- It's essential that your free hub body is in good condition in order to get maximum efficiency out of your drivetrain! If your springs and pawls are clogged with dirt, grit or heavy grease, the life expectancy and condition of your free hub will deteriorate rapidly. So here's how to strip, clean, lubricate and reassemble your free hub body!

As Doddy says in this video, you don't need to do a full hub service in order to make sure that your free hub is running in good order. You just need to clean the springs and pawls with a small amount of de-greaser before re-lubricating with some thin chain lube. You can then re-assemble your hub and you should instantly hear and feel the difference!

Global Mountain Bike Network frame pivot bearing service and replacement
I really should start watching these BEFORE I start the job.
I never thought you could just use oil instead of grease, thanks!!
Nice video 😊 I always use a wooden toothpick to get into those small areas plus it won't scratch anything.
Great practice!
T4 Tips & Guides man after me own heart ha ha
Doddy's maintenance vids are awesome.
Still refer back to this video to do a free hub service. Was having serious issues with a completely sticking engagement. 1 hour service with complete clean down of internals & cassette. It's like a new bike!! Cheers Doddy.
Nice one adam! Good work 🤘
Iv done so much work on my bikes along with my friends bikes with the help of your guys “how too” videos. Thanks for all the tips and keep the videos coming!
Top video, even if people don't want to work on their bike themselves it's always good to have an idea what's going on with a bike and that jobs like this do need to be done from time to time. You just know Doddy loves taking his bike apart as much as he likes riding it.
I love these kinds of videos, helping people to keep their bikes running in better working order and showing them that a lot of maintenance can be done at home with minimal tools and equipment and just a bit of patience and of course the important know how. Saves money and teaches people about how their bikes work! Keep up the good work, lots of thanks to Doddy and the whole GMBN team!!
very well done! keept it up with the advanced level maintenance videos! very nice to have these kind of tutorials, especially for riders on a budget like me, who can work a bike, but are a little intimidated by all the fancy mtb tech
Just rebuilt mine with thick grease. Damn. Strip down again I guess. Good thing I enjoy tinkering.
I just did that 😡 learn something everyday 🤷 Now need to get some proper oil.
@@mikeburgh3956 it's quite obvious once you see the pawls isn't it!
Thanks for the vid, just did this to my friends broken freehub and it works now!
Very helpful & comprehensive tutorial, thank you.
After watching this I was able to disassemble & clean cassette & free hub without too much stress. Cheers!
My first experience with the inside of a freehub was like this; I was riding my brand new Trek Remedy that came with a dork disk. That disk came loose and annyoed the crap of me so I decided to remove it on-trail. I did'nt have a knife or a cutter, so I used a sharp rock to try to cut it off. Suddenly the whole dork disc came loose, and so did the freehub with all its pawls and spring, littered on the muddy, sandy trail. I had never imagined to see such delicate parts on my bike! Surely I thought i was fcked! Some of the pawl springs was also strecthed. By some mircaly using a tiny stick to guide the springs and pawls back(yes i found all the springs and pawls), I was able to reassemble it and the hub worked for the next 3-4 years i had the bike!
Toothpicks work great to clean small nooks they have a nice small end and wont scratch anything
Good one again :-) Although should've read "pawl" instead of "pull" ;-) Also I wouldn't use oil in the freehub but rather a specific freehub grease.
You're right it is 'pawls.' We wrote pawls in the description but missed the ones on the video! A chain lube is common practice, alternatively a thin grease, spread very thinly with something like a paintbrush works too.
@@gmbn does it matter if the chain lube is wet or dry?
@@andylloyd7651 i also wanter to ask this. is the chain oil seal friendly? anyway i would use a wet lube as the dry one is.. dry :))
@@gmbnso would park tool PPL-1 be to thick?
I missed the part of degreasing and re-greasing te bearings in the body and the wheel as well. As I'm a mechanic this is a daily job for me😆 Love your vids guys!!
Thanks Dod for the video. It gave me confidence to clean my hub. I eventually discovered only 2 teeth/levers were working, the other two were just stuck and useless. It sounds way better now !
