Axle Seals

Axle seals are vital drivetrain components that prevent fluid leaks where the axle shaft enters the transmission or differential housing. They keep lubrication inside while blocking dirt and water. A CV axle seal is used in front-wheel-drive or all-wheel-drive vehicles, while a rear axle seal is located in the rear differential to contain gear oil. An axle seal leak can result from wear, heat, or improper installation, showing signs like fluid around the seal, burning smells, or unusual drivetrain noises. If ignored, leaks may lower fluid levels and damage gears or bearings. Regular inspection of axle seals, especially CV axle seals and rear axle seals, helps prevent costly drivetrain issues.
