Clicking noise from rear wheel (mavic aksium)
Hi,
Two issues here and I realise I may need new parts.
EDIT: Adding a youtube link for completeness:
id = zwOmi1RRLIc
it's youtube.com/shorts/id
I'll update with a full link when I can.
Note, pretty sure the sound is from the axle being too tight, but see my later post regarding this
Two issues here and I realise I may need new parts.
- My chain was getting slack when coasting and the rear derailleur would sort of snap forward. I read you should lubricate the pawls so I did. I did notice the little brackets that the pawls are held in (those red things) are slightly snapped. I'll probably need some replacement ones I guess to stop this from happening.
- After dismantling and putting everything back together, it's now got a horrid clicking/snapping noise whether I'm pedalling or coasting. What have I done? Guessing I've tightened something too much, but I didn't think I used much force anywhere

I have no idea what you did. It sounds like it’s toast. Nothing is slightly snapped, that’s like being a little bit pregnant, lol.
I am not familiar with Aksium parts, hopefully someone that is will chime in for you.

If you are posting pics, just put them in the Gallery here on BF and tell us they are there.
For video, youTube or imgur.com works well. Just give us the part of the URL that comes after the .com and most of us can find it from there. And then remember to tell us what site their hosted on. Or if you are good, then obfuscate the entire URL.
The limitation on newbs is annoying, but many high traffic volume sites do this to limit what SPAMMERS can do. After you get ten posts, it'll go away.

Did your maintenance include breaking the chain? (As in taking it apart…not becoming inoperable.) Often, when putting the chain back together, the link joint will be TOO tight for it to hinge properly. If the link doesn’t hinge properly, it will cause the rear derailleur to jump as that link goes through the pulleys. The stiffness can be eliminated by turning the chain tool around, and putting it on the opposite side of the link, and applying just a big of pressure to loosen it up.

I've serviced many Aksium wheels. Riding myself on them today. Great wheels for the money, but they do require more frequent servicing than say Shimano wheels.
If you've removed the freehub to lube the pawls and ratchet ring, and now while riding you hear a clicking or snapping sound, then the pawls are likely loose inside the freehub. If you've ridden more than 10 feet in this condition, it is likely that the pawls, the ratchet ring and the hub body itself is irrecoverably damaged. Remove the freehub again to recover the mangled metal shards that used to be the pawls.
Good news: these wheels are easy to find and cheap. They are sold in pairs real cheap on AliExpress, but I don't know how genuine and functional these versions would be.

No I didn't break the chain Dan, that's definitely not the problem.
I did a bit more investigating, so let me add a few more details (as I am getting somewhere!)
I should have included this info when I posted...
When I first removed the hub body, I saw that the yellow "bushing" (?) was snapped (the part that sits between the hub body and the rubber washer on the wheel) so I went to a LBS and they sold me a used mavic freebody that looked identical to mine. I went home and fitted that new to me free hub body (so just replaced the old one). It also came with some pawls that looked ok, so I used them. I tightened everything up after watching many videos, and then found the axle doesn't spin freely - that is what I think was causing the clicking noise. I then found a video that showed this problem, and they had a missing washer - the washer that sits between the freehub body and the hub. The purpose of this washer is so that when you tighten the freebody body onto the hub the axle can still turn freely. I have this washer, so still not sure why it was happening. But I tried adding a second washer and this issue clicking / snapping issue went away and I could tighten the freehub body tight and the axle still turned smoothly. However, the coasting issue with the chain going slack still happened - even though I cleaned everything and added mineral oil.
I didn't like the idea of using two washers (is that a problem? i can find a thicker single washer, but I'm surprised that would seemed a like for like replacement caused this issue), and given that I still had the problem with the chain slacking, I went back to the old hub and tightened it all up (with 1 washer only) and the axle spins freely, but still having that issue with chain slacking. What else can cause the chain slack when coasting problem if not the pawls? I've now tried two different hub bodies and two different sets of pawls...
