Thanks for the helpful video. Loctite worked great on my 6-year-old RockShox Pike. But I used Loctite 648 instead of 638 since it has a much lower viscosity to help it wick into the gaps. It's also a high strength retaining compound like the 638. It's been 2 months now and still no creaking. 😁👍
The money we pay for these 36, they should have this sorted. Also The first thing to do When getting a new fox is to remove The air cartridge shaft and remove The grease wich comes stock, its so much it makes the EVOL not working. So basically 90% are riding fox 36 without getting the performance it should have,
Thank you. My Fox 34 fork is creaking. I have been looking at cables catching, looking for cracks in the frame, looking at headstock bearings. Never occurred to me the CSU was at fault. After all the test riding and stress testing Fox and RockShox do they must know what is wrong but CB A to recall a faulty product attitudes prevail to users like myself who cannot afford to buy new every few years. Come on market leaders, treat your biking customers better!
you saved my day, I replaced my fork crown under warranty but the creaking started again just after 1 month of daily riding. 10 ml of Loctite cost me 20 bucks but it was much cheaper than a brand new fork!
Have a look at clip posted by olivermajewski. He uses a hydraulic press to disassemble the csu and shows what you are talking about. I have just started trying to find a shop that will press out the stanchions and steer tube so I can repaint the crown. It should be a standard service at major bike shops given the number of people I am finding with the creaking issues. Cheers.
This trick has worked wonders for my 170mm Fox 36. Applied Loctite 638 to both stanchions but not the steerer tube. Left sitting 48 hours upside down and so far the creaking has completely disappeared!
I've had the new 38 in 160 mm travel for 4 months now and it starting having a cracking creaking sound after only 2 months of use. I'll definitely have to try this, its been driving me crazy and makes me not want to ride any rocky downhills with the noise.
Unfortunately the 38's seem to suffer from this issue a lot, it's not surprising as the extra forces going through the crown are going to accelerate the problem, EXT seem to be the only manufacturer that has looked to address it.
:D I had 3 fox forks, all were creaking (first after 3 months, second after two weeks and third started creaking first day)...On last fork I scratched legs and I sent it for creaking csu warranty so sometimes creaking is not bad :D.
Good explanation about this creaking noise, i have a fox 36 performance elite 29 / 160mm with this problem, it will be the 4th time i will send the suspension for warranty, i know that within 4/5 months i will have the same problem again.. Fox has to find a solution !!
Yeah, my SR Suntour got to squeaking annoyingly. Watched several vids and then set about adjusting the preload screw (more/less) and that cured the problem. Viola ! Too easy.
Great Video mate . I had a Fox 36 and the CSU went within a Month of getting the bike ...went off for Warranty. Went again after another 6 Months. Not Great ! I'm getting some Lyrik Ultimates ....hopefully last creak free for abit Longer !? . Great video again
@@duggan2284 Tried loctite on an older Pike (2018) that also has the same problem, did not work, so not putting that stuff on the new Lyrik. Either I'll somehow live with the massive cracking voice or warranty it at some point. But does the warranty even do any good, as as soon as I get a new fork/CSU, it will just start creaking again..? :(
Tomi Saaranen Yes it’s super annoying, especially on a new fork. My last fox 36 had the same issue after just a couple of months, decided to give the Lyriks a go this time in an attempt to a escape the dreaded creek! But it seems to have followed me 😂 I’ll wait for the weather to turn at the end of summer and send them back. Think it’s just luck of the draw if you get a defective set, seems to be an issue for most manufacturers.
Do they replace CSU under warranty, if there is that sound? I got a new bike, and the first thing I heard after hopping on it is that creek sound... Or should I just put loctite and forget about it?
Man! Very informative and this seems to be the exact issue I'm having with my 2019 Scott Spark 910's FOX 34 Performance Elite fork. Will give this a bash!
My brand new Santa Cruz 29” with Fox 36 is doing it after a week. Took it on a pump track 3 times didn’t even break it in on any rough stuff yet. Kind of frustrating
My 2019 Tallboy has a creak/snapping sound when I shift weight or depress the fork. Any luck getting it sorted out? I’ll take mine in soon.....frustrating....
