How To Perform A Lower Leg Service | Mountain Bike Suspension Fork Service

Over time, dirt and grime can make their way past the seals and into your fork's lower legs.This increases the stiction and can reduce the longevity of your suspension if left unattended. Here's how to perform a lower leg service to keep your fork clean and well lubricated 🔧

Another trick I use for the foam rings is, use a small clear bag (usually the packaging it came in) and put some 20wt into it with the foam rings and just move the oil and rings around in there to soak the foam effectively. It does not use much oil that way in comparison to filling a dish with oil.

[@redtobertshateshandles]

Your kids will probably throw those oil bottles out still 80% full.

[@mushieslushie]

I just put some oil in a red solo cup and drop then in. I'll then use my syringes to also suck oil out of the cup rather than try and do it from the oil bottle. When I'm done whatever extra is left in the cup I just pour back into the oil bottle.

Fun fact for everyone. It is best to not use your torque wrench to place the nut/bolt down. Only use the torque wrench to torque it down. He does so in the video like you should. I have a buddy who uses his torque wrench for everything and it drives me crazy. I have worked with people who calibrate these for a living and it damages the torque wrench over time.

[@jamietennant2688]

Another great video Doddy. Would love to see a video on how to carry out a basic air can service too. Keep up the good work🤘🏽

[@marcopintosouza]

Nice job Doddy. Souza from Brazil. I made a career in the field of industrial maintenance, going from apprentice mechanic to mechanical engineer in the 30 years of profession. During this period, I had the opportunity to perform maintenance on hydraulic components such as servo motors, hydraulic cylinders, pumps, etc. As I already work in this area, I also maintain my bike, including the suspension. Regarding the maintenance hour interval for the suspensions (125 FOX and 150 Rockshox), I always question whether it is really necessary to have such a short time interval. At first, I strictly followed this interval time, but I increased this interval as I verified that the oil and seals were intact. Today I do lower leg every 300 hours, and complete maintenance once a year. Even increasing the interval to one year, the oil in the hydraulic chamber is intact. As I mentioned, I've worked with hydraulic cylinders with services much more severe than a bike suspension. I wonder if I had to do maintenance at intervals as short as bike maintenance. I know that with regard to the lower leg, you have to be very careful if you make a decision to space it out. However, opening a Raceday cartridge every 150 hours, or a FIT4 Fox every 125 hours, doesn't seem very correct and/or necessary to me. In your experience, what do you think about these time intervals, especially the maintenance of cartridges?

[@juffkasvennsson4609]

What an incredible yet unnoticed comment

[@syammimarifin3437]

Apply the same mtb standards to automotive damper/shocks and it would be totally unacceptable

[@rustler08]

The intervals of these components, especially something like the Fox Factory/Performance Elite or the Lyrik/Zeb Ultimate, are because they are race components. They are definitely on the strict side and can likely be stretched out some.

[@rustler08]

​@@syammimarifin3437 Completely fallacious comparison. The shocks on standard cars are essentially equivalent to what you find on a Walmart bike. They are completely unserviceable and are designed for generic use. You are comparing literal race-grade components to generic sealed units.

You've already made multiple videos on lower leg service (along with everyone else) how's about some videos on full damper services. You've still never made one of those and I'm sure there are lots of people that would like to see this for both rockshox and fox.

[@BGraves]

Manufacturer has these videos too... Zzzzz

[@zoubtube]

@@BGraves I've never seen damper service videos on both Rockshox and Fox websites. I've only seen lower 50 hour service and upgrading damper videos. They do have how to PDF's to service dampers, which I've used for years, but they are very general and typically always seem to be missing steps. if you come across full damper service videos from front and rear from either company feel free to share. thanks

[@abtcup]

Damper services can be beyond the abilities of a lot of home mechanics. Its something where you can easily make a mistake and not notice until its too late. There is a good reason why you don't see too many damper DIYs...its because its a lot more difficult to do than a seal and oil change. Heck...they don't even show you how to remove the fork seals in this video. There are also many small parts that can easily be lost. If you want a damper that's relatively easy to service...get a DVO or Manitou...skip Fox and Rockshox.

[@BGraves]

@@zoubtube once you are into the fork and you pull out the damper it is all pretty self-explanatory especially with the help of the PDF. Perhaps that's why videos don't exist. It's not rocket science once you're in. Same for rear damper

I did a full service on my Manitou Markhor over the winter and the difference was incredible. I know Daddy mentioned the Step Cast tools being a barrier to entry, but assuming you need to do this at least once per year they will pretty quickly pay for themselves, same with the special Fox sockets if you're looking to service the uppers.

