InMotion WS710871 Engine Crankshaft Seal - Rear

Rear Differential Pinion Seal

The InMotion WS710871 is a rear differential pinion seal built to maintain a tight barrier at the pinion area and help keep contaminants out of the differential. It is specified for a range of Toyota, Lexus, and Scion rear applications, including Toyota Tacoma, Toyota RAV4, and Lexus ES300h fitments.

Key Features

• Fluoro-elastomer construction for resistance to heat and fluid exposure.
• Precision dimensions for a secure seal at the housing bore and shaft interface.
• Helps reduce gear oil leakage from the differential pinion area.
• Fits rear differential applications across multiple Toyota, Lexus, and Scion models.
• Part number WS710871 for easy identification and ordering.

Detailed Description

WS710871 is engineered as a differential pinion seal for rear applications where a reliable sealing surface is critical. The fluoro-elastomer material is selected for durability in demanding driveline environments, while the listed inside diameter, outside diameter, and housing bore dimensions support proper sealing at the pinion interface. This part is a direct fit for vehicles such as the Toyota Tacoma, Toyota Highlander, and Lexus IS250 in the rear position, making it a practical replacement for service work on the differential assembly. If you are replacing a worn seal on a Toyota Camry, Toyota RAV4, or Scion tC, WS710871 provides the dimensional consistency needed for a proper repair.

Common Problems This Part Can Address

• Gear oil seepage around the differential pinion area.
• Contamination entering the differential through a worn seal.
• Loss of sealing integrity from age, heat, or fluid exposure.
• Noise or driveline concerns related to low differential fluid level.
• Service issues caused by a damaged rear pinion seal.

Installation Notes and Tips

Confirm the rear differential application and compare the shaft diameter, housing bore, and outside diameter before installation. Clean the sealing surface thoroughly and inspect the pinion area for wear or damage that could affect seal performance. Verify fitment against the vehicle listing for the exact model and year before installation on Toyota, Lexus, or Scion applications.

Quality Assurance

InMotion manufactures this seal with precision-focused construction and durable fluoro-elastomer material to support dependable sealing performance in differential service.
