Dremel or center punch and drill with a good bit. Drill the bolt out by center punching the center of bolt then drilling till you hit unwelded metal.

I just went through this with my trailer.

You have an impact gun? I picked up an electric 1/2" from harbor freights for like $50, (worth it's weight in GOLD for this project) I was able to remove my nuts like normal, with the impact gun, then I sprayed it down with pb blaster, then, and here's the key....

put the impact gun on the bolt head (with no nut on the other side) and spin the crap out of it, forward, backward...etc. When it starts smoking, stop and spray it down with pblaster again. Then spin it some more. While it's still smoking hot beat the shit out of it with a heavy hammer, while swearing and cursing loudly at it (I used a splitting maul).

After that they came right out! :D

In most springs there is a nylon bushing, I'm thinking you've got to melt it a tad to get it to release from the bolt. At least that's my story!

Trust me, I pulled my hair out for an hr or so before I 'thought' of it. After I got the process down all 4 bolts were out within 20 mins.

You might have steel sleeves inside the rubber spring eye bushings.
And they are rusted to the bolt inside.
If you have an air chisel, run the chisel on the very end of the bolt to rattle the the rust bond loose.
Has worked for me on nylon bushing'ed spring bolts too.
