Corteco 12015557B Differential Shaft Seal

Description

The Corteco 12015557B is a differential shaft seal designed to prevent lubricant leakage from the differential and keep contaminants out. This seal is critical for maintaining proper differential function and preventing damage to internal components. It’s typically used in the drivetrain of vehicles, ensuring smooth and reliable power transfer to the wheels. This high-quality seal offers exceptional durability and resistance to wear, extending the life of the differential and reducing maintenance costs. It measures 114 x 105 x 105 mm and is manufactured in Hungary.

Key Features & Benefits

This seal’s job is pretty simple, actually. It keeps the gear oil inside your differential, and keeps dirt, water, and other nasty stuff outside. It’s a pretty crucial little component, just a rubber ring really, but it does a big job. It sits right where the axle shaft goes into the differential housing. Think of your differential as the thing that lets your wheels turn at different speeds when you’re going around corners. The shafts are spinning, and that seal is the barrier. It prevents the oil that lubricates all those moving parts from leaking out. Without that oil, everything grinds up pretty quickly. It's part of what allows power to actually get to your wheels.

Symptoms, Risks & Replacements

If this seal fails, you’ll notice if you see oil leaking around your wheel area, especially after you've been driving. It’ll usually be a reddish or brownish color, depending on the type of gear oil you have. If it gets bad enough, you could end up damaging other parts—bearings, axles—because they’re not getting the lubrication they need. It’s a relatively inexpensive part to replace, and doing it before it causes bigger problems will save you a lot of money and headache. Places like Fixparts Online usually have these in stock, and they're a fairly straightforward repair if you’re comfortable working on cars. If not, definitely take it to a mechanic.
