- Description:
Genuine Ford OEM front axle and intermediate shaft sealing ring for 20-25 Lincoln Aviator and 21-25 Ford Explorer AWD applications. This sealing ring serves as the front axle vacuum disconnect interface seal, isolating the right-hand intermediate shaft from the front axle housing during transitions between two-wheel and all-wheel drive operation. Ford supersession history: this part replaces L1MZ-4A015-A, L1MZ-9F598-A, and N1MZ-9F598-B in the dealer catalog. The component is referenced in Ford TSB 23-2174, which addresses an AWD wrench warning light combined with stored DTCs C00A6 and C0631 on Aviator and Explorer vehicles built on or before August 30, 2021. Service requires complete replacement of the sealing ring as a sealed assembly with the front intermediate shaft. This part cannot be reused once removed and is considered a single-use sealing component during axle service. Always lubricate the new sealing ring lightly with axle-rated assembly grease before installation. The replacement is critical for restoring proper PTU disconnect operation and eliminating false fault codes after AWD service. Backed by Ford Motor Company quality control and the standard Ford OEM parts limited warranty when installed by an authorized dealer. Verify build date and VIN against TSB 23-2174 to determine if your vehicle is included in the affected production range before installing.
