I would swap the box I just helped a friend with his 1996 chevy had the same problem would not return to center and hard to right the parts house box was junk we just found a good used box problem was fixed. I have not had any luck with parts house boxes over the years. If still doing it after that I would look at your ball joints. You might have a friend turn the steering wheel and you watch the front end to see if anything looks abnormal or parts that are loose. What side of houston are you I ask because might be easier to see what it is doing in person I am on north side by lake conroe.