Best maintenance video in a while, great job explaining how to do this task at home!
Great video! Thanks! But what a PITA! I’m going to stick with DT Swiss star ratchets. I don’t care if they have crappy engagement. Super reliable and easy to service.
Could you do a video on how to replace freehub bearings?
Thanks for sharing this free hub maintenance 🙂👍
Now i know why my hub get silent...thank you so much #GMBN
''Springs can be a real pain when they fly out'' . YUP, THEY REALLY ARE. Especially if you are trying to service your hub outside. :)
you guys should do some more dirt jump related videos too
We're working on it Ollie 86 :) Blake will be back on the jump bike soon!
Good job Doddy! Good info. I'm getting ready to do the same thing to my I9 hubs this winter! Cheers.
Hi what kind of lube did you use? Is it the lube for the chain? And is it wet or dry lube? Thank you
It looked like some kind of WD40 oil.
Its nice when u order a new set of wheels and they come with shitloads of thick grease in them hubs so you have to take it down to just cleanse some of it to make the best out of it.. happened twice for me so far
Oh Doddy! Thanks for this! I’ve recently cleaned up my freewheel on my DTSwiss hub. Thought I’d done a good job as I’d got rid of that loud click which I find annoying. It works ok though. Guess I’ll be taking the wheel off and starting again, this time without a ton of grease!
A lot of grease will make it a bit quieter yes, but the trade off is that more grease will hold on to more dirt. On the other hand, not enough lubricant will promote excessive wear (and a very loud noise!). There's a happy middle ground as demonstrated here :)
sounds good to me but what kind of lube are you guys using? chain lube?
Yup, all condition chain lube works a treat!
I use grease on my Hope freehub as that's what they recommend. Didn't think using lube was an option
20noups i actually used motor oil but i believe it leaked out so im gonna use some thick chain lube
And when in doubt or you lack the tools like me pay a local bike shop to do it for me
Sound advice! If you're unsure and don't want to attempt it yourself, then get a professional to do so!
Global Mountain Bike Network it just makes sense my trek fx uses a mtb group set and i did have to get the freehub replaced i like a goof ball blasted the grease out of it 89 bucks later so far so good
Never trust someone to do a job you can do yourself.
Well I wanna go work in a bikeshop so I use your vids and just wing it hoping for the best. Worst case scenario I use 1 of my other bikes to commute whilst I wait on parts for the 1 I messed up. You guys mainly with your videos inspired me to get and maintain my own bike, now me trying to make it my profession.
nicholas danca Your on money on that one dude couldn't take the chance and stuff it up ,that would mean no weekend ride (NO WAY)
And then there's me who filled the whole ratchet system thick with grease, lmao thanks for some useful information :D
Ive been using vasseline for my hub my entire life, no trouble yet...
Awesome video , just got back from a ride and my chain would slip . I know it’s not the gears or the chain cuz I replaced them last October ( we have long winters here so I haven’t been riding much ) . So I’m thinking it’s the free hub as soon as I got a few minutes I’ll take it apart to see what’s happening.
Is that Lance Bass from N’Sync?!
It looks like him lol
Loved the video!
Did you guys put the rubber rat in the shop yet? Looked for it today on the chai keeper video but didn't spot him.
Think he's somewhere in the GCN Show Set right now! Keep an eye out for him this evening!
Enlighten me Doddy
Is that chain lube for the pauls?
For springs & pawls it looks like he did. I would definitely use for springs, and a thin hub grease for ratchet
I've noticed you did not put some grease on the pawls and ratchet,you put lube instead.I am a little bit confused because here in my country they said putting grease on the pawls and ratchet is very important.
Pedantic, but pretty sure it's "pawl" not "pull". Otherwise helpful video as ever chaps :)
I noticed that too. I wonder if it is just an American vs British difference.
Pretty sure that's just a pronunciation / accent thing, not a different word
Just an honest mistake I expect - it should definitely be pawl en.oxforddictionaries.com/definition/pawl
You're right guys it is 'pawls.' We wrote pawls in the description but missed the ones on the video! Oops 😇
Can you do a video on how to fix loose down tube inserts for brake hose clamps? I had to replace one and the screw went in a little tight and now the insert spins.
