Autopart International 1776-520375 Pinion Seal

The Autopart International 1776-520375 is a precision-engineered pinion seal designed to prevent differential fluid leakage at the pinion shaft. This critical seal creates a tight barrier between the differential housing and the pinion gear yoke, ensuring proper lubrication retention and protecting internal components from contamination.

Key Features:

• High-quality seal construction designed for reliable sealing performance
• Engineered to withstand differential operating temperatures and pressures
• Prevents gear oil leakage and contamination at the pinion shaft
• Direct replacement seal for specific vehicle applications
• Manufactured to meet OE specifications for proper fit and function

Regular inspection and replacement of pinion seals helps maintain proper differential lubrication and prevents costly damage to ring and pinion gears. A failing pinion seal often shows signs of oil leakage at the front or rear of the differential housing near the driveshaft connection.
