took the windshield out today. It was pretty simple, just requires patience!
Windshield knife. It is possible to use a simple utility knife, but the windshield knife make it much easier to cut the rubber seal because you could use both hands! I bought the K-tool international knife (KTI70545).
Windshield removal tool. Item # 117357 on Northern tool's website. This is used to cut the caulking around the windshield. ONLY USE THIS TOOL IF YOU ARE NOT PLANNING TO USE THAT WINDSHIELD AGAIN!!! this tool will very likely crack the glass. I was removing the glass to repair some rust that was starting under it and get it ready for paint, so i used a small steel cable to cut the caulking instead.
pull the inner rubber seal out that is around the frame. should come out by hand.
Take the knife and cut the outside rubber seal all the way around. I am getting my YJ ready for paint so i put the knife behind the rubber on the frame side because i did not care about scratches on the paint. after it is cut, pull the seal out. if the glass is scrap, i would cut on the glass side. in other words the knife's blade would be between the rubber seal and the glass.
If you are not reusing the glass, take the removal tool and work it through the caulking, than use the handle to pull it towards you (AGAIN, THIS IS VERY LIKELY TO CRACK THE GLASS). i would recommend doing half the windshield at a time. meaning, start in the middle on the top and go to one side, then cut the side, then the bottom from the middle to that same side. you might have to do this twice on each cut. once you go all the way around, the glass should just come out!
If you are reusing the glass, take a steel wire and work it through the caulking so that one side of the wire is on the inside and the other on the outside. Use 2 vice grips to work the wire back and fourth, it will work like a saw and will cut through the caulking without cracking the glass. this will take a longer time than the removal tool, so you have to be patient!
