can anyone tell me what size socket I will need to remove the rear hub nut on my octy? It looks like a star type one and are they available at Halfords and such ? cheers Dave

If it's the same as the front, the nut will fit into a standard bi-hex socket. It' just looks like a special, but is a 12 point nut that will fit a the 12 points of a standard bi-hex socket. 32/33 from memory without going out to look.
