are you guys talking about just the free-hub bits, or the bearings, or both?

What other free-hubs need regular lubing?

Plastic bushing at the freehub's base. When it gets dry it gets noisy and stops freewheeling. Original freehub had a bearing there, new one, in an 'attempt' to save weight went to the bushing. Over time it also gets out of round. That plus only 2 pawls makes me wonder why they use such a cheezy hub on wheels that are $1000++. Other freehubs are generally 2 cart bearing/3 pawl freehubs. Occasionally the bearings go south, requiring replacement. Yes, the OVH doesn't take very long on Mavic freehubs but I think, from a company that used to be known for superior hubs, this is poor form.

Their 'fix' are harder pawls(new red ones) as they think it's 'pawl dust' that's causing the problem. A Mavic outside guy suggested a .5mm spacer under the freehub body along with the supplied 1mm one. This works really well as it raises the freehub a wee bit off the draggy rubber seal, along with frequent cleaning and re-oiling.

5w-15 i think. I dribble on quite a lot. Onto the seal, onto the freehub bushing itself and pawls. Don't store the wheels on your white carpet cuz it dribbles out a bit. Don't use grease. That seems to make the draggy-ness worse and if it gets onto the pwasl, they can stick down. Little whimpy springs.

thanks

Sounds like another one of those silly modifications which makes the production less durable, only to save 40g

The Mavic instructions say 10-20 drops - with automotive oil, you may want less.
