Your car’s frame, steering and suspension components (the chassis system) all depend on each other, because they all affect alignment and steering response. A change in any one component can affect the others. Since all of these parts work together as a system, it is necessary to have each component checked when making adjustments or replacing parts.

Which Parts Solve Which Problems?

	Idler Arms hold the steering linkage in place. By replacing worn idler arms, you can reduce vehicle wander, excessive play in the steering wheel and abnormal tire wear.
	Ball Joints are the pivot points on which the front wheels turn. By replacing worn ball joints, you can reduce front-end noise, looseness and tire wear.
	Tie Rod Ends connect the steering arm to the linkage. By replacing worn tie rod ends, you can reduce front-end looseness, vibration, misalignment and excessive tire wear.
	Bushings help dampen front-end movement, keep body roll to a minimum and help dampen wheel shock and vibration. Replacing worn bushings helps eliminate noise and play and makes handling safer and more predictable.

Your Tires — Are They Worn Like This?

Cupped Tire Wear: Produced by an unbalanced tire condition, faulty wheel bearings or weak shock absorbers.
Scrubbed Tire Wear: Usually caused by excessively loose, worn or bent tie rod ends, idler arms or steering linkage components.
Uneven Tire Wear: A result of incorrect alignment or worn ball joints and bushings.
Variable Tire Wear: Caused by a combination of misalignment, weak shocks, worn control arm bushings and excessively loose ball joints.

Remember:
A correct alignment requires checking all components of the system. The life of your tires and related parts can be greatly extended with proper maintenance. That saves you money. But more importantly, a correct alignment provides a maximum level of safety for you and your family.
