Windshield Wiper Linkages synchronize movement between the two wiper blades on a vehicle. If a linkage is broken, the affected blade stops working. CARDONE 100% New Windshield Wiper Linkages provide a high-quality, convenient solution to this problem. They were designed as a more practical solution than changing the plastic bushings, which can be a time consuming and difficult process. CARDONE linkages are complete units that match O.E. performance at a fraction of the cost.
