- Description:
This genuine Ford vacuum tube is the lower 4WD vacuum line that feeds the front-hub Integrated Wheel End (IWE) system on the 2010-2017 Ford Expedition and Lincoln Navigator with four-wheel drive. Ford catalogs it as a Tube - Vacuum. On these trucks the front hubs are engaged and released by vacuum-actuated IWE units, and this molded line routes engine vacuum to the front-axle actuators so the hubs lock in when four-wheel drive is commanded and free-wheel in two-wheel drive to save fuel and reduce wear. Because the line runs near the engine and front suspension, it hardens, cracks, chafes, or loses its connectors with age and heat, and a leaking vacuum line is a common cause of IWE trouble. Symptoms of a failed line include a loud grinding or crunching from the front hubs on acceleration, four-wheel drive that fails to fully engage, or a hissing vacuum leak. Replacing the cracked line with this correct factory vacuum tube restores proper vacuum delivery so the front hubs lock and release as designed. Confirm the routing and connector fittings for your Expedition or Navigator against this part before installation, and inspect the check valve and actuators while the system is open.
