• Air leaks from aging seals, O-rings, or connector points
• Debris-related wear on exposed suspension components

Installation Notes and Tips

Use the detailed instruction manual and video resources during installation. Confirm the vehicle is a Mercedes-Benz W220 S-Class Sedan with AIRMATIC and without 4MATIC before ordering. Inspect the surrounding air lines, mounts, and related suspension components during replacement to avoid repeat service on the front axle. AS-2605 is pre-assembled to reduce build time compared with rebuilding a strut from separate parts.
