Not addressing the OP (already addressed) but I caved to one of those "new silent nylon wheels" ads on social media for the door... Prior to that I youtubed a video or 2 on maintenance and lubed everything - those hinges OP shows, the main spring, the cables, the motor track, etc. The results were *amazing* in terms of noise reduction. The new wheels (put on later) only added 10% to that. Lube those things !!!
