What:  An important part of vehicle ride control is directional control.  Will the vehicle travel straight down a highway?  Will it steer easily?  Will the tires be subject to minimum wear?  Will the steering wheel return to the straight-ahead position after turning a corner?  For the answer to be YES to all these questions, the vehicle must be properly aligned.

How:  Wheel alignment is the adjustment of angles made by the front wheels in relation to 1) the vehicle's suspension (caster); 2) the road (camber); and 3) each other (toe).  The alignment of one of these angles affects the other two.  All three angles are adjustable on coil spring and torsion bar suspension systems.

When checking or adjusting alignment, tire pressure should be up to manufacturer specifications.  Low tire pressure will affect alignment.
