So I have everything removed with except of the "knuckle" that joins the rack and pinion to the steering wheel shaft. I removed the bolt between knuckle and rack n pinion and also removed the bolt between shaft and knuckle. parts do seem a little rusty so sprayed WD40 on it for now, but i cant get them loose to be able to remove the rack and pinion out. Any suggestions or special tools to use for this 2009 G37x AWD coupe rack and pinion removal?

Thank you!
