ACDelco Differential Drive Pinion Seal

The ACDelco Differential Drive Pinion Seal (also called a differential pinion seal or rear axle pinion seal) keeps gear oil inside the differential housing. It also keeps dirt, dust and moisture out. The seal fits where the driveshaft yoke or flange enters the differential. It helps protect the internal gears and bearings from contamination and lubricant loss.

Key Features:

• Sealing design that retains differential gear lubricant at the pinion shaft
• Helps keep out road debris, water and contaminants
• Built to meet ACDelco's quality standards for durability and consistent performance
• Resists the heat, friction and constant rotation found in drivetrain applications
• Helps prevent the leaks that can lead to low gear oil, noise and premature differential wear

ACDelco is General Motors' parts brand. Its seals are engineered for reliable sealing and long service life, whether you are doing a repair or routine drivetrain maintenance. Replacing a worn pinion seal when you service the differential helps protect the drivetrain and keep the axle running smoothly.
