Changing my lower control arms 31126760276 and sway bars, left side went like a dream, the right is not coming off !

Using a ball joint fork and a universal seperator which was too small.

WD40
Bashed it
Heated it
Bashed it

Q. How long do I have to heat the steering knuckle ?

Q. Any ideas who sells a ball joint remover big enough thats not the BMW OEM $300?

My 3hrs DIY weekend is totally f@cked and the wife needs to car next week.

Thanks,
