I'm not sure if everyone had this problem, but after connecting the right leg to the pelvis, the links to the hydrolic cylinders were loose on my terminator. After installing all the other wobble fixes, I decided to try something on them as well. It was very simple. I took some leftover tubing from the finger assembly and used it in the joint on both the quadricep cylinder and ham string cylinder and it worked great. Just thought I'd pass it along.
