Detailed Description

WS710525 is a differential pinion seal engineered to maintain a tight seal at the rear outer pinion location. Its nitrile material is selected for sealing durability, helping keep contaminants out while retaining differential lubricant inside the housing. For Toyota Tacoma, Toyota Tundra, Toyota Sequoia, Lexus GX470, and other Toyota-axle applications, this seal supports consistent driveline protection where accurate dimensions matter.

This part cross-references no listed interchange numbers in the provided data. The part number WS710525 is the reference to use when matching this seal to the correct rear outer differential pinion application.

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination from road debris and moisture entering the housing
• Wear on internal differential components caused by lubricant loss
• Seal replacement needs during driveline service
• Maintenance on Toyota axle and 8.4in ring gear rear differential setups

Installation Notes and Tips

Confirm the rear outer position, axle type, and ring gear specification before installation. Match the seal dimensions to the housing bore and shaft diameter, and inspect the pinion surface for wear or scoring before pressing in the new seal. Clean the sealing area thoroughly so the nitrile lip can seat evenly and maintain contact.

Quality Assurance

InMotion manufactures this seal with precision-focused construction and high-quality materials for differential service. WS710525 is intended for applications where a reliable pinion seal is required to help preserve driveline integrity and reduce the risk of leaks.
