- Fresh fork seals can take your MTB suspension from feeling draggy and sticky to feeling plush and smooth! Replacing the dust and wiper seals is something that you should be looking to do on your bike every now and then, either when you feel like they need a change or according to the manufacturer's stated service periods. It doesn't take long to do, Anna is here to show you how.

The unior seal driver is great to drive the new seals. They make them in different sizes for different seals and it's more or less idiotproof
Keep up the good work Anna 🥰
Thanks Anna, great job!
Thanks, Tim! Glad you found this one useful!
I didn't realize you were a lefty. Good video.
I happen to have a few dentist's picks (I'm not a dentist!) and those are incredible for extracting seals on forks and shocks - even good at getting circlips removed too sometimes.
Nice 🙌. Thanks
Glad you enjoyed, Jon! 👊
That ring spanner tip saved me!
Plastic tire levers are good for popping out seals
Would be helpful to show how to put the fork bak together
I was watching Calvin of Park Tools do this job once, he used a tire lever to pop the seals out.
That's also a great thing to use! Anything smooth and rounded can be used to prize the seals out. 👍
So only a 5 min job of your forks are already in bits and you have no plans to put them back together again.
Ok but getting a fork off the bike and apart maybe takes another 5-10min. You can still do this in under 30min and what they've shown is the more technical part that would discourage people from doing it themselves.
Literally said at the start about the lower leg service - so a five minute job where you are doing that.
Nice 👍
Thank you! 👍
#AskGMBNTech Question I always seem to run up against is lubing the ceramic bushings of derailleur jockey wheels. I typically avoid doing so - only service I provide there is taking apart and cleaning up the ceramic bushing once every blue moon. Other people lube those bushings, but that's an unsealed system and a potential dirt magnet. What's the real way forward here?
Hi, I have Fox suspension on my Nukeproof Mega 2021, and I've recently noticed my rear shock Float X2 doesn't really lock out, it seems just a bit stiffer than "open" setting. Would you be able to point me out in the right direction to fix it please? Thank you!
Are these SKF for seals, right?
I have a rockshox fork and the seal comes up on one side like the little ring doesn't which is usee for measuring sag what should I do?
I always use suspension grease on the dust seals, Anna you didn’t is it not necessary to use suspension grease?
#AskGMBNTech Hi Anna, thanks for the video on replacing Fox fork seals but what are the signs and symptoms of needing to replace the seals vs. just needing to clean/replace the foam rings?
There are none, do seals and foams every other lower leg service
Hi Mark, Anna here! When you compare an old seal and foam ring to a new seal and foam ring, it's easier to tell. Generally, you don't want any cuts or holes in the rubber part of the seal (as this will let mud and water in), and the metal ring should look uniform all the way around (not damaged or hanging off, which i've seen!). The foam rings may get dirty or change colour, but if you clean it and it's not damaged or significantly smaller, baggier or deformed than a new one, it can probably go back in. Best of luck :)
Do you reuse the compression washers? Or do you buy a complete rebuild kit and only use the dust seal, foam ring, and compression ring? Or do you skip the compression washer?
I’d just put new on, you can buy a few at a time to have as spares
@@woduk can you buy them as an individual sku? I have only seen them in full rebuild kits
aside from being damaged, how will you know that you need to replace them? thankss
The stock ones are nowhere near as good as the green ones so probably when you get the forks
If my stanchion is 30mm what size dust wiper kit do i need, 30mm or 32mm?
30mm
Hey, is there any way to install the seals without that stupidly expensive seal driver?
Remove the springs of the seals and use a socket that sits on the flange and tap with a mallet.
How do you tell whether your foam rings are bad or not? Is it coulor of tear
Dirty, they soak up any dirt that gets past the wiper seals. They can be turned inside out but better to replace. Wipers don’t always need replacing though as they wear in.

The lee-vering seems to be the trickiest part of the job...🤔
Love the bike design ua-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L and functionality. It is hard to align the front tired to center the disk brakes. The brake wheel touches the stationery side of the brake caliper and pad. I aired the tire up to 40 psi as the markings say 40-60psi. Left the house for a few hours and came back to an exploded innertube.All in all it seems to be a good bike. Have not ridden it yet though so that's the max of my knowledge. Update, put a new innertube made sure the tire was set properly and it did the same thing in under 20 minutes as second pic shows.
If you replace the seals you also replace the foams...
Just soak Them in new oil thats it
Nonsense!

You were very lucky not to break the top arch of the lower legs in this video; holding them on one side and applying force to the other side both when removing the old seals and hammering in the new ones is what not to do. Any time you remove the lower legs, refit the axle on a thru-axle fork to reduce the possibility of the top arch flexing and breaking. On forks with QR dropouts, use the plastic insert that came with your fork when new in the box; your LBS will probably give you one FOC if you don't have this.
I never thought of that! reinstalling the axle seems a good practice
Do you realise how much stress these forks are under when you are riding hard. The minimal force needed to press a seal in is nothing.
@@Adam-vm8kp It is a different force being applied. The top arch of the lower legs is really not engineered to withstand forces pulling the legs apart or pushing them together. During normal operation the CSU as well as the front hub and axle limit that movement. They're not as delicate as some believe, but many lower legs have been broken in this manner. Just hold onto the fork leg you're working on when removing/installing the seal.
@@ziplockk I'd love to see that!
She used a soft hammer, plastic knocking in rubber seals is fine, the aluminum structure is far more
Resilient, if it were steel inserts & direct hit from a steel hammer then maybe after a few heavy blows creaping could become an issue, also she was holding the fork with her hand, suspending in mid air, that is added recoil & dampening, haters and critics get your facts sorted first.
OMG is that a tutorial how to waste a fox 38 factory ?
that lower leg was hammered one side being held by the other side with no axle in...
also, you need way more than a few drops on the foam rings, in fact I'm sure professionnals use vaccum to make them fully saturated with oil.
She put way too little oil on the foam rings and all of it on the outside too. That thing is going to lubricate the stanchions with mud at best. Their fork service videos are consistently horrible. Fox has detailed service instructions with photos which is way better reference for anyone trying to do this.
It's nice to see naively believing every manufacturers revenue collecting tactics
2023… and here we go again 🤦🏻♂️
What a disappointment of a video! I was expecting a start to finish video. No information about how much new fluid to install or how to install it. Nothing about inspecting the drained fluid for any debris. I would definitely skip any other videos she my have on UA-cam.
Fluid volume is fork specific. Consult your manual
