My axle felt like it was grinding when I spun it. So I’ve taken my cassette off to look at the freehub body. The pulls were rusty and full of water and gunk so I’ve cleaned it and put it back together. It’s the wheel bearings that are crunchy and need replacing. I do t have any new ones so I put the cassette back on and then noticed there is play in this bolt.
After tightening the lock-ring to secure the cassette, I can now pull the entire cassette off with the freehub body.
Any ideas where I have gone wrong?
Is the axle threaded? If so is that part tight? What hub is it?
If it’s a push fit end cap, the cassette will pull off when fitted. Happens on a few brands of hub like Hope. May just seem easier to come off now if you had that end cap off recently but when everything is fitted on the bike it’s not an issue.
It doesn’t look threaded. The hub is A Shimano Boost 12x148, sealed bearing.
Once I’ve fitted the wheel to the bike it all seems secure but I’m not sure it was like that before I tinkered.
Is it actually a Shimano hub or just a Shimano compatible freehub. Didn't think Shimano made any hubs with sealed bearings.
This is the tech manual;
page 13 onwards. It's not sealed cartridge bearings but cup and cone (clearly there is a seal). Page 17 suggests the part in your picture that is loose is push fit so it may not be seated properly. Did you remove the cassette from the freehub while reinstalling? If not try that as it'll be easier to work out if the end cap is seated correctly.
Thanks nixie.
I’ll remove the cassette and try reinstalling the freehub with the push fit cap. Looks like I missed that step.
Removed the cassette and freehub body and pushed the end cap until it clicked and it seems to have solved it.
Had a quick test ride and my hub is so much quieter now but a lot smoother. I only used a light coating of grease on the pawls.
👍 good job.
