Check your toe. You can do this be raising the truck, measure up from the floor a specified distance, about mid tire, mark the tire either with tape or a grease pencil and do the same for the other tire. Measure the distance between these two points on the tire then rotate the tire 180 degrees and measure this on the back side where you marked them before rotation. I went to three alignment shops with my truck, each claiming that the tire balancing and alignment were incorrect within a 2 week period. And they all had various makes of Hunter. I have concluded that these machines are not calibrated. You can do this also with the suspension loaded by leaving the wheels on the ground. I am keeping this short as there is a lot more to this. Good Luck.
