Well, this happened today. A few years ago (2017) my truck was involved in a hit and run where the offender totaled my truck. This included the rear driver side fender flares, front driver door and front fender and fender flares. So I gathered the needed parts and got it fixed by an independent business/person. While they did a good job of painting the newly gathered parts, it seems as though when they reattached the rear driver door flare, they didn't install it the way it came from the factory. So today it just ripped right off without any warning or signs of weakness. Pretty bummed about that. Now begins the process of fixing those small rust spots on the door and then reattaching the flare to the door.
