Also let me mention that my 2005 van has 30,000 miles on it and I did not adjust the steering box. My 2002 van has 200,000 miles on it and I adjusted the steering box before putting on the stabilizer. I turned the allen head screw one half turn in. It helped a good bit, but then the stabilizer really made it great. My suggestion would be to put the stabilizer on and then work with the steering box from there if need be. Got a much more car like steering feel to it and stability.
