• Prevents oil leaks that can cause hub and axle damage
• Ensures proper lubrication of wheel bearings for longevity
• Stops contaminants from entering and damaging internal components
• Maintains optimal drivetrain performance and efficiency

Replacing the front and rear outer hub oil seals on your Defender, Discovery 1, or Range Rover Classic is crucial for preventing oil leaks that can lead to premature bearing wear and potential axle damage. These seals keep lubricant contained while blocking out dirt, water, and debris that could compromise internal components. Over time, seals degrade due to heat, friction, and exposure to harsh conditions, leading to leaks and contamination. Replacing them ensures proper lubrication, extends component life, and maintains drivetrain efficiency, reducing the risk of costly repairs.
