What is the purpose of a four-wheel alignment for a car?

[AmaraMarie]

The purpose of a four-wheel alignment for a car is as follows: 1. It ensures the vehicle's straight-line tracking and handling performance. 2. It improves the vehicle's steering response and ensures the returnability of the steering system. 3. It prevents improper stress on bearings, avoiding damage and loss of precision. 3. It ensures tight contact between the tires and the ground, reducing abnormal tire wear and irregular tread wear, and guarantees stability during turns. The conditions requiring a four-wheel alignment are as follows: 1. Tire pressure and tire tread wear: Uneven tire wear indicates a fault in certain aspects such as the tires, steering system, or suspension. 2. Wheel wobble: Wobble is a condition where the tire rotates unstably due to various reasons, and it refers to irregular up-and-down or side-to-side movement of the wheel and tire. 3. Vehicle pulling: Pulling refers to the situation where the vehicle drifts from its intended straight path while driving on a straight road, with the steering wheel not subjected to any external force, causing the vehicle's direction to deviate.
