How to replace the wiper gear assembly

09.11.2022 /

Windshield wipers protect car windows from rain and debris. The wiper gearbox transfers power from the wiper motor to the wiper arms.

The wiper gear is a mechanical device that transmits power from the wiper motor to the wiper arms. The wiper gear assembly, usually made from forged steel components, is typically two or three sections, with some assemblies using four linkage sections to complete the system. The wiper gear assembly is designed in such a way that a linkage drives the wipers in full motion across the windshield during use.
