This seal prevents dirt and moisture from entering the bearings and joints of the control arm, thus extending the suspension's lifespan and functionality. It is specifically crafted to fit the Citroën CX model, offering precise dimensions and materials for an effective seal. Regular inspection and replacement of this part can contribute to smoother driving and reduced wear on suspension systems.
