I have what feels like excessive freeplay in my steering wheel.The truck seems to track true at speed..doesn't pull to either direction,but the steering wheel seems to have a lot of play in it.Has anyone ever adjusted their steering box? How hard is it to check for excessive play in the steering box,and adjust it? I've done manual GM boxes before,but this would be the first power steering box I've done...Any ideas?...TIA...John
