WJB WS711091 Differential Pinion Seal

The WJB WS711091 is a replacement differential pinion seal designed to prevent fluid leaks at the differential pinion shaft. This seal keeps gear oil contained within the differential housing while blocking road contaminants, moisture, and debris from entering — protecting internal differential components and extending service life.

Key Features:

• Precision-machined rubber sealing lip for a consistent, leak-proof fit around the pinion shaft
• Multiple external ridges provide a secure press-fit retention within the differential housing bore
• Engineered for reliable performance across a wide range of operating temperatures and fluid environments
• Manufactured using all-new components — no remanufactured or reconditioned parts
• Direct OEM-style replacement for straightforward installation

The WJB WS711091 differential pinion seal is a quality aftermarket solution for restoring a proper fluid barrier at the differential. It is well-suited for both routine maintenance and leak repair applications.
