Under What Circumstances Does a Car Need a Four-Wheel Alignment?

[DelPeter]

Circumstances under which a car needs a four-wheel alignment include: 1. The steering wheel feels heavy, shakes, pulls to one side, is misaligned, or does not return to center while driving; 2. Issues with tire pressure and uneven tire tread wear; 3. Wheel vibration or wobbling; 4. The vehicle pulls to one side. The functions of a four-wheel alignment are: 1. To maintain stable straight-line driving and ease of steering; 2. To ensure that the rear wheels after turning or the front wheels before turning can automatically return to the correct position; 3. To reduce wear on tires and steering components during driving; 4. To maintain the optimal driving angle between the tires and the vehicle body. The four-wheel alignment function is based on the vehicle's four-wheel parameters and involves adjustments to ensure good driving performance and a certain level of reliability.
