my passenger side front window regulator finally went bad yesterday. it went down, but wouldnt go back up. it was making funny noises for some time, but didnt think anything of it. i took it all apart, and found the cap on the gearbox attached to the motor(regulator?) was popped off, and the black rubber gear/bushing was broken.
the black bushing/gear is molded to a steel shaft with the gear on it, well the bushing seperated/tore off the shaft, so there was still plenty of rubber attached to the steel shaft.
i have CA Glue for my rc cars tires. its made to bond plastic to rubber, or rubber to rubber, and it VERY strong, and bonds instantly. the rubber will literally rip apart in a different spot before it will come apart where it was glued, it pretty much bonds the two rubber pieces as one piece. you can get it at any RC hobby shop.
so i cleaned the two pieces of rubber real well with rubbing alcohol to get the gearbox grease off, and glued them together, held in place for about 15 seconds, and its fixed, not coming apart again. very strong. possibly temporary fix, but im sure it will last to be a permanent fix, i dont see it coming apart again.