There is something called freezing spray (translation to english). Dont you think, it can be used on the crown to increase that locktight ability find its way in between legs and the crown?
Hey does anyone know if this creaking is going to break my fork eventually or this just means that you will have a noise I don’t know how to take apart my fork but If all it does is take away sound if I send it in. I don’t want to spend the extra money
Thanks for a great tutorial dude 🤙. Now going to try it on my 2019 36. I always thought it was the headset, replaced the headset and it’s the same... the sound is exactly like that snap sounds on yours🤞I get good results 😬
Man i Wish i saw this Video sooner have this Problem for more Then a year now ,But i was Out of warranty and fixing IT was to bothersome. Didnt try but the First Thing in the mornig i will get the loctite. Thanks very much if IT works
I ve been oiling the fork constantly thinking it would fix the problem but didn’t. Fork actually works great but the noise was doing mu head in. Just ordered this one this thing. A bit pricey but i hope it works
I have tried this to no affect, following the exact steps maybe it might just be my fork, I’m hearing the exact same clicking sound as I am before, any tips?
Thanks for this info. My CSU is creaking on my fox 38 not on compression but steering. Even without pressure if I lift the front wheel off the ground and turn the bars left/right it creaks. Any ideas??
Worth checking the headset and bearings, if it's not that and it's still under warranty contact FOX via whoever you got the fork from and they should replace the CSU. If it's out of warranty www.rsfsus.co.uk offer an excellent service to resolve the issue.
It will be temporary as it's a design fault by the manufacturers, it would cost them more to fix than just doing warranty replacements, If you want a stronger fix www.rsfsus.co.uk offer a great de-creaking service.
@@jedmtb I saw you clean that area but was not sure if you used loctite there...I replaced a headset thinking the issue may be the crown and lower bearing contact. Maybe loctite would have solved the issue. Sold the bike so cannot experiment now
Hi, I have my Rock SHox Yari solo air with 160mm travel on Giant Reign 2018, the bike is new and this snapping and creaking sound developed only after 5 short rides in dry conditions. Do you think that the fork has the same problem?
Will this void my warranty? Just bought a Fox 38 and it's scary how much it is creaking. I want to solve this but I don't want to lose my fork 2-3 weeks for warranty claim mid season
It didn't with mine but if the fork is new I'd contact FOX and they will replace the CSU, it's a lottery as some are quiet and others creak like crazy.

The chance of success should be greater with loctite 290 as it is much much thinner and will more easily find its way down there. 638 isn't really considered wicking grade, even if it probably works this way to some extent.
I've applied the 290 - it works fine - I'd say 95% of the creaking is gone. However, it is made for threaded metal parts, whereas the 638 is a press- fit application.
@@jedmtb wow rough. I was just wondering coz you've got American parts and American heavy brands. Lol. Is it good there it looks like the peak district
This is absolutely horrible. We pay 1000+ for these forks and I’m yet to find one which does not creak after few months of usage 🤬 I tend to keep my bike free of any noise but no matter I do I can’t get rid of CSU creaking. Frustrating. Brake - Click - brake - click… 😢
I've not tested them but from the specs they might work, if you try them please consider posting another comment, I'd be interested to hear how they work.
Finn I’ll give you a bit of an update because I’m sure your super frustrated searching the internet for a solution to the creak, just like I was. I gave my forks to my local bike shop, they sent it in to fox and I got given a full csu replacement for no cost. I was creak free for a few months and then all of a sudden my archenemy (the dreaded creak) came back after a muddy enduro race day. I was super pissed as the first time I got the csu replaced I had to spend 2 weeks away from my beloved bike 😢 I honestly couldn’t be bothered to take the forks back again so I pulled my headset out, pulled my crown race thingo off and put some fresh grease on everything and just let it be. I haven’t heard a creak since and it’s been a good 5 months. So my advice is to just let it be, it might be annoying for the mean time but I suppose after a while things wear in. However, if you have any scratches on your stanchions now you know you can get some fresh new fork uppers for no cost, just say you have a creaky csu 😏 I hope this helps you out a bit 🤞🏻
Question. If the creak is coming from the crown/steerer interface, would it still make a noise during that test? I tried it and got a few creaks initially but it stopped after that. Also did you have to remove your crown race to clean and apply the loctite to steerer tube? Sorry for all the questions.