Great video. Got loads of tips thanks
Can you guys Do some more cheap product videos to make your bike cooler and better but really enjoy only just started watching and am enjoying heaps and I have fixed so much on my bike from your videos love them heaps keep them going:)
4:35 - "Although it's quite clean, it's quite gunky in there" - errr... 😉😀
👌interesting video, would this be a similar procedure, with a every know an then slipping freehub body ?
Many thanks.
Good video, wouldn't you clean and grease the axle though?
Awesome, very helpful.
Great video. Very helpful.
Please bear with me, its a rather long piece, sorry about that. l just started to write and then it happened.
Thanks for the videos, l enjoy them immensely, honestly other than cleaning the bike and a few very idiot proof repairs l have hardly ever done anything for a number of reasons.
One of them is that where l currently am, the bike shops are very accommodating, l can go in for a tune up anytime and its free. This l realise is too good to be true.
The other reason is that l do not have the right tools at the moment, which brings me to another point, what would you recommend for a home mechanic to be able to do just about everything which a normal person can do. By normal l mean someone who in his entire life has never had to do anything manual other than maybe a bit of forced gardening as a child and nothing worse and since l work in a very untechnical environment, l have very little chance of learning.
The last reason for me is this, your videos seem to be aimed at someone who already has some experience with this sort of thing. Try to remember that a bike is a very special tool for some of us and very expensive mine is a hardtail so in some ways its basic but l cannot imagine how l would feel if l muck it up. So l hope when you make videos you could have two versions the long one where you show each step so that people like me can see it all. l have written before about this where l said basically that too much is editted out. l know others are seasoned home mechanics so they do not need the step by step guide some of need. For instance, on this video you never mentioned the tools needed for the job, something l remember used to be part of the old videos.
So for the reasons stated above l hardly ever tinker with my bike. However, next month hopefully, l will be away for a few months with bike in tow. l am thinking l may leave the bike and get a new one upon my return. Where l am going there are very few bike shops and any small job is very expensive so therefore l will definitely need to be able to do most of my own servicing when l am there and should l decide to leave my bike. So you can imagine how much l value your videos.l realise some jobs are better suited to pros but for those where a well prepared home mechanic, with the right tools and information, l want to do those by myself or at least have the option to. However, please try to make them as simple as possible and do not cut out anything and have two versions to cater for all your fans. l am even thinking of downloading a few of them to take with me, thats how much l think they are useful.
Talking of travelling, l am aware of bike bags or boxes, but which is best l will need to travel across two continents and about three stops before l get home, so l am rather concerned about the state in which my beloved steed will be when l get home. l am flying but l will need to change planes along the way. So can you recommend a box or number based on price, strength and availability. My bike is a 2014 hardtail and l think it is a medium. l may need to use this box or case more because l foresee a lot of travel at home and in the future involving this or other bikes, so please do note that. Have seen the videos about boxes verses specialist cases and the issue of soft and hard cases but l am still not sure which is the way forward so your opinion in this would be highly valued as l suppose you lot do a fair bit of travelling so should be well versed in that sort of thing.
One last question, are there any courses like weekend or evenings for bike maintenance you know about? l would be willing to join, l am unfortunately not in the UK but it is good to know all the same and do the big Taiwanese brands offer any, l have a Merida. l mean a residential sort of thing over a week or a few months enabling one to service, assemble bikes. l sometimes think of eventually running my own bike shop but l am always worry about that aspect, sellling could be easy but the maintenance and upgrade section could be another issue. ln as far as l know where l am from there are no locally available courses.
Anyway l have said a lot l hope you can take the time to answer the questions raised. Sorry once again for the length, l tend to ramble.
Hi ddx ddx,
Okay, so this really is all the steps involved in this process with this hub! This video moves too fast for anyone to carry out these steps alongside it! If you're using this as a work along then watch a tiny bit, hit the pause button, carry out those steps and continue. This applies to all of our mechanical videos. Nothing essential in the process is skipped out, glossed over or removed in the editing process.
