  Differential Pinion Seal, Seal

• Description:

  This is a genuine Ford Front Pinion Seal, part number 2L1Z-3N134-AA. It is a differential pinion shaft seal that rides against the rotating pinion to keep gear oil inside the axle while blocking road grit and moisture. A fresh seal restores the factory oil barrier and protects the ring-and-pinion from contamination and lubricant loss. This part applies to F-150/F-150 Heritage/Expedition + Lincoln Mark LT/Navigator (front differential pinion seal), covering the 2003 to 2008 model years where the original equipment part was used; always confirm fitment against your specific year, model, and engine before ordering. As a genuine Ford part it is built to the original engineering specification and held to factory quality control, so it fits and performs like the component it replaces without the guesswork of aftermarket substitutes. This is a single-use component and should be replaced with a new part whenever the joint or connection it serves is disturbed, since reusing it can compromise sealing or clamp load and lead to leaks or loosening over time. Installing the correct Ford part number the first time avoids return trips and the fit and reliability problems that come with incorrect or lower-grade replacements, and it keeps the vehicle's systems working the way the factory intended. Order by part number 2L1Z-3N134-AA to be sure you receive this exact genuine Ford component.
