You need to hoist the vehicle into position before taking off the wheel and tire for lower Ball Joint replacement work. Set the lower
Control Arm aside and clamp it securely in the vice that rests on a bench. Press the lower Control Arm in a vice and apply a chisel to remove 4 securing points on the Ball Joint body before using a press to pull out the Ball Joint. Press the Ball Joint into its space by using its outer face only. Prepare the new Ball Joint using the press before returning the lower Control Arm to the bench vice and fitting it with 4 crimps through punch work according to the original Ball Joint placement. Install the lower Control Arm, put back the tire and wheel, make the vehicle descent, and complete alignment testing.
