Older Ksyrium freehub service

At the end of a long ride the other day, I noticed that when I backpedaled just enough to put one pedal at the bottom of the rotation, I could feel in both pedals and could hear a very loud noise. It sounded like something touching the tires and scraping. Inspection showed nothing hitting or touching. It seemed to start more easily if I backpedaled fast to get to the right location. It seemed a little stronger in the drive side pedal
Nothing touching anything. If I just stopped pedaling and coasted nothing happened until I backpedaled just about a quarter turn f the crank.
Last night I took the wheel and the cassette off to examine my old first generation Ksyruinm hub. Built this bike and bought the hub about 2003.

Suggestions?

How to take this hub apart?

Very easy. I did it two months ago.

13 years without servicing the freehub is a long time. Go ahead and do it...

Ksryium freehubs have a nylon bushing which wears. You can replace the bushing or the whole freehub. It is probably a good idea to replace the bearing as well as the bushing. I just replaced the whole freehub as it comes with a bearing and bushing. Either way - new freehub or rebuild your own. Less expensive if you shop around but for reference....I used the video below from Rogue Mechanic to teach myself. The most difficult part is making sure that the pawls and springs don't get lost and that they are installed correctly. Otherwise extremely simple. Shimano hydraulic brake fluid works for the mineral oil lubricant.

Part 1

Part 2

Thanks for the video and the links. Neither one matched what I had. I figured it out anyway.
There is a round spacer with no wrench flats on it, on the non drive side. One needs to hold this with a rubber cushion and huge channel locks to keep it from spinning when unscrewing the allen socket on the drive side. Thanks again.

Channelock pliers are not part of servicing Mavic wheels.

Pull the end cap off the end of the "round spacer" and insert the appropriate sized Allen wrench into the "spacer". That is the proper way to do it.






The 2003 service manual is at https://roguemechanic.typepad.com/rog...Mavic_2003.pdf.

If you are going to ignore advice then why bother asking? Nobody is going to want to help you and good luck moving forward.

How is it possible to ignore advice when the job was finished before the advice was posted?

Try to keep up.

Why ask for advice if you are not going to wait for the advice before you do the work?

This whole thread is waste of time because you are not interested in doing the work correctly anyway.

Good luck.

So If I ask a question while having my morning coffee. I need wait as long as it takes for someone to respond?
If I can't get to my email until evening, I need to do nothing on my own? Everyone should do this? Some answers take longer than a day, or days before a response.

Welcome to an internet Forum. Try to understand how a forum works. Maybe decafe would help.
