All- thought I would post this up here as it might help someone with similar problem, chewed up and seized front bearing retainer - this is how it started -

So after drilling out the staking - used a dremel and drill on the inside edge of the retainer to try and break it free, then used a punch to collapse it on itself and 'peel' it out of the hub

You can normally just break it with a cold chisel due to it being alloy. A Dremel risks the chance of thread damage IF you go a bit deep or it veers off target. Drive the chisel in off the edge and towards the bearing and it normally breaks where the slots are for the special tool.

I managed to extract- combination of very careful dremel/drill/ punch to fold it in on itself - there is evidence of damage to the threads in the hub from previous drilling of stakes, but overall the threads cleaned up quite well with a thread file
