There are several things involved in an alignment check. First, there’s an inspection of the steering and suspension – it should be checked to see if anything’s bent or broken. Then the tire condition needs to be inspected. From there, the vehicle is put on an alignment rack and an initial alignment reading is taken. If all four wheels are adjustable, they are lined up perfectly parallel with the vehicle’s center line. If the back wheels aren’t adjustable, the technician determines the direction they push and then aligns the front wheels to match.
