I've managed to get the ball joint from the hub despite the thread spinning with the nut, grr! But now i can't shift the rod from the bar. I'm using a 21mm spanner on the rod and 13mm spanner on the bar...i could do with more leverage and will try and think of something. I'm spraying wd40 but in truth there's nowhere for it to get into, and i'm heating the rod end with a blow torch. I got fed up and come indoors but if anyone's got a magical piece of info...or a wand i can borrow and i'll try again another time!?
