I’ve had a set of Mavic Aksiums for a long time knocking around in the garage for ages. I’d not really used them in a long time, but decided to get them ready with a service and a couple of rides, as they make great winter wheels.
So, service time it is. Mavic freehub designs are a little different to the Fulcrum wheels I normally use. The drive ring is internal to the freehub shell, with the pawls on the drive shaft. I started by removing the drive end cap, and pulled off the freehub. Mavic hubs are known for the “Death Squeal”. Caused by the large plastic washer that presses against the hub shell.
You have to be really careful pulling the freehub off, the pawls and their springs may fall, they are not secure in their mounts. Take them out and put them to the side.
So, after the freehub is off, clean both interfaces of this washer, and check for wear. May as well check the bearings while your at it to make sure they spin freely. Clean all other parts. Don’t use degreaser near the bearings, just wipe everything clean. Mavic use a very light oil in their hubs, making it easy to clean up.
There’s many, many threads on what oil to use when lubing Mavic hubs. Of course you can use the stupid expensive Mavic oil, others say use gear oil, sewing machine oil, mineral oil and all manor of other oils.
I used bog standard chain lube. The finish line wet lube. It’s just liquid enough, but clinging oil. A drop on each pivot point of the pawls, smeared on the nylon washer. Putting the pawls back in, the small springs must be on the tiny post on the pawl. Rest the end of the pawl in its cutout, and make sure the other end of the spring goes into the depression on the hub.
To get the freehub back on, hold the pawls in, while lowering the freehub over them. Gently rotate the hub to make sure everything is seated. Re attach the cap, and done.
The Finishline lube I used has the added advantage of making this hub virtually silent. That’s something I haven’t experienced in a long time.
While being a cheap set of wheels, they are not a bad set of wheels, and are great for a set of winter wheels, commuter or just budget wheels.
