A dollop of PB blaster, then to the TV for Muscle Car(love that Lou) and a beer, then back out the the garage and the little turkey would have come off with just a little elbow grease.
It may be counter intuitive, but an impact gun might have worked as well. The jolts my have broken up the rust and corrosion. I use my new favorite tool(18v 1/2" cordless impact) anywhere it will fit.
In AZ the only time I see bolts that will do that are related to exhaust. I found the PB blaster plus 1/2 hour TV trick works well as I am not a patient man--some sort of distraction is the key.
I know it is a little late for this time, but next time around. :
Impact wrenches are invaluable when working on suspension and exhaust systems. For those of us who can't justify or afford an impact wrench, the penetrating oil trick works wonders. Placing a sacrifical nut on the fastener and rapidly striking it what a hammer can often work too. The vibrations from the imacts allows the penetrating oil to migrate into the microscopic nooks and crannies where corrosion resides. Care must be taken however to avoid damaging the threads the sacrificial nut is fastened to. Waiting a while and repeating the process usually loosens the most stubborn of fasteners. If that fails, the old heat trick usually does it. Unfortunately, putting a torch near paintwork or rubber bushings/o-rings/grommets, etc is a last resort.
Another trick is to use what is called a "nut-splitter". I wouldn't be without one. And yet one more trick is to drill a hole in the center of the offending bolt all the way through. This doesn't always work, but sometimes is effective, especially if the bolt is actually a stud in a blind hole.
When facing a stuck fastener, I try to remember that admonition to "work smarter, not harder".
