Propeller shaft hangers are vehicle-specific mounting components securing the driveshaft to the underbody, typically found on rear-wheel-drive and four-wheel-drive vehicles. These hangers utilize rubber bushings to dampen vibration and isolate noise while allowing for necessary driveshaft articulation. Construction varies from pressed steel to polyurethane, depending on vehicle application and performance requirements. Precise positioning is critical to maintain driveshaft alignment and prevent premature wear or vibration. Variations include single-hanger and multi-hanger designs, often incorporating a crossmember for added stability.
