DIALED S2-EP9: How to Service Lower Legs on FOX Forks | FOX

[@01FozzyS]

Well done,Jules! Fox should do a feature on the mechanics i.e. their background, what trails they ride, bike checks, etc.etc.

[@jordicortes4993]

01FozzyS that’s not a bad idea!

[@andre.monteiro]

Anyone else looking at this because their shiny new 1000€ Fox 38 needs a service to remove the ton of grease in the negative chamber they put at the factory making for a poor performance fork?

[@Nikica358]

Grease to keep the washer on the nut is ultimate trick!

[@sassanpazirandeh4808]

Great video jules. Thanks . Easy to follow. I noticed you didn't change the seals. Just the foams. I assume if one does not see any obvious damage to the seals it is ok to just change the foam and the oil on the routine service?

[@laurentsquartero9218]

Thanks for the well-done video Jules! Q: What is recommended for the foam wipe rings on damper side? Is the PTFE teflon infused 5wt recommended, or the 20wt gold just like on the air side? If 20wt gold is recommended, wouldn't that contaminate the lowers that contains the PTFE teflon infused 5wt?

[@patrickguerreiro9760]

I'm wondering the same thing. I'm about to service my 34s with the GRIP damper, which calls for 5 wt PTFE infused oil for the damper lower. However, I'm unsure of what oil to soak the damper side foam ring in: 20wt gold or 5wt ptfe? Any clarification would be appreciated! Thanks for the great videos!

[@seanec8]

Why wouldn't it be the 5wt lol!

[@jordicortes4993]

It’s whatever is used in that leg. So grip would be 5wt , the other dampers would be gold

[@andrewgreenhouse8116]

Great Series! Are the foam rings available separate and if so how do I order them? Every #ridefox video I have seen the seals are not replaced. Is this considered a race service or should the seals always be replaced?

[@wabidabidoo]

Foam rings are available in most online shops. From what i've heard the wiper seals only need to be replaced if they're worn or scratched.

can we do a damper service as well? that would be helpful to do a complete tune up during this period!

[@tajhendry9798]

Bernard Goh Good idea!

[@hunterwright386]

I can’t find a single video on how to service a damper...

[@jordicortes4993]

Bernard Goh one thing to remember is grip1/2 are somewhat recirculating dampers and they don’t invest damper fluid. So service is far less critical. If you’re looking for old damper info just go to ride fox.com

[@seitenryu6844]

Grip is dead easy to service. Buy the shaft clamps and you're pretty much set. Take off the top, dump out old, flush a bit, then fill again. They say it doesn't ingest oil... that's only a half truth. The seal can scrape off R3 pretty well, but can't manage with Fox Gold or other bath oils. Hence why they don't use Gold both sides.

[@austinlavallee1495]

Where can I find quality syringes like in this video? I cant find good ones anywhere!! All I can find online is crappy cheap ones that are one-time use. I'd like to find good ones that will last a long time.

[@deanallendj]

Austin Lavallee was literally just about to ask this question... needs a answer asap

[@deanallendj]

Austin Lavallee on second thoughts to this, I recently done a full fork service on a set of 2014 rockshox recons. I ordered a small syringe for the lowers bath oil “6ml each” but I needed about 130m for the damper. I found a unused stans no stubes syringe (60ml) and made sure it was extra clean. Worked a treat, thick material & seals. Didn’t give it much thought till now

[@tajhendry9798]

Austin Lavallee get some Veterinary livestock syringes they are the best and what we use. 💉

[@guy3k256]

I assume you don't have to let the air out the forks before you start? cheers.

[@JoeyG333]

Come on mate common sense like

[@m1chaelsc]

As long as your not pulling the air spring out you don’t technically have too but if there’s air on the air spring it make putting the lowers back on more challenging.

