It seals the front output pinion of the differential carrier, preventing gear oil from leaking out and dirt from entering. A failed seal causes axle lubricant loss and can lead to bearing failure, so it’s replaced during differential service or when an oil leak is spotted. Genuine Dana Spicer replacement with verified dimensions.
