No amount of wellying at the disc will get these brutes off. But, 3 oak wedges approx 75mm long and tapering 30 to 40mmm will. Theres 3 places behind the disc where you can belt them in with a lump hammer. A small cold chisel belted in at the bottom aswell and the hub came free! Thats if your replacing the discs ofcourse as they will get damaged. Sounds a bit adhoc I know but it got the job done and saved buying the proper disc removal tool.
