OE-Style Fit and Material Control

Delphi TD4819W is engineered for rear sway bar service where the original bushing has worn, cracked, or lost its ability to hold the stabilizer bar securely. Delphi applies dimensional and material analysis to match OE requirements, and the part is tested for temperature extremes and salt spray exposure to support durability in demanding underbody conditions. This part cross-references Ford OE 7L1Z-5493-C for the same application.

Fits 2007-2017 Ford Expedition, rear with 19mm Diameter Sway Bar. Fits 2007-2017 Lincoln Navigator, rear with 19mm Diameter Sway Bar. Delphi TD4819W is a direct-fit rear stabilizer bar bushing kit for these vehicles when equipped with the specified sway bar diameter.

Common Repair Symptoms

• Rear suspension clunking or rattling over bumps
• Excessive sway bar movement at the rear axle
• Worn, split, or hardened stabilizer bar bushings
• Loose-feeling rear handling response
• Noise caused by bushing-to-bar wear

Installation Notes and Tips

Confirm the rear sway bar diameter before installation to ensure the 19 mm bushing size matches the vehicle. Inspect the stabilizer bar surface for wear or corrosion before fitting the new bushings, and replace any damaged related components as needed. Delphi TD4819W is listed for rear use on 2007-2017 Ford Expedition and 2007-2017 Lincoln Navigator applications with a 19 mm diameter sway bar.

Quality Assurance

Delphi uses OE-focused engineering and validation methods for its steering and suspension components, including dimensional checks and environmental testing such as temperature cycling and salt spray exposure. The result is a standard replacement bushing kit built to support consistent fitment and long-term service in rear suspension applications.
