Installation Notes and Tips
Verify rear fitment by year, model, and driveline configuration before installation. Confirm the 62.125-inch compressed length, bolt-on end style, and shaft diameter match the original unit. Inspect companion flange surfaces, mounting points, and surrounding driveline components for wear before installing the replacement shaft. Because this assembly is pre-balanced, avoid altering the shaft or adding unapproved modifications after installation.