Our mechanicals are aimed to be followed by everybody at a comprehensive beginner level. Logically, a comprehensive beginner mechanic would not go straight in at servicing a freehub body. Start with a simpler subject such as fitment/removal of various parts, safety checks or indexing gears from our mechanical playlist: gmbn.eu/mtbmaintenance
Start small, work up to bigger jobs, if you enjoy it begin to get more tools for different jobs. If you're ever unsure or think you've gone wrong then have a professional cast an eye over it. There are a huge variety of maintenance courses all over the world, so best check in your local area with an online search or an ask around local bike shops.
As for travelling we use bike bags, soft shell with a rigid skeleton interior. We understand that this isn't for everybody due to the expense involved in them, but as we travel frequently with our bikes they are considered an investment. A good sturdy box reinforced with an entire roll of gorilla tape will do you well, provided you include a good amount of protective packing on the inside. Check out this video from the archives for how to pack your bike in a box gmbn.eu/flyyourbike. Hope that covers everything!
Thanks a lot for the reply, you said a lot of useful things, l will try to do as advised. hopefully l will be able to share some good news regarding progress as a home mechanic.
That's all very well, but what about the EL269 (FSA) type of freehub where it is all internal?
That hub doesn't even look like it needs a cleaning/service imho.
How often should I do this?
Same video on a non XD hub would be nice too.
Although there was small amounts of sticky grease inside the springs and pawls that would slow the movement down, you're right in saying there wasn't as much dirt as should be expected in there. We'd suggest doing this every 3-4 months depending on ride time. Not super regularly!
Any recommendations on a silent freehub of making my existing one more quiet ?
Thanks in advance
Would a spray lubricant applied to the chain with minimal application, could that ifiltrate the freehub to dilute the grease applied to the freehub at manufacture? In other words, how easy is it for the freehub to be infected by external contaminants?
Hi Doddy, I have a 2019 Scott Genius 960. I want to upgrade my free hub but not sure what I can get for this, I love the sound of the Hope hubs can you help? Thanks
awesome video. is there a video about replacing bearings? is it hard to take them out and put them back? do I need a special tool? I want to replace bearings in Mustang Pro 4 Boost 148 and my local shop told me it will take 2 weeks. I don't want to wait and want to try to do it myself. any advice? how hard is it? I am pretty good with my hands. I did 50 hour service on my rear shock couple days ago.
Realy usefull... thanks a lot.
Can you do a video about Trek remedy 7?
What are the tools required to open a free hub ? Using Polygon Premier 5
why does the freehub come stock from the manufacturer with thicker grease in there?
Thanks for this tutorial... but, as you know, there are a lot of differents hubs. I need a tutorial of a sram/btwin one that have the freewheel not so free (i'm italian, i explain as i can: it tents to rotate with the wheel when i stop move pedals, so it tent to drive the chain and the chainrings). Probably it is only very dirty and sticky but i don't understand how to open it. It is a sealed bearing B'Twin hub with a 10 speed body for Sram X7, original part of a RockRider 720s my2016, probably. Thanks, anyway :-)
"simple and easy", well for this specific hub. what about the hubs that need the unicorn 15mm hex wrench in order to remove the freehub? or such freehubs are suposed to not be service? cheers
Parktool Set Tools, Are spensive
Is this the reason my crank is hit 'n' miss engaging? Only had the bike (Whyte T130 CRS) 12 months, last couple of rides the crank isn't engaging
So no grease on pawls or springs correct?? Just oil? Im trying to see what that WD40 oil is? Special kind? Ty
why do the freehubs com stock from the manufacturer with the thick grease in there?
I was wondering what kinds of lube Greece and oil I should get and how many different kinds #askgnbm
I just want to ask a question... Is it real that the CRIMSON HUBS like CRIMSON CLAW, CRIMSON GEAR is Really Made in CANADA? Because here in the Philippines, Some of the Seller of this hubs telling that its Made in CANADA... thanks and Please Enlightened me. 😊👍
Hi Doddy, nice video! I have a Solon qr, can you let me know how to open the freehub body? It's different with novatec that need 2 L/allen keys to open it. Thanks in advance :)
My cassette along with hub comes out and I have to nip it in with frame to keep it there , is it completely gone ?
