My truck pulls to the left when I drive on pavement. I've taken it to an alignment shop who said they couldn't fix the pull but adjusted some other things into spec. Just LOOKING at my truck, I could tell the front axle seems shifted to the left, with the rear axle shifted towards the right. Each axle is shifted about an inch away from center. I can't see how the lift alone would cause this, and nothing looks bent or out of place looking at the suspension. Whats the fix for this?
