How does a four-wheel alignment differ from a two-wheel alignment?

A four-wheel alignment adjusts the angles of all four wheels to ensure that they are parallel and aligned properly relative to each other and the vehicle's centerline. This is important for maintaining proper vehicle handling, tire wear, and overall driving stability. The process involves adjusting the camber, toe, and sometimes the caster angles of the rear wheels in addition to the front, which is what differentiates it from a two-wheel alignment.

In contrast, a two-wheel alignment only addresses the front wheels. This type of alignment is generally sufficient for vehicles that do not have adjusting capabilities in the rear suspension and is typically performed when only the front-end components have been replaced or serviced. However, if the rear suspension is adjustable or if the vehicle is a newer model, a four-wheel alignment can be necessary to ensure optimal performance and tire longevity.

The other options do not accurately describe the primary differences between the two types of alignments. The assertion that a four-wheel alignment is more affordable is not necessarily true, as it tends to be more expensive due to the additional work required. Additionally, the notion that a four-wheel alignment is only for trucks is incorrect; it applies to any vehicle that has an adjustable rear suspension.
