1. A wheel alignment apparatus for measuring toe angle of a wheel of a vehicle comprising: a main body;a scale slider disposed on the main body and comprising: i. one or more measurement scales; andii. a centering marker; anda toe positioning pin projecting from an end of the main body and aligned with the scale slider,wherein the scale slider is configured to slide along a plane that extends horizontally when the wheel alignment apparatus is in a position for measuring the toe angle and the scale slider is adjustable to a plurality of positions. 2. The wheel alignment apparatus of claim 1, wherein the one or more measurement scales comprise a positive region and a negative region. 3. The wheel alignment apparatus of claim 1, wherein the slider comprises a magnifying lens. 4. The wheel alignment apparatus of claim 1, comprising a second toe positioning pin on a second end of the wheel alignment apparatus. 5. The wheel alignment apparatus of claim 1, comprising one or more camber positioning pins on the bottom of the wheel alignment apparatus. 6. The wheel alignment apparatus of claim 1, comprising one or more camber positioning pins on the bottom of each end of the wheel alignment apparatus. 7. The wheel alignment apparatus of claim 1, wherein when the wheel alignment apparatus is in the position for measuring the toe angle, a plane that bisects the toe positioning pin and the scale slider extends vertically. 8. A wheel alignment apparatus for measuring toe and camber angles of a wheel of a vehicle comprising: a main body comprising a first end and a second end;a scale slider that slides on a first side of the main body from the first end toward the second end, the scale slider comprising: i. one or more measurement scales; andii. a centering marker; anda toe positioning pin projecting from the first end of the main body; andfirst and second camber positioning pins for positioning against a wheel to measure camber angle, the camber positioning pins extending from a second side of the main body that extends between the first and second ends, the first camber positioning pin being proximate the first end and the second camber positioning pin being proximate the second end,wherein the scale slider is adjustable to a plurality of positions. 9. The wheel alignment apparatus of claim 8, wherein the one or more measurement scales comprise a positive region and a negative region. 10. The wheel alignment apparatus of claim 8, wherein the slider comprises a magnifying lens. 11. The wheel alignment apparatus of claim 8, comprising a second toe positioning pin on a second end of the wheel alignment apparatus. 12. The wheel alignment apparatus of claim 8, wherein the main body is adjustable to fit the diameter of a plurality of different sized wheels. 13. The wheel alignment apparatus of claim 12, wherein the main body adjusts telescopically. 14. The wheel alignment apparatus of claim 8, wherein an angle gauge is attached to the main body. 15. The wheel alignment apparatus of claim 14, wherein the angle gauge is detachable. 16. The wheel alignment apparatus of claim 8, wherein the scale slider is configured to slide along a plane that extends horizontally when the wheel alignment apparatus is in a position for measuring toe angle. 17. A method for measuring a toe angle of a wheel of a vehicle using a wheel alignment apparatus comprising: placing the wheel alignment apparatus on a rear edge portion of an outward facing surface of the wheel so that the wheel alignment apparatus is in a perpendicular position relative to a rotational plane of the wheel and positioned between the outward facing surface of the wheel and a reference marker;moving a scale slider of the wheel alignment apparatus to a first position so that a centering marker on the scale slider of the apparatus aligns with the reference marker;placing the wheel alignment apparatus on a front edge portion of the outward facing surface of the wheel so that the wheel alignment apparatus is in a perpendicular position relative to a rotational plane of a wheel and positioned between the outward facing surface of the wheel and the reference marker; anddetermining a toe measurement from a second position on the measuring scale where the reference marker intersects the measurement scale of the wheel alignment apparatus at an offset from the centering marker on the measurement scale of the scale slider. 18. The method of claim 17, wherein the reference marker comprises a string that is parallel to a chassis centerline of a vehicle. 19. The method of claim 17, wherein the reference marker comprises a laser beam. 20. The method of claim 17, wherein the second position in the negative region of the measurement scale indicates a wheel is toe-in. 21. The method of claim 17, wherein the second position in the positive region of the measurement scale indicates a wheel is toe-out. 22. The method of claim 17, wherein the second position on the centering mark of the measurement scale indicates zero toe angle. 23. The method of claim 17 further comprising measuring camber using the wheel alignment apparatus, wherein measuring camber comprises: extending a telescopic camber arm of the wheel alignment apparatus to fit a diameter of the wheel;placing the wheel alignment apparatus across the diameter of a wheel using one or more camber positioning pins; anddetermining a camber angle of the wheel by reading the angle gauge.