@@jedmtb I see. One more question. What was the reason behind using 638 and not 648? I just ordered some 648 because I couldn't get 638, and 648 is apparently less viscous and able to get into smaller gaps. Haven't got it yet but I would think it would work better for this application
@@shrimpfriedrice494 I was recommended 638 by a Fox service center, the 648 does look like it should work better tho, please let me know how you get on with it.
@@perttukoo The creaking turned out to be coming from the headset cups. I would still recommend the 648 as it's properties seem more suited to this application. Less viscous so it would have a better chance of getting into any gaps.
So my question which I cant seem to find a solid answer to, is that is this just something thats annoying, or is it a legitimate mechanical concern? Because if its just an annoyance I don't feel like wasting my time an effort with a warranty process, my car makes tons of weird and annoying noises but its totally normal and just a part of it aging. But if its a serious mechanical concern then I would for sure be talking to fox while these things are still under warranty.
Its just annoying. If your fork is still in warranty you can send your Fork to Fox for free but the people who come here probably dont got any warrenty on their fork left..
Very interesting! But my Fox 36 170mm have more of a clicking sound like that th-cam.com/video/7dBo7NSag24/w-d-xo.html And yet when i talked to a Fox-trained mechanic his first guess was that its the "crown" fault that need to be replaced. i think he ment the entire CSU, that is the same problem adressed here.
@@danielzahradnik2571 yes, it turned out i didnt tighten some things enough. It looks like fox mechanic overtigten it then a little bit and all the sounds disappeared
Telling people to twist there forks around like that is not a smart idea. There’s always that one guy that goes overboard and brakes the bridge in the lower.
As if the forks don't already take that kind of force x100 while riding. If a fork breaks from twisting it with your hands then it's probably a good thing you won't be riding on it anymore.
@@djmystery7235 He's not really twisting it in the video. He's moving one side back and one side forward, similar to how the fork will flex when encountering square edged hits on a trail.

Thanks I appreciate it!
Did you try to fix the creak with Loctite? Did it work?
@Patrik Rumin, phill is to busy to answer that...
phils videos reflect this
Heating up the crown with a hairdryer or heat gun will also help open up any gaps. It’ll help the Loctite to wick in, as it’ll thin out more.
Thanks for the helpful video. Loctite worked great on my 6-year-old RockShox Pike. But I used Loctite 648 instead of 638 since it has a much lower viscosity to help it wick into the gaps. It's also a high strength retaining compound like the 638. It's been 2 months now and still no creaking. 😁👍

@@jedmtb wow rough. I was just wondering coz you've got American parts and American heavy brands. Lol. Is it good there it looks like the peak district
Got an eBike with some 36 factory’s, it’s happened after 3 months 😢 warranty time...
I tried this and it didn’t do anything - apparently the CSU can also cause the creaks and needs to be disassembled and cleaned. Clear my calendar!
Yes the CSU is the issue, you can get it replaced if the fork is still under warranty or www.rsfsus.co.uk offer an excellent service.
Rode my new Polygon T8 with Fox 32s
less than a week an creaking started
Is it ok to leave your bike up side down for a night?
Yes it actually helps lubricate the foam rings under the seals.
Honest question: is this actually a problem (apart from the creaking noise)?
In most cases no, it's just annoying.
@@jedmtb Good to know! I think I'll leave it as is.
This is absolutely horrible. We pay 1000+ for these forks and I’m yet to
find one which does not creak after few months of usage 🤬 I tend to keep my bike free of any noise but no matter I do I can’t get rid of CSU creaking. Frustrating. Brake - Click - brake - click… 😢
What about loctite 641 or 680?
I've not tested them but from the specs they might work, if you try them please consider posting another comment, I'd be interested to hear how they work.
Did they work out? I can't find 638 anywhere!
Is it safe to ride the bike even if it creaks?
Yes, I think of it like a creaky door, it works fine it’s just annoying.
@@jedmtb thx, I'm already trying your method but on the steerer tube because I think the creak is coming from there
I have had my 2020 fox 36 grip 2 factory for 7 days and I am starting to notice a creak 😡
That sucks! Not had it happen that quickly before hopefully you can get them sorted.
