A vehicle includes a pair of wheel-mounting spindles respectively mounted to a pair of vertically swingable wheel support arms for being steered about respective king pin axes. During assembly of the vehicle on an assembly line, right- and left-hand laser toe gauges are mounted to the spindle shafts in a defined orientation wherein target surfaces of the gauges lie along a respective king pin axis. Length-adjustable tie-rods are coupled to the spindles and adjustable in order that a laser beam emitted from one toe gauge impinges on the target of the other toe gauge when the toe-in is within a prescribed range for resulting in steering and tire wear characteristics. The toe gauges are constructed such that the laser beam direction may be adjusted to calibrate the toe gauge for the particular vehicle being assembled.

1. A toe gauge, adapted for use with a substantially identical companion toe gauge in gauging the toe of a vehicle having a wheel spindle mounted to a wheel support for swiveling about a king bolt axis and being adjustable for effecting toe changes in a wheel mounted to the spindle, comprising: an elongate body; an attaching member joined to said elongate body adjacent a first end of said body and cooperating with said body to define a spindle receptacle having a first axis and adapted for receiving, and being supported by, the vehicle wheel spindle for swiveling about a spindle axis defined by a wheel mounting shaft of said spindle; a laser beam target surface being fixed to said body and located along a second axis which intersects first said axis at a location on an opposite side of said body from said attaching member, and defines a included acute angle with said first axis so as to be located along said king bolt axis when said gauge is in a preselected angular location about said spindle axis and adapted for being impinged by a laser beam of a companion gauge mounted on an opposite side of the vehicle when the toe of a wheel at the opposite side of the vehicle is within a desired range; a locator positioned along said second axis between said target surface and said first axis so as to engage structure associated with said spindle so as to retain said gauge in said preselected angular location; and a laser unit mounted to said body at a location approximately along said second axis for directing a beam toward a target surface of the companion gauge. 2. The toe gauge, as defined in claim 1, wherein said attaching member is in the form of a cylindrical receptacle adapted for receiving said shaft of said spindle.3. The toe gauge, as defined in claim 2, and further including a normally closed switch mounted adjacent said receptacle and having a switch element projecting into said receptacle for being actuated to a position for closing said switch when said receptacle is mounted on a spindle shaft for gauging the toe thereof; and a pair of electrical leads extending from said switch to said laser unit for energizing the latter only when said receptacle is located on said spindle shaft, whereby inerrant energization of said laser unit is prevented.4. The toe gauge, as defined in claim 3, wherein said pair of electrical leads each have a separable coupler located therein between said switch and said laser unit, whereby said coupler of each lead may be separated, and recoupled to a power source so that said laser unit may be powered without closing said switch.5. The toe gauge, as defined in claim 1, wherein said locator includes a notch adapted for receiving a lower end of a king bolt.6. The toe gauge, as defined in claim 1, wherein said toe gauge includes an adjustable mounting for said laser unit for permitting said laser unit to be adjusted so as to change the direction of said beam.7. The toe gauge, as defined in claim 4, wherein said toe gauge includes a laser unit housing having a bore having a longitudinal axis; said laser unit including a cylindrical grommet; and said adjustable mounting including at least one adjustment ring mounted in said bore of said housing for swiveling about said axis and having an eccentric bore receiving said cylindrical grommet for shifting the latter relative to said axis for adjusting the angularity, and/or fore-and-aft position of said beam. 8. The toe gauge, as defined in claim 7, wherein said adjustable mounting includes a second adjustment ring mounted in said bore for swiveling about said axis of said bore of said housing; and said second adjustment ring including an eccentric bore receiving said at least one adjustment ring, whereby said at least one and second adjustment rings may be swiveled relative to each other so as to adjust the angularity, and/or fore-and-aft position of said beam.9. The toe gauge, as defined in claim 8, wherein said at least one and second adjustment rings are each provided with diametrically opposite pairs of pin receptacles adapted for receiving pins of respective adjustment tools.10. A method for setting the toe-in of a steerable vehicle including a steering shaft coupled to right- and left-hand spindles by right- and left-hand, length-adjustable tie rods, with the right- and left-hand spindles being mounted to respective vertically swingable wheel support arms for swiveling about respective king pin axes, the method including the steps of: (a) locking the steering shaft in a position corresponding to that for effecting straight ahead movement of the vehicle; (b) placing respective toe gauge targets at like locations along each king pin axis; (c) placing a beam emitting laser at like locations adjacent each toe gauge target; and (d) adjusting each length-adjustable tie-rod until the beam emitted by each laser impinges on the target adjacent the other laser.
