Just put a power steering pump, and steering box, as well as a new yolk in my 2006 Silverado 2500. When driving, although the steering is tight, the steering wheel has about 1 inch of play in it. Is there a way to tighten this up. There's only 217,000 miles on the old girl (diesel), and I expect more out of her. Thanks in advance.

 

The steering box should have an adjustment on it.