[@tajhendry9798]

No need to remove the air unless your pulling the air shaft or removing the top cap. With experience it becomes easy to pop the lower on the the shaft in place. 🤘

[@BenNemec]

If you do let the air out, make sure you put enough back in to fully extend the air spring before you put the lowers back on. Otherwise the lowers will end up with a vacuum and turn into a giant negative spring (not as cool as it sounds, trust me).

[@mtbjim1670]

Thanks for the vid on this. great thing to do while were all tied up at home...

[@mtba102]

Will doing your own lower service void ones warranty?

[@justinrickard5972]

Whats up Jules. So awesome to watch you do this. Very well explained. I wanted to ask where did you get the syringes for the oils. I have been looking for ones like what you used and have had a hard time finding them

Slick Honey or Slickoleum

[@tolgaakyay]

Fox recommends this every 30 hours. I’m not good at noting my hours 😊 Shall we say every 3 months overall? I don’t push it very hard and I don’t ride in the wet too much.

[@ameurstihn6610]

Depends on how much you ride.. If you ride like once a month cause you've got one busy ass job.. (I'm totally making fun of someone I know).. You only need to do it every 5000 years..

[@EpicEvolution]

30 hours with average 20 km/h is 600km. If you don't ride in wet dirt and dusty conditions, you can increase service interval to 1000km. And then look at fork condition to increase or decrease next interval

no onlny when there is a leak at the bolts...

[@tajhendry9798]

Kristjan Valenčič we would recommend it.

[@Windband1]

Yes because they are crushed once you put them on! That's why they're called crush washers. You want to use fresh ones when you reassemble each time! Cheers.

[@seitenryu6844]

Is anyone going to bring up the crappy R3 teflon fluid? What is a solid lubricant doing in a fork fluid? If it settles in the bottle, it's not mixing very well in the fork. First thing I do is ditch that for Motorex or Plush fluid. Both feel great.

[@zacharytyser]

if im servicing the air shaft should i add the small amount of oil recommended to the air chamber after i have changed the oil the lowers then charge the system or should i add the oil to the air chamber then charge the system and then add oil to the lowers to finish? I have seen it done both ways w/o explanation for the choice

[@deanwest78]

pop the air cap off and add 3cc oil. (without air in it)

Cant you do a tours of the bike shop

yes, but you may as well check the air spring as well in this service as it's very easy

[@jsrocker248]

Tad late to answer but yes, the oil is still gonna be the same since all your changing is the travel and any air shaft you add in bottom out at the same point as the rest. Also these volumes are for the lowers so still, same oil volume.

[@boobiemcdonalds7835]

Shouldn't the very first step be to release the air pressure from the forks?

[@tylerbrenn]

You don't need to, there is no pressurized air inside the lower leg

[@willinsley2457]

cool

[@78James]

Is there a technical reason why you can't use the teflon oil in both sides?

[@wtfeatapples]

Teflon Infused is 5wt and FOX Gold is 20wt.

[@krzysiu4003]

The 20wt gold is just for lubricating the bushings so I don't see no reason why a lighter oil couldn't be used. Would have thought a heavier oil is more likely to stay around the bushings and do a better job though.

[@jordicortes4993]

It’s not as well suited as a lubricant. So technically you couldn’t. It’s just not smart

[@krzysiu4003]

Oops, but probably smarter than putting 20wt gold in the damper ;)?

[@seitenryu6844]

There is not. You could do it just fine. Would be a mistake though, since it's a poor bath lubricant.

[@wtfeatapples]

Whats the name of the grease? Would SLICKOLEUM SUSPENSION GREASE work? Thanks for the video.

[@tajhendry9798]

NOBLE WULF Slickoleum grease would work just fine.

abr sam If the seal was leaking or was damaged it would need to be replaced. We would do this service at a race or in between full services, in a full service you would replace the seals.

[@elwoode8664]

What went wrong if the lowers won't slip on this easy on the stanchions ?

