- Freehubs can cost a fortune, can be a nightmare to track down, and some you just can’t get anymore. But what if I told you you could just repair the old one? Well, in this video, I’m going to show you exactly that.
I did a video a few weeks ago, and in it I noticed that the freehub bearings on the bike I was working on had failed, and I said I’d do a video on how to fix it, well this is that video.
To do this job, you’ll need the following tools:
Your normal spanners and hex keys.
A Blind Bearing Puller Set
A Bearing Press Set
A Pick or Small Flat Screwdriver
Some Degreaser Spray
A Clean Cloth
Light grease
Light oil

I know that accepted practice is to always replace bearings that are removed by punching or pulling on their inner races, but I recently overhauled the freehub on my 20+ year old bike, which required me to remove both sealed cartridge bearings by punching them out from their inner races.
Neither required an excessive amount of force though, and upon examination both appeared to be working fine and rolling smoothly. So although I had purchased replacement bearings, I decided to try to reinstall the old ones and see how well they performed.
And so far, no issues at all, smoothly rotating wheel, no noise, rubbing, seizing or wobble, just like new. Now I don't have that many miles on them, not even 100, but I've gone over a fair number of small potholes, bumps and such, and they still spin just fine.
I'll keep a close watch on things and if I detect any issues I'll replace them with the new bearings, but so far so good. Anyone else try this and how did it work out?
Excellent video again Jon, completely agree when you mention that using the tool even once or twice will pay for itself, also by buying your own bearings you know exactly what is going back in. I've used Bearing Pro Tools for removal and installation of cartridge bearings on a Fulcrum hub and they worked fine, keep up this content Jon ,really useful, thanks for the time and effort you take to produce these.
Hi Neil,
Glad you enjoyed it. Yeah, I've seen a lot on the Bearing Pro Tools stuff. Have also referred people to them in the past. They do some 'Hub Specific' tools that are great, like the over axle press (Or whatever its called!!).... great tool that solves an annoying problem.
More videos planned 👍
Great presentation. I will never do this type of repair on my own but I feel more knowledgeable when I bring it into a shop. Keep these shop presentations coming!
Will do, Mike. Glad you enjoyed it 👍
Thanks for the bearing press recommendation. I bought one and it made fitting my first press fit bottom bracket and enjoyable task. I have seen a video of bottom bracket extractors which look interesting and less brutal than whacking out the old cups
Hi James, "an enjoyable task"..... thats what bike maintenance should be. There is nothing nicer than working on your bike, putting stuff together, and it all goes smoothly. I don't see many press-fit BB's nowadays. If I did, I'd do a video on one.
Great how-to video. Having some one walk you through the process makes it a whole lot easier. Good to know what tools to use & what to be mindful of when replacing those bearings. I guess the hard part will be tracking down a new set of bearings?
Hi S.J.
Glad you enjoyed it. As I say, the best thing to do is to measure them. If you type into Google "Bearing 28x15x7", you'll get loads of results for 6902 bearings. Measuring is best. 👍
Excellent as always
Thanks, Jason 👍
Really great and informative video. Great work!
Much appreciated!
Excellent video!, just what I needed. Can you also make a video about servicing/changing the bearings of the pivots in an MTB bike please?
Thanks. Frustratingly, I don't get many MTB through the workshop door, so we could be waiting a while.
Ali express currently have some good deals on bearing puller kits. Same or similar kits from £15 - £25.
Another brilliant video, thank you.
Good to know!
Except many Aliexpress sellers are scammers.
Great video!
Thanks!
Your thumbnail hast a small typo: "Freebub" ... Great video as always!
Well spotted, Garfie1d73, thank you so much for letting me know. Sorted. Was only a matter of time before I did that....... And I'm sure it'll happen again!!
Another great video with very clear instructions. What sort of cleaning agent do you use?
Hi Frank,
Glad you enjoyed it. The dirt wasn't too bad, so rather than dilute some degreaser, I was lazy and just used brake cleaner 🤣🤣🤣
Excellent video, is it possible for you to do a video on servicing the Vision Team 30 Disc wheelset bearings and how to remove the bearings and how to put it back together in a rear wheel. This will a great video for us out here who owns Vision Team 30 disc wheelset.
To be honest, Shameel, I've not seen any Vision Team wheels in a while. I used to see a lot of Team 25 rim. Think I may even have a pair somewhere. I'm pretty sure that Vision use a Novatec centerlock hub on that wheel, which is what both Fulcrum and HUNT use. I'm going to be doing a wheel bearing video very soon, and I suspect the process will be very similar, if not the same.
Great video mate, what grease gun and grease do you use, I like it 😊
Hi Dave,
Yeah, great isn't it! Park Tool mate. Here you go:

