ABSTRACT:
A rack and pinion steering assembly for automobiles and the like dirigible wheel equipped vehicles having a longitudinally driven rack bar connected to wheel turning tie rod linkage by ball and socket joints with thin wall, tubular metal housings or casings which are easily and inexpensively attached to the ends of the rack bar by deformation and which preload the bearings of the joints to maintain a predetermined torque on the ball studs and eliminate end play between the tie rods and the rack bar. The bearings of the joints include a bearing cup between the ball end of the stud and the rack bar composed of a resilient plastic material and a bearing ring between the ball of the stud and the free end of the housing composed of a stiff nonyielding plastics material with the cup and the ring cooperating to envelope the ball end of the stud and the tubular housing compressing the cup radially and axially so that it will expand as wear develops, preventing looseness in the joint, while the stiff bearing ring provides a stable high-tensile, nonyielding load support for the ball stud.
