rear hub nut on a saff.. 41 mm nut . the rear arms are off the car i no i should have tried whilst still on the car. i used a thick extension bar through one of the holes in the hub to lock it which started to bend then snapped a 1/2 inch ratchet and it didnt budge at all.. tried heating it up but still no good.. any ideas or is it a job for a machine shop...????? cheers
