fox 36 perf elite knocking

[@randommtbridr]

I got the same issue, I’m guessing that its the negative pressure chamber.. because my 36 rhythm fork got a little bit of suction too (apart from that knocking)

@imdoodrandom mine was either the damper or bushings. Fox refused to admit something was wrong so we changed both and it was gone..

Sorry man! Defective product! That's some gnarly loose/out of tolerance bushing play. Get that in for warranty @Fox

[@Ignitionmtb]

Hey, it would seem so! I've already sent it to Fox NZ and the reply was this as comments: "pulled damper cart, greased IFP, new fluids - all fine". The Airspring doesnt look like its been pulled and i believe its in the Airspring side based on how much you can feel it when holding that lower if someone else compresses fork for me. Will ring them tomorrow and see if i can speak the guy who worked on it.

@@Ignitionmtb Hmm that is a weird sound. Well, the first time I listened to it was on my phone and I hear it better now on my computer... It sure is an oddity. You ensured is not a headset thing? Hearing it better still makes me feel like its a bushing thing... I wonder, if when you send it in for service, they do not install the fork to a bike to ensure it is 100% good... they do the best they can up to that point... so some things/sounds are not easily replicated when the suspension device is out of its natural context.

@@Headlessthirst hey, the LBS fully tightened the headset to basically not turn the bars, and checked still there, Tried pushing on the crown to eliminate headset while in bike but still there, turned bike upside down and pushed on lowers the same and same sound. Removed fork, installed stem and bars, pushed on fork and still the same sound. Spoke to a tuner and agrees that not a headset sound and is something to do with bushing or something. Theres even a moment in the video i pulled the brake and tried to rock the headset but nothing came of it.

@@Headlessthirst see the other video i just uploaded to confirm

​@@Ignitionmtb it's normal ?

[@turbulentFlux]

hi, have you found any fix for this or did it worsen over time? I'm facing the same issue on the same bike

[@Ignitionmtb]

never really Got to the bottom of it, It went to fox 3 times, finally gave in and sold it. Bought a factory 36 that felt really good for the first ride then it did the same... They put all new internals in the factory fork and it seemed better, was still noticeable but ive learnt to live with the fact Fox stuff just isnt that great - they just have a good damper. Fox stuff rides pretty good but just QC is a bit meh, Like the Float X knocks, x2's blow up and break, their forks knock...(their CS in NZ is also Terrible as they argued with me on the phone about this) - every other suspension place here said its NOT normal. Ive had alot of RS stuff - never had an issue with the Super deluxe, lyrik etc, I've only had to replace one CSU that creaked on a ZEB(warranty without arguing)
