So, did you get the ball joints out and the new ones in?
I just did mine on the 72 Scamp. Used the same size socket also. It was definitely a bit loose. But it worked. That was a lot of work especially for someone our age. The right side one broke loose using a four foot breaker bar and had to keep using that bar until it was almost completely unscrewed. Tried the same thing on the other side and it wouldn't brake loose at all. Next step was to heat up the control arm around the ball joint. Should have done that first. It broke loose and turned off easily. Moral to the story, use heat unless you're young and dumb and full of,....... You know:rofl:
