Years ago I had a Suzuki stuck so bad that I broke grade 8 puller bolts on it. It was warranty work so I called the rep and asked him if he wanted to stop by cause I was gonna get mean with it. He did come by and we broke a second set of bolts on it. The torch came out and it took an 8 lb maul hitting it so hard I was sure we were going to do internal damage. I had to buy a new puller, destroyed it with the toughest impact we had at the shop. They can be frustrating at times.
