Fix sinking office chair | Testing the WD-40 idea 

I had just gotten a PVC pipe an hour before seeing this video. I youtubed that PVC pipe video again for the instructions and while looking for it I chanced upon this and saw the WD40 in the thumbnail. I read the positive feedback in the comments and was convinced to try this out first since I had a can and the tools needed atm. I do not understand the science of using something greasy to fix something that is slipping but lo and behold, it mvtherfcvking works!

It worked like a charm. I would recommend putting down a drop cloth or some newspaper before you get started. The washers are greasy and will stain your carpet, not to mention the dripping WD-40. I wiped off the excess grease and grim from the parts. Everything seemed well-lubricated. I wouldn't hesitate to use some new grease if I had some. Don't poo-poo Vaseline. That put a rocket on the moon. Had a little trouble getting the spring clip off. Ended up using a small screwdriver and needle-nose pliers to work it off.

This is really a very quick help video! Thank you so much! Stay being blessed and a blessing to others as well☺️

The slow motion sinking part, was all the money!! Hilarious!!

Maybe turning the chair up-side-down would lubricate the shaft all the way to the top and have an even better effect ? Thanks for the post 👍

I was thinking of getting a new chair for a while because of the sinking problem but I gave it one last chance and looked up the problem. Found a lot of videos that fix the chair in one height before I saw this one and gave it a shot. Worked like a charm and took maybe 2 minutes, TNX!

"Vaseline on the shaft" I'm dying from laughter watching these videos. It's too funny. I'll try the WD-40 idea and see if it works for my chair. Thanks!

Thanks, this TOTALLY fixed my chair, which is less than two years old. I was very disappointed to have bought this chair, for it to begin to fail like this so soon. I tossed my last chair for this very reason, and now know that i could have possibly fixed the problem as simple as this. * * * * * * I am adding this post script three weeks later. My chair began to drop last night in little bumps at a time until it was all the way down in about one minute. I am going to repeat the oiling process once again, but this time I’m not going to use WD40, but a light machine oil. I’ll post my results later.

The fix worked like a charm, thanks for the video.

It worked perfect for me the first time I raised it back up!! AWESOME!! Thanks Dude :)

Your office chair fix worked perfectly!! I used lithium grease and I am excited that it is finally fixed!! Thank you!!!!

Yup, that's all there is to it. You'll want to invert the chair fully, and get any oil in there that you have to hand. Hydraulic, ATF, gear oil, even baby oil, pretty much anything except brake fluid. I wouldn't recommend vaseline for use on rubber seals: silicone, lithium, or red rubber grease would be better. If you remove the chair from the base, there's another seal at the top end (under the release button) which you can also lubricate with liquid.

I have a AkRacing chair since years and the last couple months it was sinking randomly, it was so random that i didnt ever bother to fix it, but last couple days was terrible annoying. I was looking prices to buy a new one, because i dont want to change the air compressor. I reach to your video and did this because i have wd40, and... DONT UNDERSTAND WHY, my chair problem got completly fixed, i really really really appreciate for this tutorial man, u save me lot of money.

Makes sense that lubricating the O-Rings that connect the shaft to the pressure chamber is the easiest problem to fix. Nice to see that the likely cause is the seals drying out and just some lube will fix it. Reminds me of power steering pumps on my 85 Olds, the seals would dry out over time and to fix it you would put a greasier oil into the power steering pump to "moisturize" the O-ring on the shaft that connects the pump to the motor.

It works! I made sure to use plenty of WD-40 until no more went in, and all seems well now. Thanks very much.

Fantastic! My chair would randomly drop in small but startling increments. I was ready to go get another gas piston when I found this video. I used 3-in-1 oil, and it took about 10 minutes to complete the job. So far it looks like the issue is fixed - my chair hasn't dropped at all since. Thanks a bunch!

I tried your fix after being driven mad for 2 days of my chair sinking and happy to report it as worked so far :) So thank you so much.

This works great most of the time only problem when I lend back it drop every time. Thanks for the info.

