Autopart International 1776-321714 Differential Pinion Seal

The Autopart International 1776-321714 is a precision-engineered differential pinion seal designed to prevent gear oil leakage from the differential housing. This seal creates a tight barrier around the pinion shaft where it exits the differential, maintaining proper lubrication levels and protecting internal components from contamination.

Key Features:

• Precision-molded construction for reliable sealing performance
• Durable rubber compound resists heat, oil, and wear
• Metal case provides structural integrity and proper fitment
• Prevents differential fluid loss and contamination
• Direct replacement for worn or leaking factory seals

Pinion seals are critical maintenance components that should be replaced whenever the differential is serviced or when leaks are detected around the pinion yoke area. Regular inspection and timely replacement help prevent costly differential damage caused by low fluid levels.
