Best way to remove these??

[72Charger-SE]

I am rebuilding the entire front end suspension and steering.  I am stuck trying to remove the knuckle arm from the wheel 'hub'?  I don't think I am using the correct terminology so here is a photo...  I have a new knuckle arm and can't get the old ones off??  PB6 has been applied as well as heat and they haven't moved a mm??

The single vertical stud is the lower ball joint (part of the steering arm); is that what you're trying to remove or the two bolts that hold the knuckle to the steering arm?

For the ball joint stud, support the lower control arm on a jackstand, thread a sacrificial nut onto the stud and use a BFH to drive it out; if you have an air hammer that works better. If you remove the knuckle from the steering arm you can "squeeze" the ball joint stud out by applying a hammer blow to one side of the control arm and backing it up with a heavy bar on the opposite side.

If it's the two bolts holding the knuckle to the steering arms will they turn?

Sorry.. bad photo...   I want to remove the two bolts holding the knuckle to steering arm...  I may end up cutting them as they won't budge...

Remove the rotor. The heads of those bolts are accessible thru the other side.
