Just a follow up. I have now installed a DT tracbar, had a tie rod replaced, had new front brakes (with rebuilt calipers) installed, along with upper and lower control arm bushings. I then installed a DSS and then did the over center steering box adjustment. The truck drives better than the day I drove it off the lot. Obviously, having in spec front end parts is a must. I think the component that made the greatest difference was the DSS although everything helped. I made sure to do the job in steps so I could guage each improvement. Hats off to Marv and Darin for the DSS!
