Lube or grease for free hub overhaul?

Hi - I am overhauling my Fulcrum Racing 5 free hub. I have been reading that heavier grease is not recommended for the free hub paws / splines they interat with.

Can anyone recommend the right type of lube/grease to use? After reading some other forums, some people have used these: Dumonde or Philwood

any recommendations or advice would be greatly appreciated. thanks!

They come from the factory with a light lithium grease. Anything is really fine as long as it is relatively low viscosity (not very sticky) and you apply it sparingly. You don’t need a lot of grease on the pawls. Thoroughly clean out whatever is in there before reapplying.

You can also lube it with an oil like in the links you posted, but the freehub will be a bit louder and the oil migrates more than the grease (grease stays in place a bit better).

I'd probably put Phil's oil in if I needed to re-lube a freehub.

Note that "if." I've never needed to re-lube a freehub.

I just ordered a tub of Shimano Free Hub grease as I've got two free hubs that need servicing. $16 should last me a lifetime.

Fulcrum recommends greasing the pawls & ratchet ring with lithium grease. Funny thing is that tube of Campagnolo grease in the picture is Kluber Isoflex Topas NB-52 grease which is a barium (not lithium) complex soap.
