Hi all, i am new to the scene of mechanic on a bike i have just taken off my rear wheel which is quick release and have taken out the quick release and re greased as well as backed of the not holding the gears on so i could get a twig out, reassembled all tightened the nut for the gears and when i but it back on everything lines up, but the nut on the side opposite to the gears is rubbing up against the frame and is shaving off metal when quick release is still loose and with it tight there is no movement at all. Not sure if this matters but i took apart the rear disk brake assembly cleaned off brake dust with air and put back on.

Thanks in advance
