Installation Notes and Tips

Verify rear-position fitment, compressed length, and bolt-on end configuration before installation. Confirm the vehicle application against the listed Mercedes-Benz S350 and 300SD model years, and inspect surrounding driveline components for wear before installing the new assembly. Because this shaft is not adjustable and does not use a slip yoke, correct application matching is important for proper installation.
