The Autopart International 1776-321720 is a rear outer differential pinion seal designed for professional-grade performance and reliability. This seal is engineered to prevent differential fluid leaks at the pinion shaft, maintaining proper lubrication and protecting critical drivetrain components from premature wear.

Key Features:

• Manufactured to meet or exceed OEM specifications for precise fit and function
• Constructed from application-specific seal material for maximum durability
• Designed to withstand the demanding conditions of differential operation
• Direct replacement for worn or leaking factory pinion seals
• Helps maintain proper differential fluid levels and system pressure

This differential pinion seal is a critical maintenance component that prevents costly fluid loss and contamination. Professional installation is recommended, and the seal should be replaced whenever the driveshaft is removed or during differential service to ensure leak-free operation.
