Glad it worked for you...sometimes the BFH and torches aren't always needed!.
My friend was beating a leaf spring bolt with a sledge hammer one day when I stopped at his shop,and he said he'd been at it a good half hour,all he accomplished was mushrooming the bolt ,and he had to keep grinding it off so if it did come free,it could still go thru the bushing...it was evident it wasn't going to budge,and we couldn't use a torch because the gas tank was right behind the spring bolt and it was plastic..
...he didn't want to saw it off either,because then he'd have to get a new bushing somewhere,most likely not the same day too,and tie up his lift..
I told him about the nut & washers trick I'd used,we tried it but the threads stripped on the bolt when we put the air impact to it..he was just about to saw the bolt off when I saw his ball joint press tool sitting on the workbench...I asked if he'd tried that already,he said "no,I used it earlier to do lower ball joints on a Durango...
I suggested he try it,he was skeptical,but was ready to try anything once..it took both of us to thread the tool in there, and hold a socket on the back side till we got it clamped,then one BLAAATT from the air gun,and the bolt popped and pushed right thru,slick as snot..
He looks at me and says "where were you an HOUR ago!"...
I've seen air hammers that spring shops use,they dont screw around--they look like half sized jackhammers like they use to chisel up asphalt or concrete in road repair!..one guy told me if your not careful,you can vibrate a vehicle right off the lift it you leave it on too long..usually the bolts come right out with those tools...torches cant be used as often as they used to be,with more trucks having plastic gas tanks and nylon fuel lines..
