I had my truck to the dealer twice for a slight pull to the right. It's more of a drift then anything, but irritating. First time I don't think they did anything, the second they sent it out to a tire shop and said they adjusted the tow in/out which I believe, as I checked underneath and saw scratch marks where they used a wrench. However it is still drifting to the right, I first thought it may be the crown in the road but even in the middle of the road I can not let go of the steering wheel and go straight. I am afraid that my complaint may re-adjust the pull but set the tire alignment off causing excessive wear on the tires if I complain anymore. I am just looking for some advise as I want to get this in before my warranty runs out.
