Keep gear oil sealed inside the rear differential and dirt and water out with the SKF Differential Pinion Seal 19802. It drops in as a direct-fit replacement for the 2007-2021 Toyota Tundra [All], sealing the pinion shaft where the driveshaft meets the rear differential. The seal body stays stationary while its lip rides against the rotating pinion shaft to hold lubricant in and contaminants out.
- Garter spring: cold-drawn steel wire for reliable fluid retention.
- Rigid metal case: deep-drawn sheet steel forms a stress-resistant body.
- Polyacrylate sealing surface: the sealing lip material listed for this seal.
- Contaminant protection: helps guard against dirt and water intrusion.
Built to specific SKF designs with tested materials for correct fit. Key dimensions: 2.060 in inside diameter, 3.440 in outside diameter, 2.047 in shaft diameter, and 0.402 in width. If a worn or leaking pinion seal is the source of gear oil seepage at the rear differential, this replaces it. Country of origin: Taiwan.
