    #$%*& Squeek!

    Help!

    I've got a high-pitched squeek coming from my rear freewheel. It's intermittant, and seems to come only when I'm in one particular gear. Then it goes away for a bit until I forget about it.

    I can not replicate this on the stand! I have tried everything I can think of to replicate the problem with no success. If I can't replicate it, I can't localize it, and if I can't localize it, I can't fix it!

    I suppose it could be coming from the deraileur, but see paragraph #2.

    I have tried regreasing everything, but it keeps coming back. I am loath to tear down the drivetrain (and rear wheel) without knowing what I'm looking for. Any ideas would be greatly appreciated.

    On the other hand, I keep telling myself that it's now October, and so I'll be packing the thing up for a major annual pretty soon, so I just shouldn't worry about it until next year. But still it's making me crazy! And embarassed!

    Every rear wheel squeak I've ever tracked down was in the derailleur pulleys.
    Today, I believe my jurisdiction ends here...

    I agree. The deraileur pulleys need regreased.

    I actually did that as best I could w/o dis-assembling the deraileur (that can wait for the annual), but didn't help at all.

    Or, at least it didn't seem to - it is intermitant. Squeeks just long enough to make me insane, then stops for 2 or so days.

    The only way to properly grease the pulleys is to remove them from the cage, clean and regrease the bushing. It's a 15 minute job. Dumping oil around the pivots doesn't work because sides of the pulleys are grooved and trap the oil before it gets to the bearing.

    No reason to wait for your 'annual'. Those pulleys obviously need lubricated more than once a year anyway.
