With the shafts removed, cut the cotter pins off of the upper and lower ball joints and loosen the castle nuts. We are replacing the ball joints so we’re not concerned that the pickle fork will damage the rubber boots on them. A few good taps with the hammer should separate the two components. In lieu of the pickle fork, several solid whacks with a maul or heavy hammer on the inner C around the upper ball joint should free the knuckle. Leave one of the castle nuts threaded on the end of a ball joint to keep the steering knuckle from falling on the floor when it breaks free.