[@542eastWA]

enduroforkseals.com sells the foam rings individually

[@TPV07]

542eastWA good shout out. Andres make sure to measure the foam ring height. Different forks have different foam ring heights. I fitted a push seal kit which is awesome on a 2year old pike a few weeks ago and the ring in the kit is only 5mm it needs a 10mm ring. It will probably work but not filling the gap totally is not ideal and you can push the foam ring easily in the lowers that way too. So measure it and be careful when installing it.

[@krushiXX]

Yep FOX does not sell the rings separately, I was asking my local FOX service center about those. I'd better replace them rather to wash in isopropyl as they swell up a bit. They seem to return to the original shape after drying out, though.

[@michaelb9664]

Why is it so difficult to find out what size foam rings fit which model forks? It seems you’ve got to disassemble the lowers to find out what size the foam rings are. It would be better to have the new ones ready in advance before having to take the lowers off. Lower leg services are very easy, but finding the correct parts and oil requirements for the fork beforehand is a time consuming effort. It would be nice to have oil weights and capacities printed on the same sticker as the suggested air spring pressures for rider weight. Along with the size of foam rings for that specific model. Especially considering how ridiculously regularly we’re recommended to service them. I guess it’s made harder to encourage people to pay for the extortionate fork servicing costs, instead of having to go to the hassle of doing all of the research first.

[@jordicortes4993]

This doesn’t make sense to me sorry. If you have a 34 you use 34 foams and so on. We have a complete breakdown on our website as well. Did you actually look?

[@michaelb9664]

jordi cortes nowhere on the Fox website can I see foam rings available on their own. There are seal kits, but it’s not necessary to replace all of the seals as part of a lower leg service. I can’t find any breakdown of parts that shows which foam rings are for which fork. Do you work for Fox?

[@seitenryu6844]

For oil heights go to biketechtools.com Love that site.

[@gebhardt2]

Why is she putting in the specified amount of oil Fox recommends? Of the 10 Fox forks I've ever opened, none have had a total of more than 5ml of oil come out. An oil pan is complete unnecessary. I'm expecting 30ml+ to come out but never more than 5ml comes out. The foam is always near-bone-dry and the wipers have no grease of anykind. Why is that? For you DIY guys at home, you know what I mean. I'm talking about brand-new forks or forks rebuilt by Fox. Also, you'll never find a 5ml pillow-pack in a shock can either.

[@JMVC]

LBS mentioned that forks never seem to come from factory with the right amount of fluid (which seems off), but you seem to prove them correct. Maybe I won't wait to service my new suspension.

Not funny I didn't laugh. Your joke is so bad I would have preferred the joke went over my head and you gave up re-telling me the joke. To be honest this is a horrid attempt at trying to get a laugh out of me. Not a chuckle, not a hehe, not even a subtle burst of air out of my esophagus. Science says before you laugh your brain preps your face muscles but I didn't even feel the slightest twitch. 0/10 this joke is so bad I cannot believe anyone legally allowed you to be creative at all. The amount of brain power you must have put into that joke has the potential to power every house on Earth. Get a personality and learn how to make jokes, read a book. I'm not saying this to be funny I genuinely mean it on how this is just bottom barrel embarrassment at comedy. You've single handedly killed humor and every comedic act on the planet. I'm so disappointed that society has failed as a whole in being able to teach you how to be funny. Honestly if I put in all my power and time to try and make your joke funny it would require Einstein himself to build a device to strap me into so I can be connected to the energy of a billion stars to do it, and even then all that joke would get from people is a subtle scuff. You're lucky I still have the slightest of empathy for you after telling that joke otherwise I would have committed every war crime in the book just to prevent you from attempting any humor ever again. We should put that joke in text books so future generations can be wary of becoming such an absolute comedic failure. Im disappointed, hurt, and outright offended that my precious time has been wasted in my brain understanding that joke. In the time that took I was planning on helping kids who have been orphaned, but because of that you've waisted my time explaining the obscene integrity of your terrible attempt at comedy. Now those kids are suffering without meals and there's nobody to blame but you. I hope you're happy with what you have done and I truly hope you can move on and learn from this piss poor attempt
