Freewheel on Mavic SSC-SL turns with tire/wheel rotation

I am trying to determine how to properly lubricate (maybe disassemble) my rear wheel hub. When the tire/wheel rotates the freewheel and chain will rotate (if I'm not clipped in). I believe that my Mavic SSC-SL wheels are about 2004-5 vintage and are in great shape. I have removed the cassette and need to know if I need to further disassemble in order to better lubricate. Bearings appear to be good as there is no noticeable friction/grinding when the wheel rotates (I held the . On the freewheel side of the cassette, it has a 5mm allen wrench fitting; on the non-drive side, there is nothing. I may need an axle vise to remove this safely. Also, to lubricate would I use mineral oil (Mavic recommends mineral oil I believe) for wheel bearings. Any help or advice would be greatly appreciated.

Best Regards,
Bill Cranston

    Corey, Thanks very much for your reply. It was spot-on. I eventually (over Thanksgiving) figured out the 'tough' part for removing the 'dust cap' or whatever it's called on the non-drive side. Once that was off, it was a breeze. I had printed out the Mavic manual and it was not clear. Thanks again for your help and follow-up - it is greatly appreciated.

    Regards,

Not sure if you ever got a response. I can help with half the issue. These Mavic SSC-SL wheels are a breeze to disassemble the rear hub (I've done so many times). I have these wheels on road bikes AND cross bikes. You DON'T need (nor want to use a vise). Yes, the one side is a 5 mm allen key. While the other side seems like it has nothing, you can actually (with your hand) simply grab the black axle and pull it away/off the hub. It will be a bit stubborn, but trust me, it comes off. There is an O-ring on the inside that simply keeps it sealed and on. Once you have that part off, you now insert a 10 mm allen key. With the 5mm in the other side, you can now twist and remove the entire axle and freehub. Careful, the freehub will now come off the axle, exposing the seals, a washer, AND 2 pawls that are in place by springs. Be careful not to lose the springs.

There's not much to it. Now simply inspect, lube and reassemble. Btw, this is also how you change your wheel from a Shimano hub to a campy hub.

Hope that helps.

Regards,
Corey

Can you help with this problem? When descending at fairly high speed if I freewheel at all in any gears below about 23 tooth a really awful screaming noise is heard from the rear cassette and the chain jumps all over the place. There are no other problems with the gears i.e indexing skipping gears. Thanks.

Replaced freewheel hub body on rear wheel ultegra wh-6600, cannot get wheel running, freehub will not run smoothly, even LBS cannot fix and have no ideas. Wheelset only 2 years old and cost 350 quid....


If the lbs can't fix it you could send it back to the manufacture. They will fix it. But keep in mind that if it isn't under warranty it might cost more to fix than replace. Good luck.

Cant put my mavic back together properly


It sounds like you lost the washer that sits between the bearing in the nose and the freehub bearing. If you lose that washer, when you re-tighten the axle, the two bearings will bind and prevent the freewheel from spinning easily.

Take your freehub off again and see if that washer is there. If it isn't, you'll have to get a new one and replace it. It's easy to lose that thing if you don't know it's there when you take the wheel apart, because it'll just fall out.

When I reassemble those wheels. I thread the drive-side axle through the freehub body, then place the washer over the axle on the inside of the bearing, then thread the axle through the nose.

Also note that if your freehub seemed loose, it probably needs to be replaced. The FTS-L freehub body used on the Ksyrium wheels uses a nylon bushing as the friction interface to the nose, and this bushing wears down over time even with good lubrication.

No big expense, I'd remove the back tire and then take apart the rear cassette and axel. I expect it will require a good cleaning and new lube.

In every gear if I hesitate pedaling when I resume there's free play for a quarter turn or so and then it will resume normally. This happens repeatedly whenever I 'coast' even for  moment


Hi,

Your free wheel assembly has play and simply needs to be reassembled. It is not an expensive fix if you wish to take it to a repair shop, or if you are mechanically inclined, you might wish to disassemble the rear wheel drum assembly, which includes the freewheel assembly and the gear spindle.

If however you do not feel confident in this procedure, you might opt to have a repair shop handle it. It is possible they may find a worn part in the freewheel assembly, but as stated before, most parts in the assembly are inexpensive.

Hope this helps. Thank you for using FixYa.

Squealing noise for no apparent reason rear wheel when freewheeling


Could be a bearing..
If there is a grease fitting - try pumping some grease into it..
Other than that - try some penetrating oil or white lithium grease where the bearing are..

Noise from ksyrium back hub


The mavic hubs need to be disassembled and cleaned/lubed every few thousand miles. I suggest you take it into the local bike shop to have the work done unless you are a fairly good mechanic. It is rather simple to overhaul but it could be a headache if done incorrectly.

Hope this helps!

Noisy Rear Mavic Ksyrium Hub


Sounds like a road wheel with a worn FTS-L freehub body. You'll need to have it replaced.

What happens is that the nylon bushing wears, causing there to be play between the freehub and the nose of the wheel. Once there is enough play, the freehub can actually vibrate against the nose, causing noise and friction - which is why you see the chain slacken. This is commonly called the "squeal of death," meaning it is an indication that the freehub body is "dead."

A new FTS-L freehub body should be about $50-60 and shop shouldn't charge more than about $20 to change it out. Just be sure to tell the shop one very important thing:

"Do not lose the metal washer that sits on the axle between the outer bearing of the freehub body and the outer bearing of the nose of the wheel!"

This is so incredibly important - but time and time again, shop mechanics will lose this washer before they reassemble the wheel, causing a series of nightmares with the wheel.
