Help keep dirt, dust, and moisture away from the rear wheel bearing and hold its grease where it belongs with the Schaeffler Rear Wheel Seal / Shaft Seal S34384.

Schaeffler lists this part under two names, wheel seal and shaft seal. Its wheel seals are designed to protect wheel-end components from contamination and to prevent grease from escaping the bearing. Wheel-seal requirements are demanding and vary by application, position, and vehicle class. This seal is cataloged for the rear position on the applications above.
Signs this part may need replacing: grease seeping onto the inside of the wheel or brake parts, a wet or contaminated rear hub area, or seal damage found during brake or bearing service. If a leaking rear wheel seal is the cause, this part replaces it. Inspect the bearing and brakes as directed by the vehicle service procedure.
