Abstract: A vehicle gauging apparatus (1) including a datum bar (2) and a pair of first carriage assemblies (10) slidably mounted to said bar. Attachment means (12) are adapted releasably to secure each carriage (10) to a respective datum point (15) on the vehicle (16) and thereby attach the datum bar (2) to the vehicle. A trammel bar (20) is connected to one end of the datum bar (2) by connection means (21) adjustable to selected positions along the datum bar. The connection means permits at least a limited degree of universal movement of the trammel bar (20) relative to the datum bar. Reference means (32) on the trammel bar (20) provide a comparative indication of misalignment in the vehicle (16).

Abstract: A gauge apparatus for measuring the displacement of components, particularly automotive components. The gauge includes a support member adapted for secure attachment to one component, such as an automotive wheel. A transverse gauge bar is slidably interengageable with the support member and carries a rotatable gauge member at one end for measuring the displacement of the gauge member with respect to the gauge bar. The apparatus can be used to check the alignment of Macpherson strut suspension systems as well as wheel castor, camber, toe-in and alignment. A Macpherson strut straightening apparatus is also disclosed.

Abstract: The present invention relates to a device for assisting in the alignment of the rear wheels of a front wheel drive vehicle. More specifically the device is used to measure the angular displacement between a horizontal datum perpendicular to the desired forward direction of the vehicle and a horizontal line perpendicular to the axis of rotation of the rear wheel.

Abstract: A vehicle frame alignment apparatus comprising a pair of substantially parallel tracks upon which a vehicle may rest, at least one transversely extending beam suspended beneath the tracks, the beam being longer than the spacing between the tracks and having an upright pillar at each end thereof, the pillars being respectively on opposite sides of the pair of tracks and provided with anchorage means for attachment of straining members for applying a plurality of variously directed loads to the vehicle, the beam being suspended beneath the tracks by a pair of suspension units, each suspension unit comprising a top and bottom carriage mutually interconnected by a substantially vertical shaft so as to be relatively rotatable about the axis of the shaft, each of the tracks having fixedly associated and extending substantially parallel therewith a pair of longitudinally extending track rails spaced one from the other along which top carriage rides, the transverse beam having fixedly associated and extending substan
