RETAINER RING

The output shaft seal of the differential in a Citroen DS is a crucial component that helps prevent oil leaks from the differential. This sealing ring ensures that the lubricant remains inside the system, which is vital for the smooth operation and longevity of the differential. It is designed to withstand high pressure and friction, and helps maintain the vehicle's performance and efficiency. Regular inspection and replacement of this seal, if necessary, can prevent costly repairs and vehicle downtime, ensuring the durability and reliability of your Citroen DS.
