Is Four-Wheel Alignment Free at 4S Shops?

[SanIsabella]

Some 4S shops offer free four-wheel alignment services for car owners, while others charge a fee. Here are specific details about four-wheel alignment at 4S shops: 1. Definition: Car tires have various parameters and are not perfectly perpendicular to the ground. The front wheels have settings like toe-in and camber angles. During daily driving, passing over speed bumps and rough roads can alter the four-wheel alignment data due to impact forces. Incorrect four-wheel alignment can lead to issues like vehicle drift and uneven tire wear. Therefore, periodic four-wheel alignment is necessary to calibrate the wheel parameters, ensuring optimal vehicle handling. 2. Type Explanation: For sports cars or racing vehicles, four-wheel alignment data is crucial, and racing teams typically employ professional technicians to adjust these settings. Performing four-wheel alignment requires specialized equipment and trained personnel to achieve accurate results. Drivers can also adjust the settings based on their driving habits and typical road conditions. Some vehicles feature multi-link rear suspensions, allowing for more adjustable parameters on the rear wheels.
