• Replacement needs after shaft damage or corrosion

Installation Notes and Tips

Verify rear application, length, and end types before installation on the Subaru Impreza. Inspect mating flanges, slip yoke engagement, and driveline angles during service to confirm proper alignment. Because the assembly is pre-balanced and pre-greased, it is ready for installation once the vehicle is prepared and the mounting points are clean.
