Thanks for the great video. Changed my freehub body and lubricated...now as good as new. Would not have known how to go about it without this video, Thanks you.
Exactly the same hub that I have too much play in. Now Ive seen this I may aswell carry out the service whilst im sorting the problem out. Great vid thanks
1:55 just an Allen wrench even though the shape in the hub looks "special", it is just a allen wrench. My shimano was 10mm Allen. It take a wiggle then it fits perfectly!! Also a T55 torx works too.
The hub should have a small amount of play. when placed in bike QR clamp eliminates play for perfect adjustment. Use 2 9mm box wrenches and QR skewer to test adjustment. also insure drive side lockring is secure.
You've missed the main most important part of a hub service which is the repeated adjustments you need to make to cup and cone tightness with the cone wrenches, then mounting the wheel into the bike and checking rotation (without the brake rotor complicating things - another reason to take it off for this service), and then re-adjusting.
Brendan O'Meara do I understand your response correct that you need to check whether you have actually assembled in such a way that your wheel is in the centre of your frame again? Should it stick out on both sides similar distances?
Fantastic video. But I found out that "finger tightening" the bearing preload is tight until you install it on the bike and you can feel it being loose. I had to use a wrench and go ever so slightly PAST what your finger can do. It feels runn, but once you tighten down the securing nut it's fine.
There are basically two types of hubs. One where there is an industrial sealed bearing on each side and the other where there are balls like the Shimano XT. Just take it apart and see for yourself.
How often is it necessary to service your bike hubs? How would you know if they need servicing? All I can think of is if they do not spin well or maybe you hear some noise. I have an old road bike that I have never serviced the hubs and the wheels seem to spin fine. I just clean and squirt a little tri-flow lubricant around the hubs from time to time.
You should remove that rotor before doing this it can get messy and you might contaminate it. Not saying your couldn't do it without contaminating the rotor, its just more work making sure you don't than just taking it off and putting it back on. Also, you'll want to use a light weight grease like Slick honey to reduce rolling resistance.
Hi Daniel! is Phil Wood grease (comes in a green tube and grease is green) okay to use? See my other comment as the blow out of my M770 seems much more complex than this and I think to really overhaul it don't you have to completely take it apart?
@@mwj5368 hub bearings is a perfect use case for Phil Wood grease. As for a "complete overhaul" yes this video just shows how to do the hub bearing service. You can also service the freehub. Plenty of HG freehub body service vids that can walk you through that bit
It is a home made tool. Use translate button and find out more at our web site bikebook. si. Post is called CREATE YOUR TOOL FOR CHANGING SPROCKETS and it is under do it yourself category.
Very nice video. Some tech advice: when you tighten bolts the wrench's "teeth" should look the other way. I mean at 3:15. Rather than that i repeat very good and finally clear video.
This isn't freehub body, this is a video on how to overhaul and adjust a rear hub. The freehub body is the part that the cassette sits on- you may want to change the title as this is not accurate. Thanks!
If you want to remove the freehub body, and you don't have the special tool, use a 10mm allen key, but even that is too small. If you have any spare spokes lying around, get two of them, push them through and then push the allen key through. You will find a perfect fit and no slipage whatsoever.
Hi. You wouldn't be able to on a standard rear free wheel hub. Hope make a front wheel hub that can take special adaptors to go from 20mm down to 15mm. I had the same issue trying to convert my Scott 20mm thru hub to a 15mm thru hub to take new forks. In the end i purchased a new hub and rebuilt the wheel with it in. Good luck.
jose castillo i would definitely remove the rotor first. Just to prevent accidental scratches from the tools used in the process. No matter how cautious you are, one little slip and boom - new rotor time.
If you get good grease on the rotor brake cleaner won't always remove it and you may be screwed and have to replace the rotor so as a precaution is agree to take the disc off
Fantastic video, thank you very much. Nice and clear, what I like to see. No filming from 25 feet away so you can't see what's going on/hands obscuring things. Well done.
I find it a lot cheaper to use a good lump of butter instead of that grease although I have to service the bearing more often - say twice a month or so and sometimes there is a lot of rust in there
i have a hub xtr fhm 965, the problem is, sometimes it freewheel both side, i tried to put grease on my bearing both side and it did not help.. i think the problem is the hub body.. any suggestion? need help..
Casi bien faltó quitar los guardapolvos tanto del lado del disco con del lado de la criquera , luego faltó quitar el disco para su limpieza y descontaminación, y faltó desarmar la criquera o body para limpiar adentro , al menos es lo que hacemos en el taller así son los mantenimientos de las mazas sean Shimano o la marca que sean, de todos modos bien el vídeo, saludos desde Argentina.
