What should I do if the Buick Excelle's body shakes while driving?

[Shelly]

If the Buick Excelle's body shakes while driving, it is recommended to perform a four-wheel dynamic balance and four-wheel alignment. If the issue persists after these adjustments, consider replacing the steel rims. Possible causes of body shaking while driving include: 1. Insufficient tire pressure; 2. Incorrect front wheel camber angle data; 3. Loose front lower control arm ball joints, which can also cause lateral swaying; 4. Excessive steering gear clearance, which can also lead to lateral swaying; 5. Loose steering ball joints, which can also result in lateral swaying. A car's wheel is an assembly consisting of the tire and the rim. However, due to manufacturing variations, the mass distribution of this assembly may not be perfectly uniform. When the wheel rotates at high speeds, this can lead to dynamic imbalance, causing the wheel to shake and the steering wheel to vibrate while driving. To prevent or correct this phenomenon, weights are added to the wheel in dynamic conditions to balance the edges of the wheel. This correction process is known as dynamic balancing.