Also got my 36 brand new and after 2 DAYS it started creaking
Finn I’ll give you a bit of an update because I’m sure your super frustrated searching the internet for a solution to the creak, just like I was. I gave my forks to my local bike shop, they sent it in to fox and I got given a full csu replacement for no cost. I was creak free for a few months and then all of a sudden my archenemy (the dreaded creak) came back after a muddy enduro race day. I was super pissed as the first time I got the csu replaced I had to spend 2 weeks away from my beloved bike 😢 I honestly couldn’t be bothered to take the forks back again so I pulled my headset out, pulled my crown race thingo off and put some fresh grease on everything and just let it be. I haven’t heard a creak since and it’s been a good 5 months. So my advice is to just let it be, it might be annoying for the mean time but I suppose after a while things wear in. However, if you have any scratches on your stanchions now you know you can get some fresh new fork uppers for no cost, just say you have a creaky csu 😏 I hope this helps you out a bit 🤞🏻
Thanks for tips, will the loctite flow to the headset when left upside down overnight?
Tried this and it did reduce creaking but did not stop it
Yes unfortunately it's not 100% hopefully the manufacturers will address it as the bigger forks ZEB/38 will make the issue worse.
Question. If the creak is coming from the crown/steerer interface, would it still make a noise during that test? I tried it and got a few creaks initially but it stopped after that. Also did you have to remove your crown race to clean and apply the loctite to steerer tube? Sorry for all the questions.
It depends on the fork, some have more movement than others, you can remove the crown race but with the forks I've done I haven't had to.
@@jedmtb I see. One more question. What was the reason behind using 638 and not 648? I just ordered some 648 because I couldn't get 638, and 648 is apparently less viscous and able to get into smaller gaps. Haven't got it yet but I would think it would work better for this application
@@shrimpfriedrice494 I was recommended 638 by a Fox service center, the 648 does look like it should work better tho, please let me know how you get on with it.
@rowan. Did you try the 648 and did it do the trick...? Curious because I need to buy either 638 or 648.
@@perttukoo The creaking turned out to be coming from the headset cups. I would still recommend the 648 as it's properties seem more suited to this application. Less viscous so it would have a better chance of getting into any gaps.
what would be better loctite 290 or loctite 638
I've only tested 638 at the moment but I have some 290 on order to test it.
@@jedmtb 1 month passed, does the 290 worked ??
@@florianpaste6594 I've tested the 290 and it seems to work, I can't say yet if it's any better yet tho
@@jedmtb what about loctite 680 its a lower viscous loctite i believe
@@VikMTB It might work, if you try it please consider letting me know if it works :)
Sadly didn't work for me :/
@@trotro80 :(
So my question which I cant seem to find a solid answer to, is that is this just something thats annoying, or is it a legitimate mechanical concern? Because if its just an annoyance I don't feel like wasting my time an effort with a warranty process, my car makes tons of weird and annoying noises but its totally normal and just a part of it aging. But if its a serious mechanical concern then I would for sure be talking to fox while these things are still under warranty.
Its just annoying. If your fork is still in warranty you can send your Fork to Fox for free but the people who come here probably dont got any warrenty on their fork left..
Very interesting! But my Fox 36 170mm have more of a clicking sound like that th-cam.com/video/7dBo7NSag24/w-d-xo.html And yet when i talked to a Fox-trained mechanic his first guess was that its the "crown" fault that need to be replaced. i think he ment the entire CSU, that is the same problem adressed here.
no, this sound you have is in your fork, no crown
@@danielzahradnik2571 yes, it turned out i didnt tighten some things enough. It looks like fox mechanic overtigten it then a little bit and all the sounds disappeared
Telling people to twist there forks around like that is not a smart idea. There’s always that one guy that goes overboard and brakes the bridge in the lower.
As if the forks don't already take that kind of force x100 while riding. If a fork breaks from twisting it with your hands then it's probably a good thing you won't be riding on it anymore.
Rowan when the wheel is on it doesn’t get twisted around as much, if you remove the wheel it’s really easy to break it.
@@djmystery7235 He's not really twisting it in the video. He's moving one side back and one side forward, similar to how the fork will flex when encountering square edged hits on a trail.
