The invention relates to a device and method for determining and adjusting the chassis geometry of a vehicle. In order to provide a device for determining and adjusting vehicle chassis geometry, which can be manufactured as inexpensively as possible, the invention proposes that two tracks be provided on which the vehicle can be moved from a position A to a position B, each track having two means to permit lateral relaxation of the vehicle wheels as well as rotary discs located in the area of the vehicle's front axle at position B, that a measuring sensor operating according to the principle of stereophotogrammetry is located on the outside of each of the tracks, and that means for measuring the travel of the measuring sensors and a steering-wheel balance for detecting the position of the steering wheel are provided. This configuration of the device makes it possible to create a chassis-geometry testing and adjusting rig that does not require floating plates with driven roller pairs for uniform rotation of the wheels but still permits reproducible toe and camber-angle measurements accurate down to angular minutes.