2:56 "Loosely tighten. There should be no play at all". I and many disagree. There should be LITTLE play which is lately eliminated by compression forces caused by quick release. No play at all leads to premature wear of cones and balls.
yeah, from my 20 years of experience i think the same, to tight will destroy the cones very fast. note how this dude removes the cassette to clean and to put grease on the hub, why the hell one need to remove the cassette
Hey..... After some maintenance on the rear hub, well to be exact the cassette, the plastic disk that is behind the cassette started to rub against the cassette. So what do I do? Remove the plastic disk or put some grease down there. I really can't decide.
good video, I just put my bike in to bike shop to get my hub serviced as i didn't know how to do it my self. on a completely different topic, I just put a new cassette and chain on today and on the 8th gear whenever i put pressure on the on it the chain jumps/slips off only at a certain part of the chain, however all the other gears are perfect any ideas ?
Check your chain tension. Had a similar problem but on the front chainring. Culprit was my rear derailleur was getting stuck at some point and it wasn't tightening the chain enough. I had to open, clean and lubricate the clutch on my slx shadow plus derailleur. Problem seems to be gone for now.
At 3:20 you put on a rubber seal? I have 2016 rockhopper. I have followed the video, but don't have that part. It's clear water and can get in, so should there be one on my wheel? Appreciate your thoughts.
Does any one know how tight it has to be in 2.57, on the video it states 'Loosely tighten' ? does that mean just enough for their to be no play at all, but no tighter beyond that?
I had the same problem the other month ago. My freewheel makes a grinding sound and wobbles when coasting. When I opened it, even when not attached to the bike it was still grinding and was pretty hard to spin. I also discovered that my axle was bent. I just bought a new freewheel, axle and replaced the bearings now it's fixed.
Got a question: I have a next power x 26" mountain bike. It is my transportation and yesterday I replaced the bearings in the front axle and it will free spin forever but I tried the same with my rear hub as I already did the bottom bracket but the rear wheel spins foe about 20 seconds before stopping. On the cassette side of the hub are there any bearings that I can regressed and replace? I can't get the plastic(?) Thing that the cassette sits on. Any feedback please PM me thanks!
Not applicable to my rear wheel, there is a locknut that is holding the disc brake, and there is no space to insert the wrench. On the other, cassete side, there is also no space to insert the wrench.
It's rare that the music on stuff like this doesn't make me want to jam icepicks in my ears !! That was kinda groovy, it would probably make a good guitar backing track.
My pedals keep slipping (up to a full half revolution) and I'm told it could be my HUB. Im not 100%. Any tests etc i can do? or other problems this could be a symptom of, please?
He’s using 2 wrenches and grease... how hard is it to google something? You have the knowledge of the world at your fingertips. Don’t be a lazy ass, look that shit up and be at least somewhat self-sufficient.
what is the tool you are using to remove the sprocket cassette? and where can i get one lol! :) i have bought 3 different 'cassette removal tools' and none of them have fit my cassette, one being different in the way the teeth are arranged and the other is literally 1mm too big to fit. any idea's thx
its just a standard freewheel that came with the bike from halfords im gonna get a whole set of cassette removal tools for all makes lol then i know one will definitely work :P
you dont seem to understand... i wish to replace it myself, its easily done with the right tools and dont see why i should have to pay a tech when i can do it myself at home :)
Hes talking about the cassette? So one size fits all is some kind of wishful thinking or dream.. Its worth to buy the tools cause the bikeman will charge you at least $40 to do it for you and you cand ride the bike when your rear hub is eating itself
In wet conditions I would say once every couple of months. Dry conditions, once every year unless you start to hear grit or the wheel is a little loose (side to side).
Sounds like you broke the pawls of your freehub body, I broke a pawl on my hub and it did the same thing yours did. Remove the freehub body and replace it with a new one. Or, it may just be dirty, and making the pawls stick. Try cleaning it first. Good look!
Thank you for the clear presentation. So many of these types of videos look like they were filmed in a dungeon using a brick as a camera.
Thanks for the great video. Changed my freehub body and lubricated...now as good as new. Would not have known how to go about it without this video, Thanks you.
Removing the disk before is a good idea to prevent putting grease accidently on it.
Exactly the same hub that I have too much play in. Now Ive seen this I may aswell carry out the service whilst im sorting the problem out. Great vid thanks
1:55 just an Allen wrench even though the shape in the hub looks "special", it is just a allen wrench. My shimano was 10mm Allen. It take a wiggle then it fits perfectly!! Also a T55 torx works too.
My lemon random hub needed 7/16 inch Allen hex key which is 11mm

