    I reckon you mean the freewheel?
    If so, you don't normally need to remove it to replace an axle (assuming cup-and-cone bearings, which any wheel old enough to take a freewheel (as opposed to a freehub cassette) will probably have).

    Start again from the beginning, though - what are you actually trying to accomplish and why?
  • my back wheel on my bikes buckled and save buying a new wheel i thought i would change the axle

    That will fix a bent axle but not a buckled wheel which is the rim not being straight to the hub.

    What is shighting and axles shouldn't rub on frames.

  • i mean strighting and its my wheel what rubbing
  • cooldadcooldad Posts: 32,599
    So what is strighting? Do you mean straightening? If so what was he straightening? Presumably if something is still rubbing whatever wasn't very successful.

    If the tyre is rubbing on the frame just at some point/s in the wheel's rotation, then this is because the rim is buckled and the wheel needs "truing" (straightening) by adjusting the spoke tension (or possibly rebuilding the wheel with a new rim if it's damaged beyond repair).

    If the axle is bent, then the tyre will probably be shifted toward one side of the frame, and will rub (or nearly rub) at all points around the rotation.
  • it was the axle he done and it the tyre whats rubbing

    So was it rubbing through the whole rotation, in which case bent axle and a new axle is the right fix, in which case the wheel wasn't buckled at all.

    If your English isn't good then maybe posting some pictures would help?

    What has he done to the axle, and why didn't he just fix it?

    Agreed, please try and take a little more time with your typing, it's very difficult to understand what you're trying to explain.
