I tried a search on this, expecting that someone else would have had this on their Monty. I've replaced all the shocks with the factory ones, replaced upper and lower balljoints, tie rods, center link, and, idler arm twice. Wheel bearings are newer, and tight. Tire pressure is either at spec or 2 psi above it. Set the torsion bars to factory spec ride height, aligned the truck with our Hunter machine. Checked the control arm bushings for wear, didn't find any play yet. AND, still get a cupped tire wear pattern after about 15/20K total time mounted on the front, with me on the second set of Yokohamas that I've run with on this Monty since 2003. Any thoughts on what I might be missing? Happens only to the fronts, and I'm rotating the tires between 7/10K. Yeah, I probably should be doing them sooner, but you know how your truck is always the last one to worked on in your family <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
