You missed something. Service should include taking out the seals so you can also pull the plastic sleeve bearings. Seals slide out with encouragement from a flat blade screwdriver. Then reach down inside the lower and work out the sleeve bearing- one per side. The sleeve bearing is what actually contacts the stanchion. It MUST be cleaned and relubed. just dabbing grease down in there with a stick is not enough. Clean the seals too. As an annual service you should clean and lube seals and sleeve bearing, clean stanchion, but don't bother with all other stuff. The spring doesn't care if it has fresh grease on it. The way these forks fail is wear or corrosion of the stanchion, and that is controlled by seal and sleeve bearing. In your 2014 video servicing a Suntour T890 fork, you did get the sleeve bearings out and cleaned. The sleeve bearings are a very similar design to what I found in my ~2013 XCR 29er.

Man ! I swear your video is precious as hell. I'm from France, bought a rather old bike sold by a huge sports brand that has this exact same fork. Unfortunately, they don't provide any tips to clean and service this fork, so I had to scatter all around the web to find how to service mine correctly, and I found yours ! Again, keep going with your videos, you're awesome, and you're helping people all around the globe !

Dude thats the best ON BUDGET fork. I have been using it for like 3 weeks now. Im always on the road traveling from house to farm. The mechanic tinkered my xcr from 120mm stantions to 150. Man its a boost. I only spent $40 for everything including materials needed for the extension of the stantions and mechanics' fee. The best fork for $40. 👍

Thank you for this tutorial. I just completed this maintenance with your guidance on my 10 year old Rockhopper. It gets new brakes in the morning.

Really chuffed I found this as my forks are seized and now I know how to recon the unit. Really useful video. Many thanks for sharing 👍

Always good to see these videos in your library, very handy to have a reference should you come across them...

Thank you! Just successfully repaired my XCR today. I had to wait for the wrench & grease which I bought online but once I had them, it was a breeze. BTW, mine didn't have the lockout. Both just had the same pre-load dial.

Great video, didn’t realise my fork was so simple and straightforward, think one I can tackle myself. Thanks!

Good video, very straight forward and informative. But there are two things to point out You should not use a metal hammer to tap on the screws at the bottom of the lower or you risk damaging the dropouts, and make sure to remove any preload from the coil before dissasembly/assembley. Thank you for another video.

Great job, RJ! I've just come by these forks, 2006 I think, so will be following your plan! 👍🏻

Thanks so much for this detailed explanation and tutorial! Exactly what I needed to know for the maintenance on a bike that I bought for 20$ on eBay. Take care and stay healthy 🖖💪👍🌞

Thank you RJ! I was scared to disassemble my fork suspension cause I'm afraid I might mess up something this tutorial of yours helps me a lot for future maintenance

I’m not a mountain biker but I enjoy your videos anyway. They are always informative

Thanks for the video. I have looosened the caps with pliers instead of special tool. I was gentle and have not damaged the caps.

Good video and explanation!, I service motorcycle forks normally but just had a look before stripping my son's XCR forks for a clean and grease.

Great video. Thanks RJ. I just finished overhauling my XCR forks. AAA+

Excellent Video. With all the extras (helpful hints) thrown in.

This is very informative video on this kind of forks! I acquired one recently and wanted to do it myself as the brand has moved out of India. Good luck for more videos!

Thanks for the great video I just used this as a guide to help service my forks. Thanks again
