Corteco 49378518 Wheel Hub Shaft Seal

Description

The Corteco 49378518 is a wheel hub shaft seal designed to prevent lubricant leakage from the wheel hub assembly. This seal is critical for maintaining proper wheel bearing lubrication and preventing contamination from dirt and water. It's commonly used in a variety of vehicles to ensure smooth wheel rotation and long-lasting performance. This high-quality seal is manufactured in Taiwan and measures 15 x 92 x 92 mm, providing a precise fit and reliable sealing capabilities that contribute to extended bearing life and reduced maintenance costs.

Key Features & Benefits

This little seal’s job is pretty simple, really. It prevents grease from leaking out of your wheel hub and keeps dirt and water from getting in. It sits right where the axle shaft comes out of the hub assembly. It's basically a barrier, a sort of gasket if you will. Think of your wheel hub as the center of the wheel, where it spins. Inside that hub, you’ve got bearings that need to be lubricated with grease to keep everything turning smoothly. The shaft seal keeps that grease where it belongs, and stops nasty stuff from damaging the bearings. It’s part of the whole suspension and steering system, ensuring your wheels move as they should.

Symptoms, Risks & Replacements

If this seal fails, you’ll start losing grease. That means the bearings will quickly wear out. You'll notice if it’s really bad—you'll likely get a grinding or rumbling noise coming from the wheel, especially when you turn. It can even lead to wheel wobble or, in a worst – case scenario, bearing failure while driving, which is obviously a safety issue. Replacing it is a lot cheaper and easier than replacing a whole hub assembly or dealing with a breakdown. You can find these fairly easily, actually – a lot of folks get them from places like Fixparts Online, but any good auto parts store will carry them. They’re a small part, but they do a big job.
