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. This seal’s job is pretty straightforward – it keeps the gear oil inside your differential and keeps dirt and water out. It's a circular gasket that fits around the axle shaft where it exits the differential housing. It spins with the axle and has to maintain a tight seal against the housing, even at speed. Think of your differential as the part that lets your wheels turn at different speeds when you’re going around corners. The axles are what actually deliver the power to those wheels. The differential shaft seal sits right where the axle shaft comes out of the differential. It's a crucial component in the drivetrain, making sure everything stays lubricated and functioning properly. Without it, things get messy, and quickly. Well, gear oil is vital for the differential’s gears. It keeps them lubricated, cool, and prevents wear. When this seal fails, oil leaks out. You’ll notice if it does, usually as a slick spot on the axle or under the vehicle. A leak isn’t just a mess, it means the gears aren’t getting the lubrication they need, which leads to damage, noise, and eventually, a very expensive repair. It’s also important to keep contaminants out—water and dirt can really mess up the gears. Ignoring a leaking seal is a short path to needing a complete differential rebuild. You can usually find these pretty easily, Fixparts Online carries a good selection, and replacing it is a lot cheaper than replacing the whole differential.
