Abstract: Embodiments of the invention are directed to a lower ball joint assembly for connecting a lower control arm to a steering knuckle of a vehicle. In one embodiment, the lower ball joint assembly comprises a plurality of components including a ball-head tapered ball joint pin (or stud), a ball joint housing and a securing ring configured to assemble together into a lower ball joint assembly. In an assembled configuration, a proximal, or ball-head, of the ball-head tapered ball joint pin may be housed within the ball joint housing. The securing ring may reversibly couple with a distal end of the ball joint assembly by a plurality of fasteners to complete the assembly. The ball joint assembly may have a hardness characteristic of between forty (40) and one-hundred (100) Rockwell.
