For example when I am driving on a straight road and I hit a slight bump with the right wheel my steering wheel will turn to the right. If I hit a bump with my left wheel it does not go to the left it stays straight. I've had many wheel alignments now to the point where my left turning signal cancels less then a 1/4 of a turn and it takes almost 1/2 turn to the right for the "right" indicator to cancel. Every 3,000KM my toe is always off. They keep adjusting it because my steering wheel always goes off center to the right only. What could be the problem, my tires and rims were replaced I currently have 16,000km. What part of the suspension would cause the toe to get out of alignment? Would it be the tie rod ends? I have been to the dealer so many times and they keep telling me there is nothing wrong with the suspension. I need help on what the issue could be. Thanks
