What is a symptom of a vehicle that has been misaligned?

A steering wheel that is off-center is indeed a common symptom of misalignment in a vehicle. When the wheels of a vehicle are not aligned properly, it can cause the steering wheel to sit at an angle, even when the vehicle is traveling straight. This misalignment affects the relationship between the front wheels and the steering mechanism, leading to uneven handling and an inappropriate steering response.

When the wheels are aligned correctly, the steering wheel should be centered when driving straight. If a driver notices the steering wheel is tilted to one side, it indicates that the wheels might not be parallel, which can lead to a range of handling problems and potentially compromise safety.

Other symptoms, like reduced fuel efficiency or increased tire wear, can indeed be associated with wheel misalignment as well, but the most direct and noticeable symptom when driving is the off-center steering wheel. Vibration at high speeds may be attributable to various other factors, including tire balance issues, and while it's true that it can accompany a misaligned vehicle, it is not as definitive a symptom as an off-center steering wheel.
