Corteco 49378734 Wheel Hub Shaft Seal

Description

The Corteco 49378734 Wheel Hub Shaft Seal is a critical component within the wheel hub assembly, responsible for sealing lubrication and preventing the ingress of contaminants like water, dirt, and debris. This seal is essential for maintaining proper wheel hub function and bearing life, commonly used in a variety of vehicle applications. This high-quality seal provides reliable performance and extends the life of the wheel hub assembly by minimizing friction and wear, and maintaining optimal lubrication. It measures 13 x 72 x 72 mm and is manufactured in Taiwan.

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.
