CV Axle Removal (urgent)

hey guys-

My left-frint CV axle has gotten to the point where the steering wheel will shake in my hands when i'm driving straight. last friday I put the car on jackstands in my garage at home and set to the task of pulling the axle so i could mail it off to be rebuilt. One stick nut is standing in my way.

In order to remove the axle, it is necessary to detach the hub from the suspension piece. There are two rather large bolts holding a sort of "A" piece together right below the spring. The bottom of those two bolts is stuck and the nut has begun to round off.

I've tried soaking the nut & bolt in WD-40 and PB Blaster, I've wailed on both of them with a BFH, and I've pulled on a breaker bar with all my strength. Before I left my house, I gave the nut and bolt a good soaking of PB Blaster in hopes that it would sit and penetrate over the weekend so that when I come back today, it'll be good to go. I also haven't tried torching the nut and will likely try today..

does anyone have any input?
