Got it done
Thanks for the help everyone
. Borrowed a lump hammer and let my frustration out on the hub, it split in 2 but I kept going and it eventually came unstuck.
On the basis that you won't need the hub nor the 4 M12 spline bolts, leave the 4 M12 spline bolts in by about 6 threads and hit each one in turn hard with a big hammer from behind. Don't be tempted to get a screwdriver or anything else "flat" between the bearing and the hub on the front face and start wrestling with it.
You may need to sacrifice your M12 socket cheaper than taking it to the Indy.
Wish I'd thought of this when I first attempted the job, will remember that when I'm doing the other side
