The invention relates to a device for checking the wheel suspension (7, 8) of a vehicle (2), in particular a motor vehicle (2), comprising: (a) a device (10, 12) for determining the wheel normals and/or the rotational center (Z) of a wheel (4a, 4b) of the vehicle (2); (b) a device (10, 12) for detecting the movement trajectory (p(t)) of the wheel normals and/or the rotational center (Z) of the wheel (4a, 4b) during a movement of the vehicle (2); and (c) a comparing and analyzing device (14) which is designed to compare the detected movement trajectory (p(t)) of the wheel normals or the rotational center (Z) of the wheel (4a, 4b) with a specified movement trajectory (K) and to output an error message if the deviation of the detected movement trajectory (p(t)) from the specified movement trajectory (K) exceeds a specified threshold.
