Abstract

The wheel alignment kit and method related to a wheelless alignment technique employing a pair of alignment fixtures which cooperate with a corresponding pair of turntables to support the vehicle in place of its wheels and to facilitate easy access to the strut assemblies of the vehicle for alignment purposes. The kit also includes an electronic camber gauge tool adopted to be mounted on the fixtures to provide a user with an instantaneous camber reading. A pair of toe gauge tools adapted to be mounted on the fixtures cooperate with a datum line to provide the user with an instantaneous toe reading.
