I am saying 100% without a doubt that all those people built their steering racks wrong. Its a not so great design, and when you add first time builders(first time building that rack), you get problems. Once that servo saver is stripped once its done for life. It needs to be tightened all the way for best performance. Anything less than full tight will cause way too much slop with the stock spring. If its stripped or left way loose it will bind the steering.
