Wheel alignment involves adjusting a vehicle's suspension and the wheels' angles so that all wheels are parallel and perpendicular to the ground. Wheel misalignment can be caused by factors such as hitting a curb or pothole, driving on rough roads, or simply wear and tear over time. If your vehicle's wheels are not properly aligned, you may notice premature tire wear, uneven tread wear, or your vehicle pulling to one side while driving.
It is recommended that a vehicle's wheel alignment be checked frequently if the vehicle is driven on rough roads or in extreme conditions. Wheel alignment can be done at most auto repair shops and tire dealerships.
Toe alignment adjusts the vehicle's wheels to make them parallel to each other. Camber alignment adjusts a vehicle's wheels to ensure they are perpendicular to the ground. Caster alignment adjusts a vehicle's wheels to ensure they are parallel to the ground and improves steering.
