It sits near the center support carrier bearing and connects the driveshaft to the universal joint, transferring engine torque to the rear axles. The 46-spline hub can wear from road vibration, lack of grease, or high mileage, leading to driveline vibration or failure. Replacement is needed when the splines become loose, elongated, or damaged.
