doing a brake swap on my 76 dart sport and a long story short i cant separate the upper ball joint from the knuckle tried a pickle fork nothing even used an air hammer its on there like steel the nut and cotter pin came off pretty easy any tips?

Take the control arm off and spindle and use a press. Have you tried putting the nut back on and whacking the nut/tip with a hammer.
