Steering All Over the Place at 55mph+

I was going the correct way. I flipped the tool to the other side of the control arm. Inside of the arm towards the outside.

As you can see in these pics the damn things are just seized in there.

Y'all have been giving great advice BUT since I'm replacing the UCA's now, if I buy tubular ones do I need the offset bushings in them as well? Any recommendations?

If you or someone you know is handy with a torch you could slice those bushings out. put the torch head at angle that is almost parallel with the bushing and hit the O2 as soon as it will cut. once you have a slice in it you can drive the sidewall of the bushing toward the center with a hammer and punch or chisel.
If you have access to an air chisel you could try collapsing the bushing into itself.
You could also use a die grinder to thin the shell where it passes through the A-frame and collapse the bushing with a hammer and chisel where you thinned it.
You could use a hacksaw or sawsall to slice the bushing.
You don’t need to save the shell so don't be afraid to get after it. Just be careful not to hurt the A-frame. What have you got to lose?
