Detailed Description

SKF has a long history in seal engineering, and the 18190 differential pinion seal reflects that focus on material selection and dimensional accuracy. This seal is made to specific application requirements using premium materials to help maintain proper sealing at the pinion area, where gear oil retention and contamination control are critical. It is a practical replacement choice for Ford Expedition front differential service, Ford F-150 front axle repairs, Lincoln Navigator front differential work, and other listed applications. The SKF 18190 is also used in select Mazda rear differential applications, including B2300, B3000, B4000, B2500, and Navajo models.

Fits 1997-2017 Ford Expedition, front. Fits 2004-2017 Ford F-150, front. Fits 1998-2017 Lincoln Navigator, front. Fits 2001-2010 Mazda B2300, rear. Fits 1994-2010 Mazda B4000, rear. Fits 1994-2008 Mazda B3000, rear. Fits 1998-2001 Mazda B2500, rear. Fits 1991-1994 Mazda Navajo, rear. Fits 2006-2008 Lincoln Mark LT, front.

Common Repair Uses

  • Stops differential gear oil seepage at the pinion area
  • Addresses contamination entering the differential housing
  • Replaces a worn or hardened seal during axle service
  • Helps correct leaks found during driveline inspection
  • Supports repair of noise or fluid-loss concerns tied to seal wear

Installation Notes and Tips

Inspect the pinion yoke, shaft surface, and surrounding housing before installation. A worn groove, corrosion, or scoring on the sealing surface can shorten seal life, so the mating surface should be clean and smooth before the new seal is installed. Confirm the seal dimensions and vehicle application before assembly, and verify proper differential fluid level after service.

Quality Assurance

SKF designs and manufactures seals to high quality standards, using application-specific materials and bonding methods developed from decades of seal engineering. The 18190 is built for long service life in driveline environments where consistent sealing performance matters.
