Ok.. This may sound really dumb, but what the heck does a place do when they do a front-end alignment on your car??? I know more about planes.. Wait... That's why I'm here, aint it!!  Big grin :-P

Basically its the adjustment of the camber and caster of the front wheels. Right guys?

okay,
I went and looked more into it and i found the idiot deff of camber and caster...

Caster is the fore or aft slope of the steering axis. The steering axis is a line drawn through the upper and lower ball joints of the knuckle. Positive caster is when the bottom of the steering axis line is in front of the tire's contact patch. Zero caster is when the steering axis is at 0o. Positive (shown) caster ensures good stability, helps maintain straight-ahead direction and promotes steering wheel self-centering. Too much positive caster causes hard steering, excessive road shock and shimmy.



Camber is the inward or outward tilt of the front tires as viewed from the front. Inward tilt is negative, outward tilt is positive. Camber is used to distribute load across the entire tread. Improper camber makes the tire wear on one edge, and causes the vehicle to pull to the side that has the most positive camber.

And..they will check toe-in and toe-out, which is the degree that the front wheels "aim" towards or away from the centerline of the vehicle when viewed from the top. Most, but not all cars are near "0", but can be slightly toed (high performance cars are usually toed out slightly for handling). The shop will also check the rear alignment, particularly important on vehicles with independent rear suspension designs, but, solid "live" axles and single beam rear suspensions on the less-expensive front wheel drive cars are susceptable going out of align after severe use over poor road conditions or "kissing the curb".

Good shops will also make sure all four wheels are "plumb" so the vehicle tracks straight and true and does not "dogtrack". Regards...Jack



all best; jack
