there’s a big-ass 10mm nut (which is inaccessible until the axle is out of the way) that screws the cassette body to the hub shell, but so far that’s not how I’m reading your description…?

Ah, that explains why I only found animal websites ![]()
That is exactly how it look likes. It would make sense, because the ring got off way too easy.
Maybe there is a 10mm nut underneath, but I couldn’t get the axle off. I probably just have to use more force to yank the hub of the axle, but I was affraid that I would destroy the whole thing
When I worked in a shop we had a Morningstar freehub buddy. Once the axle is out, you jam it on the end of the freehub, and pump grease through it into the freehub. If it fits on your freehub it should allow you to regrease without removing it.

For the pawls you want to use something like a heavy oil, not a grease. Grease is too thick and can make the pawls stick in one position.