It helped a little bit with my chair. My chair drops when I sit on it but doesn't really sink much after I'm sitting on it. Adding some cheap grease I got from china a while back seemed to help it keep it's height better and is much more springy.

Used this video about 10 minutes ago to fix my sinking chair. Great idea! Thank you.

I used sewing machine oil on my chair's sinking piston. It dropped the first couple times after the lubing. I repeated oiling once a day for two more days, ran the piston through its full stroke a few times, each time. Now weeks later it seems to stay working with no more maintenance required. Excellent!

I have watched several other RU-vid videos on this subject and considered several options. I finally settled on the cheapest; a radiator clamp around the piston with duct tape protecting the piston, which made the chair non-adjustable, but worked. Then I came across your video and tried your method (I have some WD-40 silicone spray that I use for lubricating window channels in my car), and behold it worked just great. Thank you.

It worked! Thank you so much!! Who would've thought lube would help it stay up!

I used 3-in-one oil because it's a little heavier than WD40 and it fixed this problem immediately. I only had to do it once and I had the chair upside down so the oil ran down into the cylinder. Thanks for the information, it fixed an annoying problem.

Used vasoline, it worked. Thanks for the free fix.

Worked as a charm. Thanks!

This worked. First treatment. Surprising!

Bro - it worked! - thanks a lot man

Awesome! I'll give it a try, thanks.

I give it a like and subscribe because I believe WD-40 no matter how simple of a compound it is will fix almost anything. May even be the Cure for Cancer one day. Stranger things have happened. LOL. Thanks for the video.

Now I'll have to send my Amazon replacement shot back. I should have watched your video first. The one I watched before yours said to replace the old shaft. And I could get the old shaft out of the chair base. I oiled and hammered twice. Your method worked instantly! Merci!

My chair also got fixed with this method. To my surprise, the chair sank exactly as shown in the video 2 times post fixing, but after that its stable now :) Thank you..

IT WORKED!! THANK YOU!

Ok... I followed other guides using ductape and hose clamps and I'm pretty angry that the wd 40 solution wasnt one of the top like 10 videos. Thanks alot for making this. I used Vaseline on mine which is probably not better than WD 40 but this actually worked. I do not understand the science behind it though. Thanks a lot man.

Worked for me. I used 3 in 1 oil on mine and it worked also for me.

It worked man! Thanks!

That worked for me! Definitely wasn't expecting!

Worked for me!! Thank you!!!

thank you very much

It works by filling in air gaps that are made from the original oil wearing out and it will only work if the inner seals are broken, if the outer seals broken you need a new cylinder as the gas escapes.. works best if you remove the whole cylinder and fill both ends moving the cylinder in and out

is working for Me! THANK-YOU

I think it helps restore the seal in the cylinder! I will try this!

I will try thanks for the video bro

God bless you, sir.

Just tried it so far so good.

This works! Thank you so much!

I'll chime in, I used CRC True Tap cutting oil (for drilling steel) worked like a charm.

Maan I was so skeptical about this, but I had to try it because I spent $400 on a computer massage chair, and after 3 months mines started to sink, and I'm a very slim person so its not even about weight. I followed your instructions, but i used the 3 in 1 oil, and I can't believe it worked...OMG thank u so much. I would have thought that grease would have made it go done even faster instead of staying up lol

Too simple vaseline worked a treat, great tip.

WORKS!! But I used "tri-flow" instead

Some guy said to just turn the chair upside down ver night in the DOWN position. In the A.M. before Turing the chair over extend the the chair a few times.This should make the oil in there work again. In another hr. turn the chair back over after leaving it in the upside down position with it back DOWN again. in an hr. move the seat to the most up position & then turn it over & see if it stops falling down

It worked, thanks!

Clean shaft then lubricant. Works perfectly!

So does the shaft seal dry out and the lubrication allows the seal to expand and work like it should?

I used tire black as it is thicker. It works as well.

