I've been working on a system to do my own wheel alignment at home in the garage. I'm one csob and this is getting to be a lot of work, but I like to be able to do things myself. The general idea is to use a laser light that points in the same direction of the wheel and reflects back from a mirror in front of the car. If the mirror is square to the centerline of the car, you can see the toe angle in the light reflected from the mirror. Having the mirror several feet in front of the car will make measuring small angles easier. The real problem becomes setting the rear wheels as they must be symetric about the centerline of the car.
To find the centerline of the car I decided to use the wheel mounting surfaces with the car up on....jack stands where it belongs. I dropped a plumb bob from each corner and marked it on the garage floor. Attached image(s)

I've done the strings before and never thought that it was very accurate. Just something about trying to measure small angles with a scale or tape measure. Besides, I love playing with the laser lights in the dark. (IMG:style_emoticons/default/biggrin.gif) |
