My 2008 access cab 4x4 wanders quite often, I had a 79 f250 with 40" tires and it compares to that! This truck I bought 6 months ago, I had all the wheels balanced and an alignment checked, they said its good and nothing needs to be done. I have been to 2 shops now, they both did test drives and said nothing is wrong....quick tests though....This may sound funny but I can't take my eyes off the road at all or I am wandering off somewhere easily! This is a stock truck as far as I can tell! No accidents recorded etc. Is there something else I can do to fix the wandering issue? Its winter and I have no garage to play in, was thinking of checking for play everywhere, it has 60,000 KM on it now. I guess when spring comes I can check it all out but thought maybe these certain models have an issue with a part wearing out every 30,000km or so(like rear axle to spring mounting hardware for example). I had a car with this issue with its front hub bearings assembly lol. Thanks!