Update: It did fixed mine. But I have 2 chairs and it worked properly only on one of them. Will try again on the second one with grease when I'll have time

I packed automotive grease on it and it works like new thanks buddy

i tried the same from a different video, at first it was working, and it was fixed for like 2 and a half weeks. then it started happening again, and now even if i wd it it sometimes works sometimes does the same thing immediately

This actually worked. Let’s see for how long! :D

For some reason this seem to have fixed my issue as well. Already bought a new gas cylinder but can’t remove the old one so I tried looking up for some other fix. Could’ve saved a few money if I only saw this video before buying the replacement cylinder.

After watching the other video using WD-40, I tried. The first time, it did not. My chair sank; then, I knew I did not do something right. I remembered seeing WD-40 fluid disappeared near the bottom of the cylinder. So disassembled, sprayed more and pushed the stem a few times; i repeated a few time just to put more fluid inside the cylinder. It worked.

Worked for me thanks.

Works

Yeah you have to lube the shaft good and move it up and down a few times, then it will stay stiff for you.

Thanks for the video, just tried it with some white lithium grease, we'll see how long it last but it seems to work.

It work 100%

Great. Thank you. RR

Great comedy moment starting at 3:10 😂

You MUST of learned this from USAF basic training! This is some pro level life hacking. TYVM worked like a charm with some 3-1 in the hole and packing with Petroleum Jelly. THANKS!

I used bicycle chain lubricant and it worked great. I think it is better than WD 40 cause it is more greasy. Thank you by the way.

Ngl, thought it was going to be bogus, but then I saw it work in the video. Still skeptical, I tried it myself, and it works! WD-40 fixes everything!

Just tried it. Hopefully it stays up. :)

thank you bro

chair sinks even more now :') thanks

Wow it worked....but why did it work? Thanks for the video!

It seemed kinda counterintuitive to me, to "lube the shaft" 🤪, to KEEP it from slipping, but it was, by far, the easiest & cheapest thing to try first. I liked Randy Moberg's suggestion & used the lithium grease I'd bought to solve the chair's squeaking. I didn't even removed the base of the chair. I just laid it on its side & sprayed it directly on the steel cylinder, around where the 2 parts meet, flipped it back upright & raised & lowered it a few times. It worked beautifully! I'll just wait to see how long it lasts.

use white lithium grease in a spray can right next to the WD

thanks

I've got PB Blaster I will try and post results later. Did see on another video after spraying wait about 30mins. Setting time I guess.

Happen randomly to me too but only when I sit in it after no usage of a while, this could fix it ?.

!! PROBLEM FIX !! Ig you remove the clip from the bottom of the cylinder and pull it out you can check if the rubber gasket (O-Ring) is broken :) The ballbearing and rubber gasket was broken on my chair and the crack in the gasket was letting the air out the bottom of the cylinder.

Just applied the fix, so far slide down about two times now is holding up, fingers crossed we will see…

Damn i just bought a new cylinder. Guess im sending it back

WD stands for Water Displacement, not lubrication.

worked perfect with vaseline

This worked great. Can any engineer (or someone smarter than me) explain how this fixes the chair? I dont even understand how it really works, but their was some black grease in their after my gf built this chair. Anyways wd40 did it

A hose clip or 2 works permanently

I just tried this fix with a mixture of WD-40 and Vaseline, because some say that WD-40 by itself is a bit too thin and oily. So, hopefully it works.

can you adjust it to move up and down after spraying wd40?

I would probably want to put a towel down before spraying that straight down lol

can someone explain why we need to lubricate that area? It worked btw, thanks.

that face you made when you were sinking lol

I fixed mine. Vice grips. problem solved

Held my can firm and gave my oil a good shake, lubed my shaft all over and sinking cylinder dysfunction sydrome is a thing of the past for me. Just a shame i was all done in a couple of mins 😂

Didn't work for me

Hmmm not sure how that would even work, however I could speculate that the WD40 is maybe blocking an air gap that has appeared between two worn washers. Anyhow I haven't even removed the base of the chair I've just sprayed it directly on the cylinder itself to see if it runs down onto the washers, be one hell of a miracle fix if it really does work though :-)

Well I’ll be damned….thanks!!

Thanks worked for me. No it didn’t, but thanks.

Next time turn chair upside down so oil can get into shock work better

You don't need these fancy products, cooking oil works too
