Posted earlier that I will look even at aftermarket solid rear windows.Is it ever an option to go with a non slider rear window if the slider window frame cracks? These frames are cracking because manufacture defect right? Poor choice of plastic blend. Is there a particular area of the USA these crack more often? Isn't replacing the window frame with another made from the same exact materials means the replacement will crack eventually too. I doubt these chassis and bodies are flexing to cause this issue. Urethane window sealant isnt failing on these. That's a proven material made by 3M. The plastic frame is failing. In all these threads are there pictures of these frames outside of the vehicle prior to installation? I can never find a picture online. Are there any techs on here?
