Check and see if your idler and pitman arms are shot. Jack the truck up, wobble the tire and watch to see if the centerlink moves around without the pitman arm moving. That will make it feel like crap on snow and ice. Mine felt fine cranked up until they wore out, now it pulls all over on icy roads. Gonna replace them, and probably look at getting the braces from cognito so they won't wear out so fast.
