Guangdong Roadbuck Technology Sharing: In What Situations Do New Energy Vehicles Need Four-Wheel Alignment?

New energy vehicles need to do four-wheel alignment in the following situations, which are mainly based on the driving status of the vehicle, component replacement or repair, and judgment of special driving scenarios:
1. The driving state of the vehicle is abnormal
1. Abnormal tire wear: When the tire has abnormal wear phenomena such as inner or outer bias and different shades of tread, it indicates that the four-wheel alignment parameters may have deviated from the standard value. For example, new energy vehicles are more prone to bias wear under the high torque output of the motor due to the increased load of the chassis due to the battery pack.
2. The steering wheel is incorrect or the vehicle is deviating: If the steering wheel needs to be continuously corrected when the vehicle is driving in a straight line, or automatically offset to one side, it means that there is a deviation in parameters such as the front beam of the front wheels and the caster of the kingpin. This deviation can affect the accuracy of the steering system, increase driving fatigue, and even cause safety hazards.
3. Steering wheel shaking at high speeds: When the speed exceeds a certain threshold (such as 80km/h), the steering wheel shakes regularly, which may be caused by abnormal wheel balancing or four-wheel alignment parameters. Four-wheel alignment corrects wheel inclination and reduces vibration at high speeds.
2. After the replacement or repair of parts
1. Replace new tires or hubs: The specifications and patterns of new tires may be different from old tires, and after replacement, it is necessary to ensure that the angle of the wheels and the suspension system matches through four-wheel alignment to avoid abnormal tire wear due to parameter deviations.
2. Maintenance of the steering or suspension system: After the steering rod, shock absorber, suspension arm and other components are replaced or repaired, their installation position or angle may change, and the original parameters need to be restored through four-wheel alignment to ensure the driving stability of the vehicle.
3. After chassis repair or collision: After a collision or repair of chassis components (such as subframes, control arms), the body structure or suspension system may be deformed, resulting in inaccurate four-wheel alignment parameters. At this time, it is necessary to comprehensively detect and adjust the parameters to ensure that all parts of the chassis work together.
3. Special driving scenarios or mileage accumulation
1. After long-term parking: If the vehicle is parked for more than 3 months, rubber parts (such as suspension bushings) may affect the four-wheel alignment parameters due to aging or deformation. Re-check and adjust the parameters to restore the driving stability of the vehicle.
2. Before self-driving travel: Complex road conditions (such as bumps and potholes) can easily lead to uneven chassis stress and cause parameter shifts. Pre-inspection four-wheel alignment can detect and solve problems in advance to avoid potential safety hazards during the journey.
3. Reach the recommended mileage or time: It is recommended to check the four-wheel alignment every 20,000 kilometers (some models may be shortened to 15,000 kilometers) due to the increased chassis load of the battery pack to prevent tire wear or unstable driving caused by parameter shifts.
