Just put new heavy duty u-joints in the front after 210,00 miles and now it feels that my steering does not want to return to center. I have an AGR steering box that is about 4 years old, no leaking and I have tried to adjust it with no luck. I have also have the borgeson shaft. The ball joints and drag link all look good. A friend says that the steering box is bad. Anyone have this problem, I don't want to replace the box unless I have to. Thanks...
