    Crazy Clunk sound

    Hi

    My bike has startet to make a crazy clunk sound from what sounds like the Crank. But it is only present when putting weight to the left pedal, and periodic, which lead me to think it is the freehub.

    But then again only left pedal/crank arm

    Here is a link to a video i madelast night.

    Has anyone experienced anything like that?

    The Bike is Diamant Mammut F3 2014 mod

    Did you pull your crank and check the bearing?

    No not yet, was about to do it yesterday but did not have the time.

    I checked the pedals, and removed left crank arm, greased it up. But that did not help. I will check the bearing today, but would the "clunk" not be present all the time if it is the bearing that is faulty?

    Loose pedal, loose crank arm, loose BB cup, loose chainring bolts, loose hub etc.

    No, not all the time, particularly with a BB cup, they typically sing only when loaded.....

    I did not mean all time as when not loaded, i was thinking about the periodic aspekt. I will have to turn the pedal to one specifik placement, as if it is related to the freehub.
