Tricks To Remove & Service Shimano Deore Freehub Body. Clean, Grease, Assemble.

[@CharlesWalker-l2q]

Excellent stuff! The wheel against the wall, the 15mm hex key and the steel pipe for leverage. It got the job done for me and I am not sure I would have persevered without having seen your video. Thank you.

[@shakedydogshake]

I took an old socket, put it in the big old bench vice - and with an angle grinder, ground it with 2 notches to fit in the freehub to free up the guts. Great video!

[@DamnMyNickIsTaken]

This has helped me, thanks. I didn't have any tool available to remove the freehub body from the hub, so I just left it on there and disassembled it like that. It was cumbersome but still worked like a charm.

[@곰곰히-l1s]

Thanks to your detailed explanation video, I performed hub maintenance for the first time today. In fact, this is the first maintenance in 14 years. Now that I have learned it, I will maintain it once a year. Thank you again to mu Hub and Your.

[@Mersuharrastaja]

That first seal, witch you remove with screwdriver, I got good tip from Park Tool's video where Calvin Jones suggested use tyre lever instead screwdriver. And you can put back with right size socket.

[@th_js]

Yeah

[@BigerKuma]

Good video! I did part of this procedure, stopped before disasembling the freehub. My older Deore XT required a 10mm hex wrench. My hub wobbled on the wheel, so I tightened with the 10mm hex and put everything else back together.

[@Xesh001]

If you have to take the freehub body apart, then you can use the TB-1018 tool, from SuperB, to dismantle it. Alternatively you can use a Morningstar Freehub Injector so that you don't even have to dismantle it at all! Just use it with degreaser to flush out the old lube and dirt, let it sit for a while to dry out and then inject it with your choice of lube. I use a heavy oil, like gear box oil, which I've done now for about 20 years or so, with good results.

[@bushmancam]

great vid mate, i struggles for hours and dont wanna buy a new hub thank you for saving me a dollar

[@br4nd0n3ssketit8]

Get u here bro 😂👊🏼

[@robertpell6687]

Depends why you want to remove the freehub. If it is just a bit 'sticky' you probably do not need to remove it, but can get by with flooding it through with a solvent to wash out old grease, followed by a light oiling, with cleaning and regreasing the axle bearings.

[@S3thn3ss]

Thank you! I had to search for a while to find this video. Everything that comes up is either microspline or really old QR stuff.

[@execuline]

This is the best trick to remove a difficult freehub I found. Thanks

[@justbuggn]

This video was helpful.. thank you, I watch many of you videos and have leaned much. Keep up the awesome work 👍

[@john-di1bn]

it's recommended to use thick oil than grease when relubing the freehub because over time grease gets stiff and gummy and it slows down the pawl movement in the freehub, but you can use grease when you're putting back the bearing balls so it holds it and prevents it from rolling all over the place, or use silicone grease to lube the freehub(its much thinner and its safe for plastics and rubber) don't use magnetic screwdrivers to extract the bearing balls and then reusing it because it magnetizes the bearing balls thus preventing it to roll smoothly cheers

[@AlwyneAvinash]

If you don't find a 15mm Allen key, you can use a 15mm bolt welded to a right angled rod

[@jonienglish3231]

AMAZING DETAILED VIDEO !!!!!!!!!!!!!!!!! i have a ALEX ACE rear hub on my Cannondale Bad Boy 5 - Sram 11 hex socket , just added 10w-30 oil and took the rear seal and forced Automotive wheel bearing Grease .and reassembled

[@jasn959]

Thanks for the vid. Finally sorted my freewheel problem with a 15mm key.

[@stanislavmacak9755]

Konecne video, ktore mi super pomohlo. Dakujem.

[@ronaldo7martinez]

It looks more complicated to clean and maintain than the other budget hubs. I always prefer Shimano Deore for MTB, but I'm thinking now to get a Sealed Bearing type one now. :)

[@johnnydiamond1636]

You need a 12 mm star drive to remove from the wheel. I could not get the freewheel apart so soaked in petrol. Have it a tap on bench and pawls then worked. Final clean in thinners, soaked in container of engine oil and works perfectly.

[@cyrylski]

5:11 doing this without a special tool is the easiest way to damage the parts. In your video it seems easy because it's either brand new or you did it first offscreen. In real life this part will most likely be very hard to turn around within the freehub body. You usually open work hubs with seized parts, not the fresh new ones.

[@zdravo4]

Same goes for dissasembling of mobile phones on YT, all goes fantastic and when you try it you find that very complicated and tricky

[@frankunderwood8357]

A big torx driver also works if you don’t have a 15mm hex. If i remember correctly i used a t55

[@BhardwajAkshat]

Amazing detailed video thank you so much!! 15 mm hex allen key is veryt difficult to find and i bought an expensive one from park took for about £48 !! Used a seat post for longer leverage!! Thank you for the tips!! But I can't find a two tooth cup removal tool which is about 25-26 mm inner diameter ! I bought a Unior Suntour 1670.2/4 which is smaller in diameter and doesn't fit the two teeth. The cup is stuck in the freehub.

[@felixjackson2670]

Totally excellent. Thank you. Have a friends bike for service. Freehub needs stripping.

I find the attitude echoed in many of these posts, "but it's so cheap to throw it in the landfill and buy a new one and I don't have to learn or do nearly anything just buy and waste", very disheartening. I believe it was H.G. Wells who said;"Every time I see an adult on a bicycle, I no longer despair for the future of the human race ". I can assure you it is not "you" he is talking about.