After cleaning by bike, the hub got quieter. I have to relube it I guess. Am I right?
Is a hub from a 26 inch wheel the same as one from a 27.5inch wheel?
I just got new giant trance bike and the free hub has pretty loud noise when the wheel is rolling without pedalling.... Anyway to make it quieter?
Sir i have a rear hub that slips when i pedal and im not going anywhere. Do i need to replace it or service the hub? Thank you.
Can I use thin grease than low viscocity oil on the ratchet?
What oil are you using?
When I swap out my XD hubs for bystander Shimano ones can I interchange the paws from my XD Hub to my Shimano hub so that I can have that ratcheting noise of the XD hub. Thanks for the video let me know if you happened to know I really appreciate it
Hi GMBN, can you do Freehub service for Hope Pro 4?.. in a bit details.. thanks
Almost the exact same thing. Also go to Hope and see dwgs.
www.hopetech.com/product/pro-4-rear-hub/#tech
Do you use wet or dry chain lube?
Dry to all condition chain lube, wet specific can be a bit sticky depending on the brand.
Thanks!
Can I wash my knee pads (poc vpd 2.0) in the washing machine? And yes would there be any special things to keep in mind settings or anything
Can you take out the inserts? I can with mine (not poc vpd's), and then put the fabric part in the washing machine (40 degrees, easy washing without spin, no dryer). Shouldn't harm them more than rain and mud.
I have bearings in my cassette on the hub part
I am going into the 3rd week waiting for a delivery for a Shimano free hub for my 2020 Specialized Turbo Levo . They say in it shipping but can't say when it will arrive . Summer flying by and I can't ride. The number on mine is fh-mt510-b . Would any of the other models be compatible ? I need the 28 hole version.
@gmbn my hope pro 2 evo feehub body is gouded. Should I replace it or file the highs down and keep riding?
Thanks for the great video! What chain lube you suggest to use, dry or wet?
I got the e*13 hub and there is a good amount of thick substance, not sure what to use if I wipe it all out.
Will this stop the axle being notchy when spun?
Worthy
Neither of hubs look or come apart anything like this and it's really frustrating
Hi all how about instead of using a screw driver to clean out the hard to reach bits use a toothpick/cocktail stick ???
If you use a tough one that doesn't break you should be fine
Yeah great shout! We were fresh out of cocktail sticks 😉
Can someone please tell me the answer to my question. I have a merida big nine 20 and I washed it and water must of got in the caset some how and now there's no clicking noise when I stop peddling I'm only 14 so is there anything I can do that could fix it.
I thought u need grease in the freehub. U can just use oil
What's the stand over height?
Do you know how to Remove the end cap of the cranck brothers cobalt hub?
#askgmbn I am having a hard time clearing jumps and doing manuals, after watching myself I need to pull back more. How do I gain the confidence to pull back further?
I use Muc-Off C3 ceramic lube premium dry on my chain. Would this be ok to use on the pawls? Thanks.
Hi
can i use mucoff chain oil in the hub?
i have a shimano deore xt hub...how do i get the two silver screws (i have to entighten first) off? do i need special tools to do that or can i also use a pliers to lock them up? (10mm x 135mm quick release)
(sry for my english...i´m from germany)
@gmbn just curious on what kind/brand of shop towels you use?
What oil is that? I have some shimano freehub grease will that do? Thanks
Yep that'll do, you just don't want to use too much!, just a smidge
Here in the Philippines they use grease for repacking the rear hub.
I have a big question about hub. I'm searching for a loudest hub so which hub is the loudest. Hope pro 4 or Industry 9 ??
Whichever has less grease in it! There's not much in it but Industry 9 might have it!
Oil not grease? I'll have to try that.
Yeah!, Couple dabs of all condition chain lube does the trick!
