Leaf spring bolt welded on? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Now I'm no stranger to leaf springs, they suck to work with. I had to cut a bolt out of one of the brackets, naturally it had to be the front one, the worst one to deal with. I cut right in between the bushing and the bracket so the leafs just dropped out. Got the head of the bolt out with a mini sledge, penetration grease and a punch. The side with the nut on it however. Is a ****nami tidal wave of disaster. I can not for the life of me get it off. I don't have a air hammer so I'm working in the Stone age. I've used half a can of penetration grease, half a propane torch, and all the elbow grease my body can pump out and I can't get this thing out.

Any tips on how I might go about getting this out?

I would try more heat. Mapp gas (accedeline) is hotter than propane.
Or even better accedline and oxygen. I'm sure you know but if not heat the portion that the bolt goes into to expand that.

Just a little heat is not enough, heat it until it is red hot all the way through!
Then hammer the crap out of it.
