Front Lower Ball Joint (3689901) by Lemfoerder®. Quantity: 1 per Pack. Ball joints are used in tie rods, control arms and stabilizer links, for instance. A ball joint consists of a supporting joint and ball stud and is free-moving in three directions. Traction forces, compressive forces and radial forces are transferred in these three directions with hardly any losses at all. Minor losses occur as a result of friction. Therefore, Lemfoerder uses premium materials for the ball and shell. The exact designation of the ball joints is derived from the transferred direction of force: angle joints transfer radial forces, axial joints transfer axial forces.
