It's designed to keep the axle lubricant inside the hub and to stop dirt, water, and other contaminants from getting into the wheel bearings on heavy-duty trucks and trailers. You replace this seal whenever you service the wheel bearings or if you notice an oil leak around the hub. This unitized, nitrile seal uses a spring-loaded main lip and patented SURE-LOCK ribs on the inner and outer diameters to create a reliable, long-lasting barrier.
