How do you replace lower ball joint 1992 Le Mans?

you remove the tire, use a ball joint splitter (too) to dissconect the ball joint from the wheel hub. Near the ball joint on the control arm, there are 3 rounded heads, you can either drill them out or take chisel and punch, and shave off the heads with the chisel and hammer. Then with the punch hammer out the bottom half of the rounded head. The replacement ball joint comes with 3 nuts and bolts, line the holes of the new ball joint and install with the 3 bolts.