Brendan O'Meara do I understand your response correct that you need to check whether you have actually assembled in such a way that your wheel is in the centre of your frame again? Should it stick out on both sides similar distances?
I always use a strong magnet to get the balls outside the hub. Nothing ever gets lost!
Fantastic video. But I found out that "finger tightening" the bearing preload is tight until you install it on the bike and you can feel it being loose. I had to use a wrench and go ever so slightly PAST what your finger can do. It feels runn, but once you tighten down the securing nut it's fine.
@THEKINGBG1 look at 1:55 you should probably remove the freewheel body. There are some pins inside. Check them out and this should solve your problem.
There are basically two types of hubs. One where there is an industrial sealed bearing on each side and the other where there are balls like the Shimano XT. Just take it apart and see for yourself.

There are a few different tools, but this is the most common one on most modern bikes. Remove the wheel and you will see which one to use.
Nicely done video... Done that several weeks ago...same way as you did. Easy and fast to do...
You should remove that rotor before doing this it can get messy and you might contaminate it. Not saying your couldn't do it without contaminating the rotor, its just more work making sure you don't than just taking it off and putting it back on.

You can use a 10mm allen key to remove the freehub in the ones I've seen - no special tool needed
This was just what I needed to learn how to do thanks.I have always been scared to do this part lol this is a great video.
It is a home made tool. Use translate button and find out more at our web site bikebook. si. Post is called CREATE YOUR TOOL FOR CHANGING SPROCKETS and it is under do it yourself category.
@riskprocessor You should be fine with any bike grease if you do this regulary. I usually use White grease form Morotex which is lithium based.
Super tuto. Très clair, très efficace. Merci.
Very nice video.
Some tech advice: when you tighten bolts the wrench's "teeth" should look the other way.
I mean at 3:15.
Rather than that i repeat very good and finally clear video.
You are right, just enough that there is no play and then tighten a touch more.
Similarly @ 0.25 the adjustable jaws should be over the other way so the rigid jaw is taking most torque.
@minameise It is the Motorex Brake Cleaner.
This isn't freehub body, this is a video on how to overhaul and adjust a rear hub. The freehub body is the part that the cassette sits on- you may want to change the title as this is not accurate. Thanks!
Use a magnet to remove ball bearings. Much easier than turning your wheel upside down and trying to lever them out with a screwdriver.
You should remove the disc, to make sure it does not get any grease.
@i010524 Yes, you could but we clean everything at the end anyhow.
Why don't bikes have grease zerks on the axles? It would make greasing the bearings a lot quicker.
If you want to remove the freehub body, and you don't have the special tool, use a 10mm allen key, but even that is too small. If you have any spare spokes lying around, get two of them, push them through and then push the allen key through. You will find a perfect fit and no slipage whatsoever.
You can buy 14mm hex keys from Amazon.
Just finished doing this. Thank you!
great informative video...exactly what I was looking for...thanks a bunch...subscribed...greetings from Finland...
Good instructional film,but you should of torqued the half nut on the hub to 40 Newton meters as specified on the item.
You don't need a special tool to remove the freehub body, just a 10mm allen key.
On every Shimano free wheel?
Hi. You wouldn't be able to on a standard rear free wheel hub. Hope make a front wheel hub that can take special adaptors to go from 20mm down to 15mm. I had the same issue trying to convert my Scott 20mm thru hub to a 15mm thru hub to take new forks. In the end i purchased a new hub and rebuilt the wheel with it in. Good luck.
1:15 so 18 balls? those are from both sides right?
Thanks for the guide, it just helped me replace my bearings.
Fun times. I do this every other day @ work. Once you get the hang of it it's a breeze lol.
Nice guide, is going to be helpful this weekend, and I didn't mind the music whatsoever
Mmmmmm....you should remove the rotor before. Not only to prevent any bending but, to prevent any grease on it.
well that's why he cleaned it at the end, no need to do that if you're cautious.
Diego DIEGO No need to remove the rotor at all bud. Just clean it at the end like in the video
jose castillo i would definitely remove the rotor first. Just to prevent accidental scratches from the tools used in the process. No matter how cautious you are, one little slip and boom - new rotor time.
Little Scratch
If you get good grease on the rotor brake cleaner won't always remove it and you may be screwed and have to replace the rotor so as a precaution is agree to take the disc off
Fantastic video, thank you very much.
Nice and clear, what I like to see. No filming from 25 feet away so you can't see what's going on/hands obscuring things.
Well done.
Thanks for the useful video! Does it matter what year XT hub it is or has shimano kept all XT rear hubs the same for servicing?
hello buddy! i have downloaded this video. I am trying to learn the basics of fixing bikes. and thank you for your video.
Park Tool Cone Wrenches SCW-15 (for cone) and SCW-17 (for lock-nut) i believe.
I find it a lot cheaper to use a good lump of butter instead of that grease although I have to service the bearing more often - say twice a month or so and sometimes there is a lot of rust in there
HAHAHA :)

most of the time the cassette covers the inner nut on the axle. I usually cant get it off with the lockring on.

