I found a little trick to help remove those annoying upper rear shock bolts. Use an impact wrench at about 60 - 80 psi. I did the PB blaster on all of them like I have read in so many treads, but I still broke the first bolt by hand. I decide that if they were all going to break I might as well make quick work of it and pulled out the impact. To my surprise the next three came out without breaking. They still came out hard, but they did not break. I wish I had known this before I snapped the first one, I spent all morning drilling the busted bolt out.
