Coming home this evening I noticed almost straight away that the car pulls strongly to the right. Am I right to assume this means the tracking needs adjusting? If so, am I best to go to a main dealer, or one of these tyre and exhaust places, or even Halfords? I can't understand how it happened, as I have not hit a kerb, I checked the car and there is no sign it was hit while parked, and there are no signs of kerbing on the wheel covers. I did not notice anything on the way to work. Most odd. Or could this be a power steering issue?
