Abstract
An improved method of manufacture for an isolated cross-axis ball joint, utilized in an articulated torque-rod end, wherein an isolated outer cylindrical element is chemically mold bonded to a pre-curled intermediate sleeve to provide isolation there from. The inner bearing element is comprised of a heat-treated spherical inner sleeve that rotates upon two lubricated plastic bearing races and two seals with encapsulated steel washers in each seal. The intermediate sleeve is pre-curled or manufactured at one end so as to retain a first seal. The first bearing race is then dropped in, followed by the heat-treated spherical inner sleeve, followed by the second ball race and the second seal. The second end of the intermediate sleeve is then fixed by compression and implementation of a retaining means, such as curling to close the bearing element. The seals provide the wear compensation of the ball joint by adding compression after the fixing of the intermediate sleeve.
