Description

This differential output shaft seal seals the output shaft on the rear axle differential and reliably prevents transmission oil leakage. With its precise fit and high-quality material, the sealing ring ensures a long-lasting, stable seal and protects the differential from oil loss, dirt, and increased friction.

In both classic and modern Porsche models, these seals are subject to typical aging processes. Early symptoms such as damp patches, dripping, or noises can indicate a defective seal. Replacing them during a service or transmission repair restores the full functionality of the drivetrain.
