Yes they were after market A arms.....stock A arms you cannot put just the joint in it. That's what I was saying if the OP had after market A arms (there will be a C clip or Circlip around the bottom of the joint itself) he could change JUST the ball joint.

 

not on the press fit ball joints. you could spend hours hammering and they wont budge, well that was the case for me. but then again ny winters are terrible on cars/trucks

 

even in cali you cant hammer those things out, you would bend the upper a-arm before you would get that bj out, thats why they make bj presses that you can pick up at harbor freight for a reasonable price

 

an upper ball joint available for the press in arms. It's part number is K80014T. (The "T" may not be necessary, depends on your auto parts dealer). It requires a ball joint press to install.
