It uses a bonded rubber outside and inside diameter for easier, piloted installation and is designed to handle the heat and movement of heavy-duty truck axles. You replace this seal whenever you're doing a wheel-end service, like a brake job or bearing repack, to prevent oil leaks that can ruin brake shoes and cause wheel-end failures.
