Detailed Description

The Cardone Air Suspension Strut line focuses on direct-fit replacement parts that are developed from application-specific engineering and testing. Part number 4J-1000S is built for front suspension service on the Ford Expedition and Lincoln Navigator, with fitment covering 2003-2004 Ford Expedition front left and front right, plus 2005-2006 Lincoln Navigator front left and front right. This makes 4J-1000S a practical choice when replacing a worn air strut on vehicles that rely on air suspension for ride height and comfort.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Uneven front ride height on air suspension-equipped Ford Expedition or Lincoln Navigator models
• Excessive bouncing or reduced damping at the front suspension
• Air strut leakage caused by worn seals or aging components
• Noisy or unstable front-end ride quality
• Loss of original suspension response after component wear

Installation Notes and Tips

Compatible With 2003-2004 Ford Expedition, front left and front right, and 2005-2006 Lincoln Navigator, front left and front right. Verify the upper stud mount, lower eyelet mount, and solenoid connection design before installation. Because this is a direct-fit air suspension strut, no modification should be required when the vehicle application matches the listed fitment.

Quality Assurance

Cardone designs and tests this air suspension strut to meet original equipment performance standards. The unit is individually developed for each application and includes new internal service components and protective canister hardware to support consistent operation in normal suspension service.
