When I bought my truck both front tires were severly worn on the outside., When I pulled the hubs to put in new seals and one piece boots I checked the bronze bushings and they looked/fit great but the pass tire still looks crooked, I also replaced my shocks but only because I found a pair cheap. Bad shocks ( on any vehicle ) would only cause chopping/cupping on the outer part of the tire ( from tire consantly bouncing ). Unfortunatly I've only been on one long trip (220 miles ) since I redid the front and the replacement tires don't look bad since doing that trip
