Ensure Optimal Performance with Racing Diffs Large Oil Seal for Haldex Transfer Case The large oil seal that fits between the Haldex transfer case and the rear differential is crucial for maintaining the health of your drivetrain. A broken or leaking oil seal can lead to premature clutch wear inside both the Haldex unit and the rear e LSD. This happens because leaking oil allows the fluids to mix, preventing the oil pumps from creating the necessary pressure to operate the clutch stacks effectively. Why Replace Your Oil Seal? Prevent Premature Wear: A faulty oil seal can cause rapid wear of the clutch stacks inside the Haldex and rear e LSD due to oil mixing and inadequate pressure. Maintain Optimal Function: Ensure that Haldex oil and rear e LSD oil do not mix, preserving the performance and longevity of your drivetrain. Essential for Drivetrain Service: It is highly recommended to replace the oil seal during any drivetrain service to prevent future issues. Key Benefits: High-Quality Construction: Made from durable materials to ensure a long-lasting seal and optimal performance. Essential Maintenance: An important component for anyone performing Haldex or rear e LSD repairs or maintenance. Easy Installation: Designed for a perfect fit between the Haldex transfer case and the rear differential.