Great video, thank you. Which brand replacement bearings do you tend to use and where do you tend to get them from?
Hi Majid,
My rule is, if you want them to last, buy steel. If it's a budget job or, say a winter hack, I use basic steel bearings bought in bulk from Amazon. They run well, and last. Link below:
amzn.to/3SZ0gkp
However, if there is a request for a 'Branded' bearing, then I go to these guys, as they sell both Enduro and NTN:
www.airevelobearings.com/
Hope that helps.
thanks a lot for sharing. i wanted to service mine freehub (Cube hub) and it need to be unscrew from the non drive side and its terribly tighten. I´ve seen some freehubs that that pop out after removing the wheel. do you have recomendations of such hubs? the ones that i can easily remove the freehub, clean, etc? thanks
I can't quite tell if the bearing puller collet, I think you called it, is just expanding against the inner ring of the bearing or is it actually catching on to the bottom edge of the bearing ring? In my Hub there is no space between the bearing ring and the sleeve separating the two bearings so I'm not sure what the bearing puller can actually grab onto. It's a very thin and tight joint between the sleeve and the bearing so I'm not sure how something could actually wedge in there and grab onto the bearing ring enough to pull it out. Maybe you could clarify what's going on in there?
Excellent video, two questions, 1. how were you able to deduce that the measurements taken equated to a 6902 bearing set? is there a chart that us mere mortals can use? 2. can you recommend a good after market bearing supplier, i have heard the NTN bearings are good? Thanks again, i really enjoy watching and learning..
Hi Alistair,
The quickest way is to search the size online. If you type into Google "Bearing 28x15x7", you'll get loads of results for 6902 bearings. However, the 6902 is the most common bearing, so I knew what it was.

