Saturday i was taking my roommate to the rugby fields and when i go to turn around my right front tire went up on the curb, now this is something that happens everyday and is no big deal, but this time it was. As i was driving off the truck started to pull hard to the left with the steering wheel straight and then after i made a right turn it would pull hard to the right then back again after a left turn. When i got home i checked everything out and nothing looked bent or was binding up, now remember this was only a curb, so i have no clue what could have caused this problem. If anyone could please give me and idea about where to start before i take it to an alignment shop this week