can you make this freehub body service tutorial also?
hi there, great video.
quick question, the grease you are using is it copper or lithium based?
good video, I just put my bike in to bike shop to get my hub serviced as i didn't know how to do it my self. on a completely different topic, I just put a new cassette and chain on today and on the 8th gear whenever i put pressure on the on it the chain jumps/slips off only at a certain part of the chain, however all the other gears are perfect any ideas ?

that spray and one that you used in the brake rotor
Yes kapalkilayz you need a new free hub body. Lubrication does not help once it he pawls have failed to catch.
Thanks for the vid enjoyed! I normally take off the rotor first to stop it being bent. Pain to straighten true!
How do you adjust the nut on the freewheel side, is it supposed to be loose?
it is possible to put too much grease in t here?
you can just use a 10 or 12 mm allen key to remove the hub.
Thanks for a clear video.
What model/made is that chain whip with spring ?
I like it !
How many ball bearings were there?
How often to you recommend cleaning and regreasing hubs in terms of miles? thanks

lol you know the answer replace the lot of it.. Its worth it for such little cost..
Thank you. You just saved my wheel!!
I know this is old, but does anyone know if this hub is compatible with newer 12spd cassettes?
Is a little play on the rear wheel ok I know I can't tighten axle all the way.
Got a question: I have a next power x 26" mountain bike. It is my transportation and yesterday I replaced the bearings in the front axle and it will free spin forever but I tried the same with my rear hub as I already did the bottom bracket but the rear wheel spins foe about 20 seconds before stopping.

what sized thin wrenches does one need for this?
It's rare that the music on stuff like this doesn't make me want to jam icepicks in my ears !! That was kinda groovy, it would probably make a good guitar backing track.
What was he spraying on the brake rotor?
if the inside cone?-cup? get problem then is replaceable?
if yes, how?
if no.......
My pedals keep slipping (up to a full half revolution) and I'm told it could be my HUB. Im not 100%. Any tests etc i can do? or other problems this could be a symptom of, please?
thanks for the help! loving the music as well!
Tuto is good....but...1st of all, always take out disk to avoid to put grease on it or to twist it...just my advice
What about the outer bearing on the other side of the wheel,that's the one I needed to change.figures,no help.
very good, however you need to give a bit of info on what you're actually doing. You need to explain to novices what tools etc your using.
Why?
Because not everyone knows what tools to use.
I expect you posted it to help fellow cyclists? 😪 why are you 'doing' what your doing?!
Don't overtighten.
He’s using 2 wrenches and grease... how hard is it to google something? You have the knowledge of the world at your fingertips. Don’t be a lazy ass, look that shit up and be at least somewhat self-sufficient.
Thanks, would the same principle apply when servicing front hub, in particular I have the Shimano Deore XT Disc HB-M756

one size fits all. It's only a bike chain that grips onto the teeth.
Hes talking about the cassette? So one size fits all is some kind of wishful thinking or dream.. Its worth to buy the tools cause the bikeman will charge you at least $40 to do it for you and you cand ride the bike when your rear hub is eating itself
Best to use new ball-bearings in case of wear not visible to the naked eye.
bearing ball replace with new one?
يصير افتح المكينة الخلفية بدون أدوات تشتريها يعني يدوية
Just bought a set of wheels with these XT hubs. I don't care for them but it was a deal. How often is this needed?
In wet conditions I would say once every couple of months. Dry conditions, once every year unless you start to hear grit or the wheel is a little loose (side to side).
Get some sealed hubs as soon as :)
Anyone know what type of lube to use on the ball berings?
Sounds like you broke the pawls of your freehub body, I broke a pawl on my hub and it did the same thing yours did. Remove the freehub body and replace it with a new one. Or, it may just be dirty, and making the pawls stick. Try cleaning it first. Good look!
*ok i gotta admit thats a fancy ass chain whip*
What make of chain whip are you using to remove the cassette?
Make doesn't matter just make sure it's the right speed for your chain
+matthew wyatt I was just asking for the make of the chain whip so I could buy the same.
You dont even need a chain whip if you have a spare chain & a screwdriver to hold it steady if you have the cassette tool.. just sayin!!
1:50 yeee that's how I clean my ears.
1:50
Where did you get the chain whip from
