VW Golf MK1 vent window pivot bearing

thingiverse

The pivot bearing is responsible for rotating the ventilated window in the Volkswagen Golf MK1. It allows the glass to move up and down while still providing protection from wind, dust, and other external elements. Typically found in vehicles manufactured before a specific year or redesign, this component requires precise lubrication to operate smoothly. The manufacturer recommends applying specialized grease every few months to ensure long-term reliability. Worn-out pivot bearings can cause the window to become stuck or develop loud noises during operation, necessitating replacement by a qualified mechanic.
