ACDelco Differential Drive Pinion Gear Seal

The ACDelco Differential Drive Pinion Gear Seal, also called a differential pinion seal or rear axle pinion seal, helps keep gear oil inside the differential housing. It also helps keep dirt, water and road debris out of the housing. The seal fits where the drive pinion shaft exits the differential, so it protects the internal gears and bearings from contamination and lubricant loss.

Key Features:

• Seals the drive pinion shaft against differential gear oil leaks
• Helps keep contaminants out of the differential
• Helps protect the pinion bearings and gears from premature wear caused by low lubricant
• Made by ACDelco, General Motors' parts brand, to meet demanding quality standards
• Designed as a replacement part for a worn or leaking pinion seal

Replacing a leaking pinion seal promptly helps maintain correct differential fluid levels and extends the life of the driveline. Select the child item that matches your application.