[@clentmichaeldevera777]

Thank you Sir!! Your video tutorial is a big help

[@irvanfjb7962]

Unless the freehub body has play, all I ussually do is just immerse it in thick silicon oil and keep it for a night to let excess oil go. It is much easier procedure and last years before you need to run the procedure again.

[@demmini]

To install the seal I`m using flank socket applicable by diameter. Just put flank socket above of seal and easialy pushing it by hand.

[@nayeemrahman8219]

It's 37 and 35 balls. Your one ball moves to other side. And I just came here out of curiosity because of the hassle this version of shimano hub gave me while working! I have never seen this level of stubborn hub and that weather seal is excellent for riding but terrible to service! i had to take multiple attempts just because that seal hampers everything. After each attempt i had to reorganize those balls because they shifts and falls to weird places like spring grove, seal grove etc. And the way you install those two springs is not right. look carefully in the gap after 4 pawls you would see start/end juncture for springs. when you slide your springs there all on a sudden those springs recessed in that channel.

[@adipe3217]

you should always separate balls (those 38+34) and not mix them - when you take them out and put them back in - as they will not have the same size but eventually wear a bit so the size will differ from one side to the other. i am talking fractions of a micron but it does matter. take notice that good quality grease can act as a polishing agent (due to the additives) whenever direct contact of metal to metal would occur (mixed lubrication, not boundary, not hydrodynamic) so that they would have even smaller grade then when new. so, the balls will be worn a bit (not that you see it) and they should wear down evenly on one side but not in the same amount as to the other side.

[@veaceslavpascaru7294]

Nice video! Thaks a lot! Do you know the size (diameter) of the bearigs? Mine need replacing

[@BhardwajAkshat]

[@bananadaily2176]

Hi I love this channel

[@TheFixten]

I was for a vid with same hub as mine, finally the same Merida wheel, the whole thing is the same 🥳

[@MrMORITU]

I never put grease where the engager are located, only a dips of a nice oil, I use motorex CNC spindle oil, itc vgc 46. Work for me, on the opposite side behind the rubber in my case, I put a lot of thick grease as a preventative action.

[@theadventurebiker]

Good video, and great info here. But I'm not really sure this service is absolutely needed on Shimano freehubs. I've been running mostly Shimano hubs in my 21+ years of riding and have never had a single problem with any of them, except for a broken front axle on one occasion. I've taken Shimano freehubs apart before just for the heck of it but not because they needed any kind of service or repair. My current bike has XTR wheels/hubs which are about 5 years old and have over 25k miles and I've never even adjusted the bearings, much less remove the axles etc and they still work like new. In my opinion Shimano hubs are best left alone and will last a VERY long time without any problems. Which is a *LOT* more than I can say about some other brands for the few times that I've tried them.

[@theadventurebiker]

I also have a tandem MTB with a Shimano FH-RM30 rear hub (basically one of their lower-end hubs, and not tandem-specific). We've been riding it for a year now and it has over 2000 miles and works as good as new with zero maintenance.

[@HansensUniverseT-A]

I can testify, I've ridden my Surly Pugsley fatbike for about 7 years now, all year around, it's my daily rider and my choice for long hauls, it's still on the same Shimano freehub after doing over 40K km which is impressive, it's been abused a lot.

[@alteragnostik]

How would I understand if I tighten with correct torque the locknut which holds freehub body brearing together? The locknut which is also acts as a cone. You tighten it on 14:05 In my case I either get some weird axial movement/play in the entire freehub body (like if it's undertightened), or else I think I ovethight them. But the small play is always there.

[@brendancreaner9425]

SHIMS - there are 3 shown in the video. Remove one of the thin ones and check again for the end-play. If still there, remove the other thin one. It's unlikely that you'd have so much play that the thick one should be removed. The body should be fully tightened together as it should be screwed-down on the shims - NOT on the bearing-balls.

[@MikeTheGuy33]

I did not count the bearings but mine has a little gap too. It is normal i think because these items nt servicable parts. when try to fill gaps with bearings, it did not spin nicely. Thanks

Is a microspline swap available for this hub?

[@akachillywilly]

u can make ur own tool with a 21mm or a 13/16 socket to remove this cap

[@8noctus8]

What if the bolt doesn’t turn even using a pipe for leverage? 😞

[@Bugby]

Use a longer pipe. Unscrew that bolt after the inner one (the tool+socket cost 10€ and the screw thread is inverted)

[@alutious]

when putting the freehub back on, the nut that holds it on, that the axle goes through... is this hand tightened, tight enough without play but not too tight?

[@redtobertshateshandles]

None of these videos address that point, and it's the most important information. All the rest you can figure out yourself.

[@brendancreaner9425]

It should be fully tightened (though I don't have a torque-spec), as it's screwed-in metal-to-metal - NOT resting on the bearing-balls.

It depends... if you have the ratchet system like the dt 240s that it will only work with this special thin grease hitch looks like oil. The pawl system is a bit different ... but yep also here is the special thin grease the best choice. A thin layer of grease will also work. Less is more here 😂

[@th_js]

[@ryantucker6702]

Hi I would probably do this as I'm into not buying new unless totally unavoidable. Most manufacturers recommend not using grease only oil, as grease may cause a sluggish freehub. Is this different for Shimano freehubs as I'm just about to service one and want to get the right lube for it.

[@rcj4046]

Dumonde Freehub Oil is a relatively new product specifically for this. They also have a freehub grease if that's what your freehub requires.

[@brendancreaner9425]

Whenever you can't find a suitable hex-wrench - use the head of a hex-bolt and clamp-down hard on the shaft with a vise-grip. You could even weld a lever onto the shaft of the hex-bolt if extra torque was required.
