Common Problems This Part Can Address

• Clicking or popping from a worn rear axle joint
• Vibration during acceleration from a damaged axle shaft
• Boot cracking that allows grease loss and contamination
• Excessive driveline play at the rear left wheel end
• Noise caused by a failing CV joint assembly

Installation Notes and Tips

Verify rear left fitment by year, model, and axle configuration before installation. Confirm the axle nut thread size, spline count, and overall compressed length against the removed part. Inspect the hub, seals, and surrounding suspension components for wear before installing the new axle shaft.

Because this application uses a cotter pin locking axle nut, follow the vehicle service procedure for proper torque and locking method. If the vehicle is equipped differently than the listed application, compare the original axle to NI-8340 before assembly.
