Help with removing the uca bolts!

I fought one bolt on each side for hours, my arm felt like rubber from hitting it back and forth with a hammer. Here's what you do. After soaking with penetrant, hit it with an air chisel fit with a blunt tip. Both came out in a couple of minutes!!! I still had to go back and forth a couple of times, and kept spraying them with penetrant. I had the air chisel, but had to borrow the blunt tip bit. I brought that guy a 12 pack when I returned it!!!

Oh yeah, and wear eye AND ear protection. An air chisel working in a wheel well will make you deaf!!!
