Abstract: A chassis alignment system for a vehicle having steerable stub-axles comprises a pair of alignment tools. Each alignment tool comprises a rigid, unitary housing having a mounting receivable directly on the respective stub-axle and supporting the housing from the stub-axle in a fixed attitude with respect to the central axis of the respective stub-axle, the housing being adjustable in position around the stub-axle. Each housing accommodates a laser emitter which emits a beam parallel to the central axis of the respective stub axle, and further comprises a graduated target positioned to receive the beam from the laser emitter of the other alignment tool. Each target has a reference point positioned relative to the respective central axis, wherein the point of incidence of each beam on the respective target relative to the reference point enables the relative orientation of the stub-axles to be determined.

Abstract: A chassis alignment system comprising a first alignment tool associated with a toe-in/chamber target, the first alignment tool comprising a first housing accommodating a first laser emitting means, the first housing having a first mounting means adapted to enable the first alignment tool to be fixed to a first steerable axle and to be movable therewith, the first laser emitting means being disposed in the first housing at a predetermined distance from the first mounting means and adapted, in use, to emit a beam in a direction parallel to a first central axis, the first mounting means being further adapted to enable the first laser emitting means to be oriented about the first central axis of the first steerable axle into a selected orientation, the toe-in/chamber target comprising means to receive the first laser beam and provide an indication of the position at which the first laser beam is incident upon the target relative to a reference, the target adapted to be positioned relative to the vehicle to enable
