WJB WS710959 Differential Pinion Seal

The WJB WS710959 is a precision-engineered differential pinion seal designed to prevent lubricant leakage from the differential housing where the pinion shaft enters. This critical seal maintains proper gear oil levels and protects internal differential components from contamination and premature wear.

Key Features:

• Precision-molded design ensures proper fit and sealing performance
• High-quality elastomer construction resists heat, oil, and wear
• Metal case provides structural integrity and dimensional stability
• Prevents differential fluid leakage and contamination
• Direct replacement for worn or damaged original seals

Differential pinion seals are essential maintenance components that should be replaced whenever the pinion shaft is removed or when leakage is detected. A failing pinion seal can lead to low differential fluid levels, resulting in costly gear damage and potential differential failure.