[@davidbea3711]

EVERY 3-6 MONTHS, DEPENDING ON USAGE

[@alexguiver815]

Excellent vid Doddy, thanks! A couple of things I'd like to add though; if you don't have a seal driver you can install new dust seals perfectly using a long length of threaded rod right through the lower leg with nuts and washers on the bottom (and possibly a couple of layers of old inner tube to avoid scratching the paint) and an appropriately-sized socket on top of the dust seal. Set up carefully this guarantees the seal will enter and seat into the lower leg squarely as you press them in by doing up the nuts on each end. If your fork is brand new this is also a great method for installing the star fangled nut after cutting the steerer tube to length (a lot of bike shops just beat them in). Also if your fork has QR dropouts, go to your LBS and get hold of one of those plastic inserts which are in the dropouts on brand new bikes and fit it as soon as you remove the front wheel; this protects the dropouts from scratches/damage and ensures there's no chance of snapping the lower legs across the central arch (ordinarily the lowers get a lot of their structural integrity from being assembled to the crown steerer and when you remove them they're quite susceptible to this). Hope this helps someone!

[@frankthetankricard]

Good one. PVC pipe and a mallet works just as well.

[@lozetchells9164]

Or a big socket of the right diameter, that's basically all the custom tool is

[@ScbyPwr]

Should have gone into the air chamber to fix the flaws from the factory. Specifically, the gloop of grease in the negative air chamber that Fox has never fixed and is in every fork. Thanks

[@alexmalone1642]

Hello 👋 from Bucharest România 🇧🇪 👍

Just soak the foam rings, dont f around with a syringe, you might waste an ml of oil, but its the way its supposed to be done for full saturation.

The seals can be installed using a socket that fits over the seals. Not as good as the special installation tool which guides the seals straight as well, but it can be done.

That Slick Kick is brilliant grease, I’ve got a huge tub of it for my three mtbs, you save money getting the 500g tub rather than those little tubes which cost £20, you can get the tub which is £40 but has ten times the amount in it !!! It’s a no brainer !!!

Nice tutorial Dodd. We all should know, but you've missed the safety googles 🤔 cheers.

[@andrewford80]

At the risk of sounding like a safety nerd: I would strongly recommend wearing eye protection when using any kind of canned solvents like brake cleaner. I made this mistake once and got a can with a faulty nozzel and ended up with brake cleaner in my eyes. Not only did it hurt but for a while I was convinced I was going to go blind. Really easy to just pop some safety glasses on. You never know if there is a leaky nozzel on these things. As you were.

You've done about 5 videos on servicing air forks but not 1 for coil forks. About time maybe?

the only difference will be that you will have a coil instead of an air chamber. As this maintenance is about wiper seals and it's lubrication the principles are the same for both kind of forks

Some coil forks like the one I have aren't worth servicing the cost alone is a big factor it's sometimes is cheaper to replace the fork instead

Should you smear some silkoleum / SRAM butter on the upper bushings of the lowers before re-assembly? I think the grease would stay in place better than suspension oil alone for less wear of the stanctions.

Hello planning to use this video to do my first lower leg service on my fox 36 performance forks Only question I had was you said the job may require some special tooling but did not see any use of it during the job. Is using the 10mm and 15mm to tap the legs free enough ?

[@Adam-vm8kp]

You don’t need to use the fox lower leg tools, they are very good and take all the risk out of hitting the lowers or the adjuster in the damper side though.

[@svdk1506]

Heyyyyyy you gotta hold the handle on the torque wrench to get the right torque. Good video though 😁

Doddy, is there need for this fork to add 3cc of oil in air chamber (where tokens are), no one mentions it on videos, but there is somewhere in documentation?

[@Adam-vm8kp]

Fox recommends 3cc of 20wt gold above the air spring.

[@khristopher5161]

I recently serviced my Fox 36 and I am seeing small amounts of oil on my stanchions ever time it is compressed. I popped the lowers off again, to inspect for a broken foam ring but it was fine. I also replaced my dust wipers using the seal driver tool ensuring it was flush. At this point I don't know what else could be wrong. At best, I wonder if it is the residual oil wrong the foam rings as I did use the soaking method to pre-oil them and I did not squeeze any oil out before installing them. Any ideas?

