    Default Noisy Shamal Shimano freebub - easy to lube?

    While coasting, my Shamal Shimano freehub is pretty noisy. Sounds kind of dry. Is just adding some grease to the pawls very involved? One video I just watched showed only one 17mm locknut needing to be removed to take off the FH. I'm not thinking of replacing bearings or anything. It's a pretty new pair of wheels (c17 version). Just want to add a little grease to quiet things down.

    Am I missing something?

    Thanks.

    yes, it's that easy.

    dont use grease. use a heavy weight oil. I use moto hypoid gear oil in freehubs, since it's literally made for sliding contact surfaces, but any good heavy oil will work. NFS would certainly be acceptable. clean everything really, really well first. it's a pretty simple job just to clean and lube the mechanism.

    Thanks for the reply. I am wondering about what lube to use, though. Agree heavy grease is out, but wonder if NFS grade oil is best, or something more like light white lithium grease or something. What was on the pawls when I removed the freehub just now is certainly heavier than NFS.

    Edit: I'll give NFS a shot for now. Don't want the pawls sticking, for sure.

    What to get fancy? Smear a very light coat of NFS Race Grease on the clean assembly including pawls than wipe (not drops) some NFS chainlube onto the assembly. It will be dead silent. For the record Race Grease is specifically made to be freehub/pawl safe.

    Pay attention to the direction you need to turn the nut to loosen it (clockwise) while holding the axle stationary with a hex wrench. Directions are the same Campy or Shimano compatible. See below. When reinstalling the freehub, use the end of a flat screwdriver to depress each pawl while applying gentle pressure to the freehub body and gradually work each pawl into position on the ratchet teeth so the freehub slides into place.

    Yup yup, little dab of nfs grease and a teeny bit of nfs world's best chain lube is the ticket.

    On Campagnolo freehubs, at least most of the ones I own, there’s a little (2 mm hex) grub screw in the middle of the the freehub. It does not hurt to occasionally remove this, dribble in a few drops of NFS, and reinstall.

    That disappeared about 15 years ago when the freehubs went from a two-part (steel or Ti pawl carrier screwed onto aluminium frehub body) to a single-piece aluminium.
    The latter, though, are much easier to replace a bearing should you have to; but bear in mind the pockets for the pawls will "give" over time and you'll have to replace anyway.
