Corteco 12010684B Differential Shaft Seal

Description

The Corteco 12010684B is a differential shaft seal designed to prevent lubricant leakage from the differential assembly. This seal is a critical component within the drivetrain, ensuring the proper functioning of the differential and its gears. Manufactured in Hungary, this seal measures 114 x 105 x 105 mm and provides reliable sealing performance, contributing to extended component life and reduced maintenance needs. Its precision engineering ensures a tight fit and effective barrier against contaminants, ultimately enhancing drivetrain efficiency and durability.

Key Features & Benefits

This seal basically keeps the gear oil in the differential and keeps dirt and water out. It sits right where the axle shafts come out of the differential housing. It’s a pretty simple part, really, a ring made of rubber or a rubber compound, but it has a big job. It spins with the axle, so it’s designed to handle a lot of friction and constant movement. Think of your differential as the part that lets your wheels turn at different speeds when you’re going around a corner. That’s important. The shaft seal is part of that system, ensuring the gears inside are properly lubricated. It’s a crucial part of the drivetrain, so everything runs smoothly. It’s right there where the power is transferred to the wheels.

Symptoms, Risks & Replacements

If this seal fails, you’ll start to lose gear oil. You’ll notice if it does, because you’ll likely see an oil leak and maybe hear some unusual noises. Losing that oil means the gears aren't getting the lubrication they need, and that leads to wear and tear, and eventually, potential damage—expensive damage. It acts like a shield, preventing contaminants from getting in and grinding everything up. If you let a leak go on too long, you could end up needing to replace the entire differential. You can find these seals pretty easily, Fixparts Online has a good selection, and they aren’t too difficult to replace if you’re reasonably handy. But definitely address it quickly to avoid bigger problems.
