A vehicle wheel alignment and checking apparatus for front and rear wheels in which the apparatus has active light beam projecting instruments mounted on the front wheels to project beams longitudinally and transversely between the wheels of the vehicle, passive wheel position instruments on the wheels for reflecting incident beams to the active instruments, a system of mirrors associated with the active and passive instruments and beam targets for utilizing the system of mirrors and targets to find the alignment information, and alignment data indicators responsive to the manipulation of the active instruments and responses from the passive instruments for visually revealing the alignment data and aiding in adjusting the wheels to specified alignment values.

The combination of active and passive instruments for use in determining the alignment relationship between the front and rear wheels of a four wheel vehicle, the instruments of the combination comprising: (a) passive instruments on each of the rear wheels, each having a light beam reflecting mirror

The combination of active and passive instruments for use in determining the alignment relationship between the front and rear wheels of a four wheel vehicle, the instruments of the combination comprising: (a) passive instruments on each of the rear wheels, each having a light beam reflecting mirror and scales; and (b) active instruments on each of the front wheels, each of said active instruments including: 1. an elongated body pivotably carried by the front wheel in position to point one end toward a passive instrument on the same side of the vehicle, and to extend an opposite end beyond the front wheel so as to be in line of sight with a similar end of a similar elongated body carried by the companion front wheel; 2. A source of light in said body for projecting a first light beam in a direction toward the passive instrument, and for projecting a second light beam internally toward said opposite end of said body; 3. light beam reflecting means pivotably mounted in and adjacent said opposite end of said body for receiving the internally projected light beam and reflecting that internal beam laterally outwardly of said body at an angle to the internally projected light beam for striking a similar body on the companion steerable wheel; 4. first manipulative means operably mounted adjacent said elongated body carried by that front wheel for effecting pivoting movement of said elongated body in a horizontal plane; 5. second manipulative means operably mounted on said opposite end of said elongated body for pivoting said light beam reflecting means mounted therein for changing the angular direction of light beam reflection; and 6. visual means associated with said elongated body and being rendered responsive to said first and second manipulative means for mutual cooperation in visually displaying the extent and direction of pivoting movement of said elongated body in the horizontal plane, as well as the extent and direction of pivotal movement of said light beam reflecting means.
