Moog's innovative approach allows grease to flow through the bearing to the stud and provides a smooth, durable surface that extends service life. Moog's design also transfers the load to the housing and provides strength and stability. Boots are sealed for durability and grease relief valves allow debris to be flushed out when ball joints are serviced.
