Made from durable polyacrylate material Prevents oil leaks and protects drivetrain components Best replaced when renewing the splined sleeve This Corteco differential splined sleeve outer oil seal is designed for Freelander 2 and Range Rover Evoque models with the 6-speed AWF21 AWD automatic transmission. Manufactured from durable polyacrylate, it offers excellent resistance to heat, oil, and wear, ensuring a long-lasting and reliable seal. As the splined sleeve wears over time, it's good practice to replace the outer oil seal during renewal to maintain a leak-free system and protect the transmission. This high-quality seal helps preserve drivetrain performance and prevent costly fluid loss or damage. .
