Howdy Gentlemen,

I can not seem to get the castle nut off of my passenger control arm, it seems to be seized pretty bad!

I've tried a 24" breaker bar, PB Blaster, extended it 2 more feet with a cheater bar. Took a propane torch to it and rented an 18v Makita impact from home depot, that didn't budge it. At this point, I'm not sure if I should cut it off. Am I at risk of hurting other things if I wail on it more?

The tie rod and sway bar are off, but the caliper is still on. I'm replacing the LCA and UCA ball joints entirely and had only planned to reuse the steering knuckle, maybe there is a better way?

Which castle nut do you speak of?

If its the one on the upper ball joint you have to hit it with penetrant and follow with an impact gun. Same for the one on the lower ball joint. Besure the cotter pins are out too.

Lower! Cotter is out. I tried a nut splitter, but it angled and didn't go all the way through. Decided to get a dremel to finish it off.
