Under what circumstances is a wheel alignment generally performed?

[DeVivian]

Wheel alignment is typically performed under the following circumstances: damage to the chassis and suspension, tire wear, removal of axle or suspension components, and vehicle pulling to one side. The purpose of wheel alignment is to maintain stable straight-line driving and easy steering, while reducing wear on tires and steering components during operation. Unlike regular maintenance, wheel alignment is a repair procedure and is unnecessary unless issues arise. It is only required when problems occur. Wheel alignment uses the vehicle's four tires as a reference, adjusting parameters such as caster angle, kingpin inclination angle, front wheel camber, front wheel toe, and rear wheel toe to achieve a relatively balanced state among the four tires, thereby improving driving stability.
