Parts Master Differential Pinion Seal

The Parts Master Differential Pinion Seal line gives you replacement differential pinion seals (also called pinion oil seals or drive pinion seals) for cars, trucks and heavy-duty drivetrains. The pinion seal sits where the pinion shaft or yoke exits the differential housing. It keeps gear oil inside the housing and keeps dirt, moisture and road debris out.

Key Features:

• Replaces a worn or leaking differential pinion seal
• Helps keep gear oil in the differential, protecting the pinion bearings and gears from wear
• Helps keep outside contaminants out of the differential housing
• Sold under the Parts Master brand, part of the Power Train Components line of drivetrain parts
• Each part number is built for a specific application, so choose the part number that matches your differential

Typical signs of a failing pinion seal include gear oil leaking near the pinion yoke, a damp or oily differential nose, low differential fluid and whining or noise from the axle. Replacing the seal promptly helps prevent more costly differential damage. Replacing the pinion seal is also a good time to check the pinion yoke surface and the differential fluid level.
