I never could get mine to center. I had new springs, bushings, drag link, and tie-rods. Something was not correct, but the truck drove fine, steering wheels just not centered all the time. I had a rod made with left and right threads, then used replacement tie-rod ends for an adjustable drag link. It's surprising how little you need to turn it to change the wheel position. Also, with the gear box centered and adjusted properly, high driving is no longer a chore. I can drive miles with very little steering wheel movement.
