What Does Four-Wheel Alignment Adjust?

[KeeganRose]

Front wheel alignment adjusts four parameters: caster angle, kingpin inclination angle, camber angle, and toe-in. Rear wheel alignment adjusts the camber angle and toe-in for each rear wheel. Here is additional information: 1. Four-Wheel Alignment: Four-wheel alignment is based on the four-wheel parameters of the vehicle, adjusted to ensure good driving performance and reliability. For the steering wheels, steering knuckles, and front axle of a car, their installation has a specific relative position, which is called front wheel alignment. Similarly, the rear wheels also have a relative installation position with the rear axle, called rear wheel alignment. Together, these are referred to as four-wheel alignment. 2. Benefits: Enhances driving comfort; reduces fuel consumption; extends tire lifespan; ensures driving stability; reduces wear on chassis suspension components; improves driving safety.
