The steering geometry is all of the alignment angles of your wheels in relation to each other and in relation to your vehicle. These angles have been engineered into your vehicle so that while you are driving on a flat surface your vehicle will not have a tendency of wandering over to the right or to the left. A well aligned vehicle will help you straighten out again after you have turned a corner. Bear in mind that, should your vehicle hit a curb hard enough after a wheel alignment it is quite possible the impact could have altered the alignment.

The correct alignment of your wheels depend on several components linking the steering wheel to the vehicle wheels. Components such as; the tie rod ends, the ball joints, the rack and pinion, which is an alternate style of a steering box, the struts and the king pins. Wear in some of these components could alter the steering geometry.
