    ways to tell if hub needs regreasing without taking it apart?

    since shimano is obviously nuts when it comes to their ideas on hub bearing adjustment (been adjusting my rear hub for over an hour now) i'd rather not take apart my front hub to find out if it's dirty.... so...

    1. doesnt run smoothly (eg gritty feeling spinning the axle)
    2. play in it
    3. too noisy?

    I vote for #1 and #3 and raise you some red/orange/black stuff coming out of the hub.

    Spin the hub between your fingers, if u feel like there is loose rocks grinding inside, it needs a rebuild.

    A front hub adjustment should take all of 2 minutes. Practice more.

    If you have been working on this for an hour, it's fairly obvious you aren't sure how to do it. Read Park Tools web site on hub adjustment or take it to an LBS for a lesson.

    Complete overhaul of a Shimano hub, including disassembly, cleaning, repacking, reassembly and final adjustment should only require 10-15 minutes.

    One big help is to clamp the wheel in an axle vise held in a a bench vise. This holds everything steady and makes the adjustment much easier to determine.

    Yeah, practice makes perfect. Sidle over to the LBS and give em a six-pack in return for letting you watch them adjust the hub.

    Hubs that need repacking are immediately obvious once you spin the wheel while holding the axle. Grittiness = repack.

    i did use the park instructions. they're one of the reasons it always takes so long.

    adjust it, stick in the frame, flip the lever, if it ain't adjust right repeat... blah blah blah.


    anyway, if i wait till i feel grinding would that be a point at which the hub is damaged?

    I usually either go with the "Sheldon Brown method":
    Use a pair if suitable spacers to simulate fork ends and still let you get to the cones to adjust. Set them so that they bear on the ends of the axle, rather than the locknuts. Sheldon used a pair of old cones with cut off stubs of axle threaded in.

    or

    Adjust so that they feel right, then back off 1/8 of a turn. Is usally spot-on when I put them on the bike.

    I took my commuter's hub and rebuilt it after 15 years old shimano 105 1055 series. It was totally unnecessary the grease was in fine shape as were all the bearings, axle, and cones.

    In my experience, yes. The other descriptions of when the hub needs servicing sound more like when it needs replacing, or at least needs new cones. Other than that I'd agree with what's been said already, but I would add that to really feel the bearings you should hold the wheel stationary and turn the axle between your thumb and forefinger, as though you're a safecracker.

    Probably not a good thing to ask for unless you know the mechanics really well.

    Ask em
    This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
