I have an 05 z71, 5.3 extended cab. When I bought the truck new before driving it off the lot I had the dealership swap out the 265's for some 35" pro comps. Of course this necesitated cranking on the torsion bars, followed by a realignment. When the truck was brand new it felt fine but now about 9 months old I notice a loose rattling feel in both the steering wheel and in the floor boards when I drive over minor roadway bumps. Anybody experience this? and if so what needs to be done?
