I used Goop, and I have heard that JB Weld works good too. Make sure the surface is sanitary. I took the window off to work on it. To remove it you have to remove the roll pin at the last pivot on the latch. Open the window as far as you can then use a thin screw driver under the hinge pins (pin in your case) and tap out (up) with a light hammer. I used masking tape to mark the area where the hinge sat before it came off, clean the area inside the tape, and use the tape as a guide to place the hinge. Installation starts with the hinges, and then the roll pin.
