Last I heard there are NO strut yokes in the parts system, the part that attaches to the bottom of the strut and straddles the driveshaft and the LCA bolt goes through. So if you damage that strut yoke you may have to wait 6 months to get a new one.
I live on the edge of the Salt Belt in Maryland, we get a week or two a year of snow here and they salt the roads. My LCA bolts were rusted in and could NOT be pounded out with a hammer, but I did get them out by doing this:
I put a wrench (21m or 22mm?) on the head of the LCA Bolt and turned it back and forth as far as it could go without damaging the anti-rotation tab on it. Then pounded on it with a sledge, and got it to move a 1/2", sprayed in some more PB blaster, then twisted it again back forth with a wrench, repeated the pounding, PB blaster and twisting with a wrench again, to move it out 1/2" at a time.
It took a lot of torque to turn the bolt at first, but it loosened up more and more as things progressed.
Twisting the bolt head with a wrench will break up the corrosion enough to free it up just enough to hammer it out 1/4"-1/2" at a time, the PB blaster will penetrate more and more.
When I put it back together, I slathered Anti-Seize all over the bolt to prevent it from seizing again.
Considering how much more mild my corrosion conditions are compared to some of the bigger salt states, this may NOT work for all Commanders/Grand Cherokees with rusted/seized LCA bolts. Some you may NOT be able to turn the LCA bolt head at all with a wrench, try a strong air impact hammer, try banging on one end of the bolt with a hammer while you use the air impact wrench to twist it, etc.
