I see that this post was several years ago, but wanted to post for future reference. I had the same problem of the window making a loud rat-tat-tat at full up or full down; with a new regulator. As I suspected, it was the motor gear slipping in the regulator gear (jumping teeth). Gears had grease on them from the previously failed regulator. Cleaned with alcohol. Even applied some spray adhesive for good measure. Works fine now. Lesson learned; clean the gears thoroughly when replacing regulator!
