I had the same truck and the previous owner put wider wheels with the stock straight axle. Steering and wander was problematic. Installed new king pins, put on a steering damper to help the steering as a last resort. The steering still wandered and lurched with road crown after front end alignment to specifications. Narrower tires helped a lot more by keeping with what GM engineers designed. Put stock rims back on with radial tires.
