Then you need a way to get physically around the item (while it is still mounted, broken) to accurately measure it. Then you need a means to re-install it, repaired, after removing the old one. The fundamental truth is that it's significantly cheaper (and lighter, and uses less material) to design throw-away products at this level than to engineer removable elements to make them possible to repair.
