Help keep gear lubricant inside the rear differential and road grime out with the SKF differential pinion seal, part number 17336A. It fits many vehicles as a direct-fit replacement on the rear differential, among them the 1995-2015 Toyota Tacoma, 2000-2006 Toyota Tundra and 2001-2007 Toyota Sequoia. See the "Vehicles it fits" section for the full list and engine-level details.
The pinion seal sits in the rear differential housing where the pinion shaft exits toward the driveshaft. The seal body stays stationary while its sealing lip contacts the rotating pinion assembly. This helps hold lubricant in and keep contaminants out.
- Rigid metal case: The body is formed from deep-drawn sheet steel, creating a stiff, stress-resistant metal case.
- Steel garter spring: The garter spring is made from cold-drawn steel wire. It helps keep the sealing lip in contact for fluid retention.
- Tested for correct fit: The seal is made with a tested design and quality materials intended for a correct fit.
- Contamination protection: It is designed to guard against dirt and water intrusion.
SKF introduced the first integrated shaft seal in 1928. Since then, the company has continued to develop new seal designs and bonding techniques. Its seals are built to specific designs, with materials selected to suit both the application and its operating environment.
Signs this seal may need replacing include:
- Gear oil seeping from the front of the rear differential
- Oily residue around the pinion area
- A low differential fluid level
If a worn pinion seal is the source of the leak, this part replaces it. Diagnose the leak before replacing parts.
