when i removed the spindle pin from a friends s30, we put the spindle in the vice and put the control arm on the bench to counter act the force of hitting it with a hammer, then we bought a gallon of PB, broke out the oxy/acy torch, got the metal VERY hot, poured some PB on it, let it soak for 7 minutes, took a 10 pound sledge whacked it for 5 minutes. Ended up repeating that process about 4 time and it finally came out.
When i pulled my own spindle pins by myself, I got two gallons of PB in a small bucket and let the entire spindle soak, from a couple inches on the control arm to the entire spindle itself for about 24 hours, then i put it in the press. after about 30 minutes with the torch and even more PB, it came out fairly easy.
