    Fox 40 axel bolts

    How about the 4 bolts holding the axle (and the axle) on the fox 40 fork?

    Fox says they should be torqued at 19 in-lb but when I do this I can feel a play in the frontwheel but when I torque them a bit more then 19 in-lb the play stops........how accurate are you about these torque settings?

    Thanks!

    Try to torque down the axle more, and then torque the other 4 bolts down to fox's specifications. It really shouldn't matter that much what they specify, but if you are worried, clean up the bolts first with a little lube, then torque to (a more accurate) 19 in-lb.

    But really, no wheel play is more important than torque settings. So tighten the axle down more, then torque the 4 bolts down to about 19.

    EDIT:

    Yes, on the 36 for sure, and 40 I would assume. Don't pinch the dropouts to the point that they touch.

    From the description, it sounds like he didn't pull the axle down tight enough.


    OP: Do this
    1. flip the bike upside down
    2. loosen everything (4 pinch bolts, and the axle itself)
    3. wiggle the wheel back and forth (you should feel movement)
    4. tighten the axle down to the point at which all movement stops.
    5. tighten down a tiny tiny more (just...because you might as well)
    6. torque down the 4 pinch bolts to 19 ish in-lb,

    Done

    This doesn't sound like your 40 axle is loose. It sounds like the hub itself is loose.

    I read somewhere to not tighten the bolts to the point where the dropouts are completely pinched together.

    There's no play in my front wheel with the pinch bolts all the way loose... my guess is something else is going on. Hub play doesn't seem like the problem as the OP stated he can wrench those pinch bolts down past 19in/lbs and this fixes the play. My guess is your not putting the axle on tight enough.
    FWIW, I just snug those pinch bolts on with the small side of an allen, and don't wrench down on them at all.
    I'd rather have a bottle in front of me than a frontal lobotomy.

    Tightening the pinch bolts isn't going to stop any play in the hub.




    Sounds like your axle isn't seating properly in the lowers, and needs extra torque to get it clamped properly. I'm guessing tolerances are a little off on the axle, the lowers, or both.
