If you are part gorilla like us, pay attention to how far into the joint you shove the shaft. We jammed this one too far, and then we were left wondering why the joint lacked angularity once we installed it. Once we pulled it back out, we smacked ourselves in the head. This also shows why having a square shaft end is important. If the shaft was cut off-square, then the long end could interfere with the full travel of the joint.