I think this video is gonna be super helpful in helping me service my campy rear hub bearings. Liked and subbed!
One thing i noticed was what about the bearing remaining on the rear wheel axel after the hub is removed 3:18?
Any idea why Tactic Racing hubs use 3 bearings in the rear? At least that is my impression after looking at their spare parts list. Wonder if I'm also missing a bearing aside from the two 6803 NTN bearings i will place an order on...
Hi timtimzi,
That damage to the freehub body at 3:18 is known as cassette bite. It usually happens when the cassette isn't tightened enough, and therefore moves a bit.
Never stripped a Tactic hub, but you used to get a lot of hubs with a third bearing in the middle...... There was a reason for it, but I can't remember for the life of me why!!!
Hi John, have you done a video on cleaning and lubricating a freehub, I am keen to understand the debate between light grease and lubricant etc? Many thanks, Tim
Hi Tim, This is an interesting subject right now. Until relatively recently, the advice from wheel manufacturers was to use a small amount of high quality mineral oil. Take Mavic for example, they've always sold their own high quality mineral oil. But now we're seeing more and more that wheel manufacturers are recommending a light coating of grease over the pawls. HUNT being a fine example of this. Although pawl design has changed, the fundamental mechanism of a ratchet system of some type remains. So, if the technology hasn't changed, why are we doing it differently? Additionally, the freehub contains small delicate moving parts....... Is grease the best thing to use in a place like that? Saying that though, grease will do a better job of keeping moisture out. I don't know what the correct answer is. Personally, I use a small amount of mineral oil on each pawl...... Works for me.
@@ribblevalleycyclist thanks John, when you say mineral oil do you mean the same stuff as used in mineral oil hydraulic brakes?
Hi Tim,
No. Like the stuff you'd use on your chain. This is my go-to general purpose workshop oil:
Fenwicks All Conditions Chain Lube:
amzn.to/45ZDNqQ
I have a 15 x 28 x 7 millimeter sealed bearing that has failed catastrophically.
The inner-rings and ball-bearings fell out during disassembly, but the OUTER-ring only is still pressed inside the aluminum hub-shell.
Do you have a tutorial on how to remove a sealed-bearing OUTER-ring?
I'm guessing it must involve removing the opposite side bearing, and any axle sleeves, and then carefully reaching inside the hub-shell from the opposite side with some type of long punch, and gradually tap-tap-tapping the OUTER-ring out, if there is any surface available on which to make contact with a bunch.
Tks.
I would always advise, where possible, to pull the thing out straight. Do you have a puller set like the one I use? If so, just switch to a larger puller collet. I think it goes upto 25mm, so it may well grab the inside of that 28mm. If not, then yes, get the other side out, then tap out from the other side.
Good luck with it, and let me know how you get on.
Jon
Would you ever go back to cup and cone? I just bought the FH-QC500-MS and the HB-QC400 Shimano cartridge hubs and I worried about how good they are. Any experience?
A good question, one I've not considered, until now. Yes, I would. C&C does require a little more maintenance, but as a person that is well-equipped for that, I don't really mind. I also get some pleasure out of the simplicity that C&C gives. You also don't need a load of specialist tools, just a couple of cone spanners. Up until recently, Shimano only used C&C. So, those Dura Ace wheels you'd see on bikes winning The Tour...... C&C.
Brilliant. One problem with a couple of my hubs is that they're old (orange) Easton hubs and its made of Swiss cheese. By the time I need to the bearings, the splines are so deeply notched, there's not much life left. BTW, does every bearing have an inside face vs an outside face? Some the seals are the same colour on both sides
Hi Ric,
Orange = Full Seal. A tight seal that prevents water getting inside the bearing
Black = Non Contact Seal. Seal isn't a tight fit, so water can get out.
Sometimes they use both. Full seal on the outside to stop water getting in. Black on the inside to let it out if it does get in.
@@ribblevalleycyclist great thank you!
Hey Jon could you do some mountain bike videos?
Oh no, far too muddy for me 🤣🤣🤣🤣. Joking aside, to be honest Steve, I rarely get them in, as it's not something I usually deal with.
Interesting. I have to remove freshly pressed press fit BB cups, somehow I broke the sleeve inside. Wacking them out doesn't work, I'm scared to bang too hard. Can I use a tool like that to pull one of the cups out? I have a 3d printer and a BB press fit tool, so in principle i can design and print anything
This is the tool I use to knock out press fit BB's:
amzn.to/3OMsw7A
I did the same thing. The FSA BB has a sleeve it two parts so it's much easier to fit than the Shimano single sleeve.
Hi mate great vid just wondering if the press/puller sets would work with press fit bottom brackets?
Hi Ozzy, Press will, puller won’t, it’s too small. Think it’s maximum is 25mm
Ah gotcha thanks for reply have you got a link for the tool you use?much appreciated
@ozzzybeno889 Hi, this is the press I use:
amzn.to/3LI0oRC
Hi mate I meant the puller for bottom bracket!
@@ozzzybeno889 Hi ,
If it’s a press-fit BB, you don’t tend to use a puller. They’re usually knocked out from the other side using a tool like this:
amzn.to/3PpfTja
Obviously though, double check your bearing type.
Where can you find the appropriate bearing number for the size bearing you just measured? Is there a manual or industry guide?
The bearing number is normally on the seal
Agree with Aperfectcircle. However, it's always worth having the ability to measure, as the seal can corrode, or with some bearings, it's written around the outside edge, which can wear.
Google your hub bearing size
Good video Jon, for a man of a certain age this is 'bike porn' at its finest...it features a bike, a workshop, bike tools...what's not to like! 😉👍
Hi Pete, Glad you liked it. I'm thinking of doing a wheel bearing one too...... But I'll just have background music when I do the work.
Hi can you tell me what degreaser you have used?
Hi, Sorry for the late reply. It's this one:

Thanks,

Currently unavailable for both tool sets.
The same press set is available on eBay for £10 less
The links I shared are UK links, and they're still showing in stock. Worth pasting the product description into the search. But if there is a new one on eBay for £10, I'd go for it. I'd buy a spare one for that money!!!!
@@ribblevalleycyclist I think he meant the press is £10 less than the one in your link, not for £10. If they were £10, I'd buy all their stock and sell them on for £20 each!
@@jonford6119 Oh yeah, I see that now. Was a long day yesterday!!!! Would be good if they were £10 though 🤣
The proper way to do it.... Ground down screwdriver, same diameter socket and hammer here.... 👌 Oh and a nice piece of timber to rest the freehub body on 😎 and i meant your method the proper way 👍
If I said I’d never used a socket and a hammer to deal with a stubborn bearing, I’d be lying 🤥 😂
@@ribblevalleycyclist Nice one fella... Keep the DIY coming... Great content pal 👌
Good video b Ulisses bad
What if you dont have these tools? how can you remove those 2 bearings? ua-cam.com/video/QIbjsCwOr9c/v-deo.html
There are many hacks out there. It's down to patience, your freehub type and luck as to whether you can get them to work. If you're doing lots of bike DIY, then it's good to own these tools, because you'll use them on other jobs. If you're not, then you'll just need to buy a new freehub.
I wish you didn't skip tightening the puller and tightening the press. So I could see how much pressure you use. You skip the last few seconds on both of those with the skip editing.
Sorry Logan, it’s a balance between keeping it short, whilst keeping it informative. Neither need a great deal of force……. if I had to guesstimate, less than 3-4nm. Or less than a stem bolt.
