Anybody got any good tips for getting one off that's bolted into a rear drum. Tried drilling my drill bits suck barely scratch the surface. Tried hammer it round with a screwdriver//chisel no joy. Have even got a locking wheel nut remover but it won't fit over the outside part off it. Bit of a nightmare as I have sold the wheels and really don't have time for taking it too get a nut welded on. So lets hear anyones story of how they got theres off?
