    Rear Hub issue......is my skewer bent?

    I have been hearing a sound ever since I got this bike and I could never pinpoint what it was. I think I may have it figured out. When I spin my back tire there is the normal clicking sound from the cassette. but if you listen closely there is also a click sound every revolution. You can really hear it as the wheel slows down. When I sight down the drive train while the wheel is spinning, there is a slight wobble in my cassette consistent with this clicking sound. Just my preliminary diagnosis, but does my skewer have a bend in it?
    It seems to me that it could be causing the sound/wobble?

    I shot a video. You really can't see the wobble very well....maybe a little toward the end if you really focus on it. But you can hear the clicking very well.

    A bent skewer would not make a noise because the axle surrounding it does not turn. Besides, a slight bend in the skewer would be pulled straight under the tension of the closure.

    Hmmmmm. So could it be that my cassette is not flush against the hub? Or it is just a little loose? The clicking is what bugs me. Obviously something is catching in there. Possibly a stuck bearing or something?
    Bummer is I don't think I have the necessary tools to remove the cassette.

    Most freewheels have a little wobble. Does the tick happen when you are pedaling? You can also drip some chain lube in the freewheel to see if the click goes away. I couldn't hear anything out of the ordinary.

    +1 on what curbtender said about some wobble being common and evident when the wheel is spun backwards as you were doing. That wobble should not be evident when peddling forward as you normally do when riding since the pawls inside the freewheel/freehub engage the hub in a solid manner in order to propel the wheel. Likely the best you can do is to flush and reoil it which has been covered many times. Else try new hub. Also +1 on supcom's comment. Right on!
    P.S. to some freewheel noise is a sign of quality since some of the most expensive hubs are the noisyest.

    Actually in that video I was pedaling forward.
    Thanks for input. I'll just try to give it some lubrication. I guess I'm just being a bit OCD.

    The tick was just bugging me. You know when you hear a noise but you can;t figure out what it is? I can't let questions rest until I solve them.
    I'm OCD....I guess that's just proof of it.
