Abstract
A preloaded tie rod end assembly for a motor vehicle steering system and a method for making the assembly is disclosed. The tie rod end is made by positioning the ball of a ball stud against a pair of frangible bearings within the socket portion of a tie rod end housing. A plastically deformable element is also situated within the housing. A closure member for the housing exerts a force against the bearings during the assembly operation and causes each bearing to fracture into circumferentially spaced bearing pieces. After the tie rod end is assembled, an axial load is placed upon the ball stud which is transferred to the deformable element thereby causing it to deform. The element is deformed to the extent necessary to bring the frictional resistance to rotation of the ball stud about its own axis within a prescribed torque range.
