What It Helps Address

• Clicking or popping during turns from worn CV joints
• Vibration or shudder under acceleration from axle wear
• ABS-related drivability issues tied to a damaged tone ring
• Grease leakage or torn axle boot conditions that affect joint life
• Front-right driveline noise on Mercedes-Benz S430 and S500 models

Installation Notes and Tips

Verify the vehicle’s chassis number, side, spline count, and axle nut thread size before installation. Confirm the ABS tone ring tooth count matches the original setup and inspect the hub, seals, and mating components for wear before fitting the new axle. For Mercedes-Benz S430 front right and Mercedes-Benz S500 front right applications, matching the exact chassis breakpoints is important for correct installation.
