The cost of a standard wheel alignment usually includes adjusting the toe, camber and caster angles, as well as having the technician check the car's steering, tires and suspension. The service does not include the cost of replacement parts or their installation.
Wheel alignment requires special tools, which most home mechanics cannot access. Garages typically offer either front-wheel alignment or four-wheel alignment. Four-wheel alignment is the better service, but usually costs more.
Before the alignment, the technician often takes the car for a test drive. After the alignment, it should drive like new without any drift or vibration. However, hitting a curb or pothole can affect the alignment and cause the vehicle to need the service again.