[@KrutonSalad16]

I have the exact same issue with mine. No idea why either. I used the soaking method as well

[@dinunclv]

Is it OK to use chain cleaner? Is it necessary to use suspension specific grease or can I use any grease?

[@gabeah]

suspension specific grease is formulated to not harm the seals and to be compatible with fork oil.

[@melvinjohansson988]

I'm thinking about getting those rubber covers that you can find on older bikes and to somehow put them over my suspension. Is that a bad idea??

[@hugegoose5004]

Nope, as long as it doesn’t scratch the metal, you can use a rubber boot or a neoprene boot. I like the neoprene ones but you just gotta make sure not to let them sit wet/dirty on the stanchions or they will do more harm than good.

#AskGMBNTech This is very relevant to your video. I've got a 2016 Fox34 Factory Series. Can I use any type of suspension oil/fluid, example: motorcycle suspension oil as long as they are the same weight? Reason I ask is that Fox specific oils are very hard to come by and are very expensive whereas there are a lot of motorcycle workshops near where I live and they have various suspension oils for various motorcycle forks

[@paradox963]

What you want to do is not match the Wt of the oil but the viscosity that is measured in CST for example. Fox Fork 20Wt Gold bath oil 98.9cst @40C / 13.6cst @ 100 C ===> Elf 20 W fork oil: 99 cst / 40 C - 14.6 cst / 100 C Fox R3 5W (damper oil) 15.8cst @40C / 4.07cst @100 c ====> Maxima 5W 16.2cst / 4.4cst

[@shafhamid83]

@@paradox963 see I always thought that the oil weight WT, sort of indicates the viscosity of an oil and anything labelled 20wt or 5wt can be used on my Fox fork. From what you've stated, other oil cst numbers are different from the Fox oil but would the difference be a big deal? I live in Malaysia (it's hot & humid) and I can easily go into a motorcycle workshop, a petrol station or a hardware store and buy 20wt or 5wt suspension oil from Elf, Motul, Maxima, etc. They're quite affordable whereas it's very difficult to source Fox specific suspension oil and if I could find it, the price is 3-4 times more. Also when I say motorcycle, in Malaysia they're mostly scooters & mopeds (100 - 125cc engine types) and there are a lot of them around. I think that's why it's easy to get motorcycle suspension oil in the market

If you can afford the oils, tools and seals then you can afford new crush washers for a few more pennies. No point doing half a job. Also cleaning and regreasing the air side will only take an extra 10-15 mins so should do that while the lowers are off. 👍🏽👍🏽

[@mrbadger9920]

This is a job I have been putting off as I thought it would be too complex but you've given me the confidence to go ahead with it. One criticism though is your use of the torque wrench. 1 click only. Clicking it multiple times was just over torquing the nut, you could see how far extra it moved afterwards

[@mattgies]

While we're talking about how to use a torque wrench, that's also the wrong grip. By putting his thumb on the opposite side of the wrench, he reduced the amount of torque transmitted to the fastener. You should use an open grip on only one side of the handle.

[@morperformance]

On the newer forks with the air bleeders, why can’t you just remove each bleeder to drain and refill the oil? I figure you can remove the bleeders, put the fork in the stand and angle it slightly so the oil runs to the bleeder holes.

[@Adam-vm8kp]

A lower leg will benefit from clean foam rings and clean grease packed seals just as much as fresh oil. You want to get as much dirt out as possible.

I mean... you can. But there's not really a reason to

[@richardjohnston6688]

I'd rather sand it with sand paper rapped around and ice block stick in a more concentrated area. You will be there for ever with that sanding block . It would be to easy to sand were you don't want to sand . Just use the file get it close finish with sand paper . Anyway why didn't we see the finish product to see how good it was.

Can I use a heavier weight of oil for my forks as I am a heavier rider? In Motocross we can , but not sure about the bikes. Please help! Thank you. Fork is Rockshox Judy on 2021 Giant Talon 1. Thanks from Raleigh NC USA 🇺🇸

Yes you can. I use a lighter oil in my Fox 32 Talas and it works fine. But you got to check some things out before you do this. Be aware that you may loose your warranty. The stupid measurements in Weight e.g. 10wt don't mean anything. Instead look at the viscosity in cSt as well as the viscosity index. The index shows how constant the thickness of the oil is. So you might want to select a oil with a higher viscosity, but about the same viscosity index.

@@michaelfauter3318 I am sorry for the late response, though I truly appreciate the advice! Thank you for answering my question as this now will help tremendously. I will try this ! Can't wait! Hopefully will do a fork upgrade soon.
