Hi,
I have just tried to remove the main nut on the rear hub, so that I can replace the rear wheel bearing. The nut undid slightly (to the extent that there is a 0.5mm gap between the rear of the nut, and the washer). However, the nut will not come back any further. It will turn (both clockwise and counter-clockwise), but is not moving either up or down the thread on the hub bolt/pin. The bolt/pin is not spinning.
I have never had this problem before, but I need to remove the nut. Any suggestions as to how I should proceed would be really appreciated.
Thank you,
