What do ball joints consist of?

Ball joints consist of a metal housing and stud.  The stud can swing and rotate within the housing.  Bearings inside the housing can be comprised of metal or plastic.  The socket is filled with grease to provide lubrication, keep debris and water out of the socket, and maintain noise free operation.  A rubber boot opening of the joint to keep debris out and grease in. Many original equipment ball joints are designed as sealed units. If the protective boot fails, water and road debris will quickly cause wear and ball joint failure. Our Tomoi aftermarket ball joints use an improved design that allows lubrication to flush out contaminants to extend the life of the joints.
