• Front-left corner sagging or uneven ride height
• Air spring leakage from a worn strut bladder
• Excessive bouncing or reduced damping control
• Suspension warning lights related to air pressure loss
• Ride quality changes caused by worn OE air strut components

Installation Notes and Tips

Install AS-2548 at the front left position only on the listed Mercedes-Benz models. Verify the vehicle’s suspension code, connector layout, and mounting style before installation. Because this is an air suspension strut, the system should be depressurized and the vehicle supported correctly before removal. After installation, perform a ride-height check and clear any suspension fault codes if required.

Quality Assurance

Arnott’s REMANUFACTURED suspension line is built around rebuilt OE components with updated wear items where specified. AS-2548 is backed by a Limited Lifetime Warranty.
