the gear housing doesn't have screws, they have pins. The screws are there for the wiper arms, which attach to the gears. the grease they pack the gears with it made its way to those pins on mine, which allowed the case to open up when the gears were under load, causing the gears to skip and grind on the worm gear from the motor. I threaded the holes for the pins, and replaced them with machine screws. Problem was solved. Its a strange design IMO. I wonder how many of the wiper motors have failed because of this reason when there is such an easy fix.
