After bending the regulator back you can see that it's much straighter and that the gear now can move freely without rubbing. You can compare it to the original state of the regulator in the third picture.

Before re-installing the regulator grease the gears thoroughly with an extreme duty grease like moly wheel bearing grease or SuperLube silicone grease.

After bending and lubricating the regulator on this car was re-installed in the door. The window moves up and down somewhat more quickly, and without any rattling or clunking, but it still moves much more slowly than desired. It is likely that this motor has been damaged by the window being used despite the bent regulator.

In a future guide the motor will be replaced with a good used motor.
