Abstract:
An aftermarket retrofit kit is used to prepare control arm bosses of automotive suspension systems to receive new, replacement ball joints. The kit includes a special cutting tool for forming obtuse threads in the apertures of aluminum suspension system mounting bosses for replacement of spent or used steel ball joints originally pressed-fit into forged aluminum control and steering arms. Since unthreaded apertures of bosses of control and steering arm joints in which the original pressed fitted equipment ball joints may be threaded to receive the new joints, avoidance of having to replace expensive original control and steering arms is made possible by the reuse of such arm parts normally discarded. A separate alignment block is included to assure accurate piloting of the cutting tool. Threading of the control arm bosses can be done on or off of the vehicle, and separate kits are provided for upper and lower control arms.
