Upper Control Arm disaster

probably both. I was using a rubber mallet to pound the QA1 arms into place. I hit that little tab where the bumper is supposed to hit. There was very little weld on either side and it popped right off. I looked at the matching one an it looked like it had a lot more weld on it.

The original arms I wanted to replace because I was unable to get the ball joints out, and also unable to push one of the bushings all the way out, and slightly bent the arm doing so with a hydraulic press, only after buying and breaking one of these tools (stripped the damned threaded rod) trying to get the bushing out with one of those hand tools.
